Difficulty:

(N/A)

Question Stats:

0% (00:00) correct 100% (01:20) wrong based on 2 sessions
1. Teresa: Manned spaceflight does not have a future, since it cannot compete economically with other means of accomplishing the objectives of spaceflight.
Edward: No mode of human transportation has a better record of reliability: two accidents in twenty-five years. Thus manned spaceflight definitely has a positive future.

Which of the following is the best logical evaluation of Edward's argument as a response to Teresa's argument?
1. It cites evidence that, if true, tends to disprove the evidence cited by Teresa in drawing her conclusion.
2. It indicates a logical gap in the support that Teresa offers for her conclusion.
3. It raises a consideration that outweighs the argument Teresa makes.
4. It does not meet Teresa's point because it assumes that there is no serious impediment to transporting people into space, but this was the issue raised by Teresa.
5. It fails to respond to Teresa's argument because it does not address the fundamental issue of whether space activities should have priority over other claims on the national budget.


2. Black Americans are, on the whole, about twice as likely as White Americans to develop high blood pressure. This likelihood also holds for westernized Black Africans when compared to White Africans.
Researchers have hypothesized that this predisposition in westernized Blacks may reflect an interaction between western high-salt diets and genes that adapted to an environmental scarcity of salt.

Which of the following statements about present-day, westernized Black Africans, if true, would most tend to confirm the researchers' hypothesis?
1. The blood pressures of those descended from peoples situated throughout their history in Senegal and Gambia, where salt was always available, are low.
2. The unusually high salt consumption in certain areas of Africa represents a serious health problem.
3. Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption.
4. Blood pressures are low among the Yoruba, who, throughout their history, have been situated far inland from sources of sea salt and far south of Saharan salt mines.
5. No significant differences in salt metabolism have been found between those people who have had salt available throughout their history and those who have not.


3. The following proposal to amend the bylaws of an organization was circulated to its members for comment.
When more than one nominee is to be named for an office, prospective nominees must consent to nomination and before giving such consent must be told who the other nominees will be.

Which of the following comments concerning the logic of the proposal is accurate if it cannot be known who the actual nominees are until prospective nominees have given their consent to be nominated?
1. The proposal would make it possible for each of several nominees for an office to be aware of who all of the other nominees are.
2. The proposal would widen the choice available to those choosing among the nominees.
3. If there are several prospective nominees, the proposal would deny the last nominee equal treatment with the first.
4. The proposal would enable a prospective nominee to withdraw from competition with a specific person without making that withdrawal known.
5. If there is more than one prospective nominee, the proposal would make it impossible for anyone to become a nominee.


4. Which of the following best completes the passage below?

In a survey of job applicants, two-fifths admitted to being at least a little dishonest.
However, the survey may underestimate the proportion of job applicants who are dishonest, because
1. some dishonest people taking the survey might have claimed on the survey to be honest
2. some generally honest people taking the survey might have claimed on the survey to be dishonest
3. some people who claimed on the survey to be at least a little dishonest may be very dishonest
4. some people who claimed on the survey to be dishonest may have been answering honestly
5. some people who are not job applicants are probably at least a little dishonest


5. Which of the following, if true, most serinously weakens the conclusion that cigarette companies could have dropped advertising without suffering economically?
1. Cigarette advertisements provide a major proportion of total advertising revenue for numerous magazines.
2. Cigarette promotion serves to attract first-time smokers to replace those people who have stopped smoking.
3. There exists no research conclusively demon-strating that increases in cigarette advertising are related to increases in smoking.
4. Advertising is so firmly established as a major business activity of cigarette manufacturers that they would be unlikely to drop it.
5. Brand loyalty is typically not very strong among those who smoke inexpensive cigarettes.

E. Teresa says that manned spaceflight has no future because it costs too much, and Edward replies by stating that it's the safest form of transportation that exists. He completely fails to respond to her point about the cost.

D. This provides direct evidence about the passage's hypothesis.

E. The proposal makes it so you have to consent to be a nominee before becoming a nominee, and that you have to know who the other nominees are before you can consent. So if there are three people who could become nominees, no one would ever be able to give their consent first, because no one ELSE has given consent. It's a logical circle.

A. Obviously, some dishonest people may very well have lied about being dishonest, and if they had told the truth, the number of people replying about being dishonest would go up.

Is there a passage missing here?

TehJay, good formatting.
1) D, not E. We are not talking about national budget. Ed assumes that all other factors are set and only safety is the concern. So he ignores whatever Teresa is telling and proceeds with his nonsense.
2) C provides the answer I believe. It gives us the response of the africans to the modern day situation and that strengthens the scientist's conclusion. This is a bit weird though.
3) Is E. You got it right.
4) A
5) B. and here is why:
Which of the following, if true, most seriously weakens the conclusion that cigarette companies could have dropped advertising without suffering economically?
Here you have to choose something that tells us the reason for why the cig companies must invest in Adv. C cannot be the answer. C implies it doesn't matter even if you adv or not. the answer has to be between B (it attracts newer customers) and E (if you don't adv then ppl without brand loyalty might switch, so you have to keep adv).

OAs please.

D states that Teresa's point had to do with difficulties in transporting people, but she didn't say anything along those lines.

2) C provides the answer I believe. It gives us the response of the africans to the modern day situation and that strengthens the scientist's conclusion. This is a bit weird though.

C weakens the hypothesis. The hypothesis is that Black Africans have higher blood pressure because they are genetically predisposed to it, but C claims that in fact both White and Black Africans had high blood pressure, but White Africans changed their diet and thus reduced their blood pressure.

Bundle of 5 question from another site :shock: Great !

For the first one ..... TehJay ....... I also selected E ....... but it is definitely a stretch to put national budget etc ......... maybe the impediment mentioned in D is the $$$$s for the space flight.
