Sue: Commercial flights currently contribute more carbon dioxide to the atmosphere in one year than does the whole of Africa. If we want to reduce global warming we need to restrict the number of flights we take.
Dave: Did you know that by taking one inter-continental flight you cause more pollution than you would in twelve months of car travel?
Dave’s response to Sue’s comment serves to
 

Answer: B


Explanation:

B is the best option
Since Dave’s comments don’t challenge what Sue says, we can eliminate answers E and C (mitigate = lessen). His comments reinforce what she says and so A sounds tempting but is wrong since Dave talks about pollution in general and
doesn’t mention carbon dioxide. Of the remaining choices, B is best since Dave does give information that suggests, like Sue, that we should take fewer flights. (D is incorrect mainly because Dave is not talking about the ‘effect’ of pollution. Note
how careful you have to be that all the words in an answer are exactly right.
22)

CROSS8 + TRIANGLE10 = CIRCLE2
TRIANGLE20 + CROSS14 = SQUARE6
SQUARE4 + CIRCLE2 = DIAMOND48
CIRCLE6 + SQUARE4 = DIAMOND?
The Value of DIAMOND is

Answer: C


Explanation:

The Bolden figure are the answers of each equation
-8 + 10 = 2
20 – 14 = 6
4 + 2 = 6
The Value of DIAMOND is 6
23)

A proposed ordinance requires the installation in new homes of sprinklers automatically triggered by the presence of a fire. However, a home builder argued that because more than ninety percent of residential fires are extinguished by a household member, residential sprinklers would only marginally decrease property damage caused by residential fires. Which of the following, if true, would most seriously weaken the home builder's argument?

Answer: E


Explanation:

The Best Option is E
The home builder reasons from evidence about most residential fires to a conclusion about the effectiveness of sprinklers in preventing property damage. But this reasoning is faulty because of the possibility that most of the property damage results from the minority of fires excluded from the builder's evidence. That possibility is realized if E is true. Thus, E is the best answer.
24)

Increase in the level of high-density lipoprotein (HDL) in the human bloodstream lower bloodstream-cholesterol levels by increasing the body's capacity to rid itself of excess cholesterol. Levels of HDL in the bloodstream
of some individuals are significantly increased by a program of regular exercise and weight reduction.

The Best Option is D
If increased HDL levels cause reduced cholesterol levels and if a certain program increases HDL levels in some individuals, it follows that some individuals who undertake that program achieve reduced cholesterol levels. D is thus correctly inferable and the best answer. A cannot be correctly inferred because the statements do not establish any connection between being underweight and levels of cholesterol. Neither of B and E is inferable, since there is no indication that exercise alone is either necessary or sufficient to increase HDL levels or to decrease cholesterol levels. C is inappropriate because other
methods of cholesterol reduction are not addressed.
25)

When limitations were in effect on nuclear-arms testing, people tended to save more of their money, but when nuclear-arms testing increased, people tended to spend more of their money. The perceived threat of nuclear catastrophe, therefore, decreases the willingness of people to postpone consumption for the sake of saving money. The argument above assumes that

C is the best Option
On the basis of an observed correlation between arms testing and people's tendency to save money, the argument concludes that there is a causal connection between a perception of threat and the tendency not to save. That connection cannot be made unless C, linking the perception of threat to the amount of testing being done, is assumed to be true. Therefore, C is the best answer. The conclusion does not depend on there having been an increase in the perceived threat over time or on how many people supported the development of nuclear arms. Hence, neither of A and B is assumed. The argument does not deal with those who supported arms limitations or with the availability of consumer goods. Thus, D and E are not assumed.
