While 65% of the eligible voters who were recently polled favor Perkins over Samuels in the coming election, the results of that poll are dubious because it was not based on a representative sample. Given that Perkins predominately advocates the interests of the upper-middle class and that the survey was conducted at high-priced shopping malls, it is quite probably that Perkin's supporters were overrepresented.

Which one of the following statements most accurately expresses the main conclusion of the argument?

A) The poll was intentionally designed to favor Perkins over Samuels.

B) Samuel's supporters believe that they were probably not adequately represented in the poll.

C) The poll's results probably do not accurately represent the opinions of the voters in the coming election.

D) Samuels is quite likely to have a good chance of winning the coming election.

E) Those who designed the poll should have considered more carefully where to conduct the survey.

My bet is C. Waiting for the original answer. "Probably" and "representative" seem to be the key words.

Here's a question that is a little more challenging. I actually had a question on the GMAT with the same argument structure but it was quite a bit longer.

Quote:
Reza: Language requires the use of verbal signs for objects as well as for feelings. Many animals can vocally express hunger, but only humans can ask for an egg or an apple by naming it. And using verbal signs for objects requires the ability to distinguish these objects from other objects, which in turn requires conceptual thought.

If all of Reza's statements are true, then which one of the following must also be true?

A) Conceptual thought is required for language

B) Conceptual thought requires the use of verbal signs for objects.

C) It is not possible to think conceptually about feelings.

D) All humans are capable of conceptual thought.

E) The vocal expressions of animals other than humans do not require conceptual thought.

I thought the answer was D. Can't find an OA posted by Franklin. I think A is wrong because conceptual thought may or may not be required for language (since language consists of both verbal signs for objects AS WELL AS FEELINGS). Therefore, although conceptual thought may be required for ONE PART of language, but not for the other.

Why D is correct: since one of the premise is that "only humans can distinguish between objects", why can't we generalize to assume that ALL humans can? It does not mention MOST/MANY/FEW/SOME.

I think the answer to this one should be A.

It is just a logical path of cause and effect. One thing causes the other, which causes the next and which causes the next. The key word is "REQUIRE". If one thing requires the other to be true for it to happen, it is mandatory. When you trace all the events in logical succession you realise that:

A) Conceptual thought is required for language.

^Agreed. Language requires verbal signs for object plus feelings. verbal signs for objects require conceptual thought. so conceptual though is required for language. C

D is wrong because it says "All humans are capable of conceptual thought". The question tells us that only humans are capable of such thought as a means of excluding all other animals. There still may be humans who are not capable of conceptual thought. ( for example: someone whose brain is not functioning correctly)

Scientist: A controversy in paleontology centers on the question of whether prehistoric human ancestors began to develop sophisticated tools before or after they came to stand upright. I argue that they stood upright first, simply because advanced toolmaking requires free use of hands, and standing upright makes this possible.

Which one of the following statements, if true, most weakens the scientist's argument?

A) Many animals that do not stand upright have learned to make basic tools.

B) Advanced hunting weapons have been discovered among the artifacts belonging to prehistoric human ancestors who did not stand upright.

C) Many prehistoric human ancestors who stood upright had no sophisticated tools.

D) Those prehistoric human ancestors who first came to stand upright had no more dexterity with their hands than did those who did not stand upright.

E) Many of the earliest sophisticated tools did not require their users to be able to stand upright.

I marked E

Whats the OA

If the two types of flies have some parasites in common, then the research can't be completely useless.

1) ID Question:
Find the assumption that supports claim. In other words find assumption that will clearly strengthen the conclusion.

2) Breakdown argument:
Let's say sweet-potato whitefly is A and silverleaf whitefly is B.

Scientists search for parasite A to kill whitefly A. Research shows crop pest is whitefly B. The conclusion is that efforts to find parasite A was all for not.

3) State the goal:
Find the assumption that will support the conclusion.

4) Reasoning:
A) All varieties of the sweet-potato whitefly are serious crop pests. WRONG: mentions nothing of parasite
B) If a crop pest has a parasite, that parasite can always be used to control that pest. WRONG: if this was the case then parasite A would have been used on whitefly B
C) The chances of successfully identifying a useful parasite of the new pest have increased since the proper identification of the pest. MAYBE
D) No parasite of the sweet-potato whitefly is also a parasite of the silverleaf whitefly. MAYBE
E) In the last three years, the entomologists found no parasites of the sweet-potato whitefly. WRONG irrelavant

This leaves answers C and D.
Although answer C is true it says nothing to address the outcome of the effort expended to find parasite A.
I am going to say that the answer is D because it clearly states that parasite A cannot be used to stop whitefly B.
