A)

This is the best option. In this option, the subject ( Niklas Luhmann) and main verb (was) can be readily identified.

;#

 

E)

There is an ongoing debate in philosophy and in science about whether language, the means had of expressing our experiences in the world, determines what actually exists.

​C)

A)

The phrase “as much as” is used to compare amounts. This is not the intension of the sentence. This option is incorrect.

B)

The phrase “both in science and in philosophy” correctly fixes the “in as much as” problem in the original sentence. The way the connector “or” is used in the appositive could mean that either language or the means we have of expressing our experiences in the world is what determines what actually exists. Language and the means to express experiences are taken as two separate entities. This is not the best option.

 

C)

This is the best option. In this option the phrase “both in science and in philosophy” correctly fixes the “in as much as” problem in the original sentence. Furthermore, the lack of “or” in the second phrase makes the phrase an adjective clause describing language and removes the ambiguity.

D)

The phrase “as much as” is used to compare amounts. This is not the intension of the sentence. The use of had in the second phrase unnecessarily changes the tense of the sentence, and the use of “or” lends itself to multiple interpretations. This option is incorrect.

E)

The phrase “the means had” has no interpretable meaning in the sentence. This option is incorrect.

This option states “Effectiveness and eloquence should not be confused is the use of language”. This does not make sense. This option is incorrect.

E)

For those of you about to receive the memo, the meeting will be held on the third floor of the Harmon building.

C)

A)

Incorrect. “These” is used to indicate people and objects close at hand, in an isolated group or a group that is easily objectified. There is no indication in this sentence that the speaker’s audience is in an isolated group. The speaker does not know who received the mail; therefore, this group of people cannot be identified easily.

B)

This answer is incorrect. The article “a” is used to indicate one of many and not to refer to specific objects. In this case the speaker is referring to a specific memo; therefore, the article “the” would be the appropriate word.

 

C)

This is the best answer. “Those” is used to indicate people or objects at a distance. It makes sense that the speaker would need to contact the people who haven’t received the memo about where the meeting is being held.

B)

D)

This answer is wrong. The verb time of the first half of the sentence (future) does not agree with the second half (past).

E)

When researching a topic, especially one related to the development of information technologies, it is important that you find current sources.

​E)

A)

This answer is wrong. The opening phrase before the comma is referring to a single topic. “Those” is used for plural references. There is no agreement in number.

B)

Wrong. The article “a” in the answer choice is for singular references while “technologies” is plural. No agreement in number. Plus, “developing” should read as “development” because it is referring to a process (a noun).

 

C)

Wrong. The article “a” in the answer choice is for singular references while “technologies” is plural. There is no agreement in number.

D)

This answer is good but not the best. One would need to use the article “the” before “development” since the passage is referring to a specific area of information technologies. Development is a noun and not a verb.

E)

This is the best answer. One would need to use the article “the” before “development” instead of “a” since the passage is referring to a specific area of information technologies (area is a noun).

A)

Wrong. The information before and after the comma is not contrary. “But” is a conjunction used to express contrary ideas.

B)

Wrong. Transition words like “however” need to be preceded by a semi-colon and followed by a comma.

 

C)

Wrong. When they are used to connect two complete ideas, conjunctions like “and” need to be preceded by a comma.

D)

This is the best answer. We have a transition word “however” preceded by a semi-colon and followed by a comma. The information after the transition word is contrary to the information before the transition word.

E)

The information before and after the comma is not contrary. “But” is a conjunction used to express contrary ideas.

Correct. Bank robbers, by definition, steal, and for them to leave a bag of money behind (at the bank) would go against their purpose. This could explain why they would be in a hurry.

E)

This is a good answer but not the best. The noun “bag” needs an article.

​C)

A)

Wrong. “Was” does not agree in time with the future formation of “will be”.

B)

Wrong. The semi-colon is used between two complete ideas that are very closely related, as if the second idea is a paraphrase of the first, and not as a contradictory idea. It is also used before a transition word, like however, when there are two complete ideas on both sides. In this case there is not transition word.

 

C)

This is the best answer. “However” is used to connect two complete ideas that are contradictory.

D)

This is a good answer but not the best. There should be a comma after “however”.

E)

E)

One solution to global warming would be to abandon trying to slow the process and to develop the technologies that would enable us to survive in harsher conditions.

E)

A)

Wrong. “Or” suggests another option. In this case we are looking for an option that compliments the shift in strategy. Also, there are only a few verbs that can be used in the infinitive with another verb. “Abandon” is not one of them.

B)

This is a good answer but not the best. We are looking for a word that suggests a solution. “But” suggests another contrary idea. We already have the contrary idea mentioned where it says “to abandon”.ct.

 

C)

“But” suggests another contrary idea. We already have the contrary idea mentioned where it says “to abandon”. Plus, there is no certainty that these technologies will work; therefore, a conditional needs to be used with the verb “enable”.

D)

Wrong. Using “can” and “enable” together is redundant.

E)

This is the best answer. There is no certainty that these technologies will work; therefore, a conditional needs to be used with the verb “enable”. The conjunction “and” is appropriate because the answer is a continuation of the original strategy to abandon the idea of trying to combat global warming.

Apple has great influence in today’s electronic-goods market. Amazon named a new service it provides for cloud-based music ‘Cloud Server’. Apple’s decision to take Amazon to court over the use of the name ‘Cloud Server’ will present a possibly insurmountable obstacle to Amazon’s success as a cloud-service provider.

Which of the following, if true, presents the most problems to the credibility of the above argument?
0
Opción múltiple

A)

Previous legal disputes involving companies of such size and influence, such as Amazon and Apple, have ended up in settlements that are of little or no consequence to the future of either company.

;#

B)

Apple has historically won legal battles such as this one making the loosing company agree to its terms with minimal conditions.

;#

C)

Apple’s intention to hinder the progress of any of its direct competitors has been highly quoted in the media. As a result of the legal action Amazon’s market shares have not stopped falling and are increasing their rate of decline.

;#

D)

Both Apple and Amazon have very similar business models, so much so that they have continually achieved success albeit in different service areas. This is the first service area in which they have come head to head.

;#

 

E)

The Federal arbitration commission would not allow a merger of Apple and Amazon, as this could be unfair for smaller competitors.

A)

A)

is the correct option, as the statement reads the legal battle will present an “insurmountable obstacle” and taking this option as true leads us to believe the conflict will be of little consequence.

B)

This option directly strengthens the argument; it does not pose credibility problems, as Apple could directly ask for the change of name or the termination of the cloud-based service by Amazon. This option is incorrect.

 

C)

This option strengthens the argument. We can assume Amazon, or its board of directors is sensible to changes in its market shares, and it may result more costly for the company to pursue its future in cloud-based-music services. This option is incorrect.

D)

The similarity of the business model of the companies is irrelevant to the question. This option is incorrect.

E)

A merger is not mentioned in the argument. This option presents information irrelevant to the argument. This option is incorrect.

0
Opción múltiple

A)

Technological startups today are following what they perceived to be the Google approach so as to lure potential employees with a high degree of creativity.

;#

B)

A recent study on how programmers, designers, and other workers who rely on creative insight for work showed how important a non-stifling, low stress and friendly work environment promotes commitment to tasks and to the values of the company.

;#

C)

At the time of Google’s conception, the lack of leadership and feuding between the large companies that provided search services such as Netscape and Yahoo afforded the basic conditions for growth so commonly denied to startups. This is taken by some technology and finance observers to be the most important factor in Google’s success.

;#

D)

Google is now the most efficient and powerful search engine in the world. There is little competition for it. Most of its growth issues are the political issues some governments find with its open approach to information retrieval.

E)

The measure of a company’s success is not done through its share value, but through an assessment of the improvement of the quality of life its workers have achieved in the time they have worked for it.

C)

A)

This option reinforces the argument, providing further examples of the use, or acceptability of the practices that allegedly helped Google achieve its success. This option is incorrect.

B)

This option makes the argument stronger by providing additional proof that Google’s practices on working conditions could have helped it obtain a competitive edge. This option is incorrect.

 

C)

This is the best answer. This option gives a reason other than work environment for Google’s success. Thus providing a basis for criticism of the argument.

Question 27 of 51 

A well-known theoretical position of human behavioral biology defends the thesis that humans, just like other animals, can be conditioned to respond in certain ways to stimuli, thus setting fertile grounds for behavior modification techniques.

Which of the following could best be construed as a criticism of the above argument?
0
Opción múltiple

A)

A behavioral scientist Abraham Maslow, defined a hierarchy reflecting how humans prioritize their needs. If someone or something is good at satisfyingly meeting these needs, humans will value the thing or person providing satisfaction.

;#

B)

Current courses on human behavioral biology are emphasizing the need for a much more holistic approach to human behavior as compared to approaches in the past. Presenters treat humans as complex entities that, when making decisions, undergo elaborate processes that need many different areas of knowledge to be explained. Because of this the degree to which these choices may be influenced deliberately is ultimately quite low.

;#

C)

The manner in things are organized affects our memory. There much research available that suggests we are more likely to remember the first and last things on a long list than any of the middle items on the same list. This is currently identifiable in marketing as most lists consist of no more than three items.

;#

D)

An interesting theory that deals with esthetics is the attractiveness bias theory, which states that humans are naturally attracted to what they perceive as beauty. This tendency can be used in design to improve the influx and permanence of a certain target audience to publicity events.

;#

 

E)

Size matters choosing the right size for an item users might interact with can be decisive for a user’s choice on whether to interact with it or not. With the advent of mobile devices, much effort is put into the relative size of the components in product pages. The wrong decision about relative size could mean substantial loos of profit, even the demise of company.

B)

A)

This option is giving additional support for the argument stating a manner in which humans could be conditioned. This option is incorrect.

B)

This is the best option. This option states that deliberate influence on human behavior is complex, rendering the argument’s claim that human response to stimuli lends itself behavioral modification, less strong.

 

C)

This option reinforces the claim that human behavior may be modified in that is we organize lists a certain way it is possible to affect the effectiveness in which some items are remembered. We would here be modifying memory a component of human behavior. This option is incorrect.

D)

This option is giving additional support for the argument stating a manner in which humans could be conditioned. In this case by using beauty as a way to attract human audiences. This option is incorrect.

E)

This option is giving additional support for the argument stating a manner in which humans could be conditioned. The argued predictability of human behavior based on relative sizes can be taken to be a tool for the manipulation of such behavior. This option is incorrect.

Question 28 of 51

Government representatives of country X openly state that their country is against violence and the use of such violence to further government goals. This same country is the biggest worldwide manufacturer and exporter of guns and ammunition. Other countries use weapons from country X to either offensively or defensively position themselves, sometimes through the use of violence, in international policy.

Which of the following would best explain the paradox presented by the statement above?

A)

The UN requires all international weapons commerce to be regulated by international commissions so as to keep track of the origin and destination of such weapons.

B)

Some of the most popular guns that are manufactured nowadays come from country Y not country X.

C)

Country X has two main ruling parties, one of which directly benefits from both the internal, and the external sale of such weapons. This political party wields an important amount of political clout in country X.

;#

D)

Country Y has been o long time enemy of country X. The current situation is that country X is dominant and peacefully contributed to country Y’s adoption of different economic policies.

;#

 

E)

There is little moral justification in selling weapons to people you highly suspect will use them against innocent people.

C)

A)

This option is irrelevant. Whether the UN has requirements in place for the regulation of weapons, does not help explain the paradox. This option is incorrect.

B)

This option is irrelevant. The fact that another country produces popular guns does not help explain the paradox. This option is incorrect.

 

C)

This is the best option. That two political parties are dominant may well result in differences between what is stated as international state policy, and what actually takes place.

D)

This option is irrelevant. Economic policies may have to do with the sales of weaponry, but these policies alone, and specially regarding only one other country, do little to explain the paradox away. This option is incorrect.

E)

This is a heartstrings choice. Most people would agree with what this option states, but it does not help explain the paradox. This option is incorrect.

Question 29 of 51 

Some recent studies show how intermittent exercise, exercise not done on a regular basis, can do more harm than good. Most physicians recommend starting exercise regimes as a solution to most of the common ailments people in our modern society suffer. Physicians should pay more attention to these studies so as to first consider the dedication the patient is likely to have towards exercise before recommending they start doing exercise.

Which of these options would most likely weaken the argument above?

0
Opción múltiple

A)

Most of the common symptoms people present to their physicians are associated with a lack of physical activity.

;#

B)

Most people starting an exercise program stop following such program after an average of three weeks.

;#

C)

Most people, who are told they need to do more physical activity by their physicians, are likely to continue doing such activity long after the symptoms that originally took them to the physician are gone.

;#

D)

Most people told to do exercise by their physicians follow the physician’s instructions and regularly exercise for the time it takes for their symptoms to become tolerable. After this happens their interest in exercise wanes and they no longer do the activity regularly. Studies supporting these statements, however, are not as reliable as the ones stating the symptoms stop as exercise begins.

;#

 

E)

Exercise programs, especially the ones recommended by doctors, are boring. This is the main reason people stop doing regular exercise.

D)

A)

This option states that most common symptoms are associated to a lack of physical exercise. It could be construed as a fact that counters the argument. The problem here is that it does not address the regularity of the exercise, a main point in the argument’s conclusion. This option is not the best.

B)

The fact presented by this option would strengthen the argument, not constitute a basis for criticism.

 

C)

This option could constitute a basis for criticism, but the main issue, the regularity in which the exercise is done, is not addressed. This is not the best option.

D)

This is the best option. The regularity of the exercise is the main point presented in the statement. The statement is highly relevant to the argument because it talks specifically of the cases in which physicians recommend exercise regimes. It also addresses the reliability of the studies to support the claims.

E)

This is a heartstrings choice; most people would agree with the statement in this option, but there the statement is irrelevant to the argument’s conclusion.

C)

A)

The statement about the lack of relatedness between work and study does not weaken the argument. It strengthens it. This option is incorrect.

B)

This option states that ivy league schools are trying to become more exclusive. This statement has no relevance to the argument that traditional education is becoming obsolete. This option is incorrect.

 

C)

This is the best option. This option addresses the main point the argument makes. It counters the claim that traditional education is to become obsolete because of the emergent phenomena. This option weakens the argument.

D)

This option is irrelevant to the argument’s conclusion. The argument does not mention difficulty as the main reason for which traditional education is becoming obsolete. This option is incorrect.

E)

The statement this option makes is irrelevant to the argument. The reasoning in the argument does not rest on whether virtual education is cheap or not. The argument talks about traditional education. This option is incorrect.
