The Best Option is E
If the two professor is strict about grades she might possibly still make unfair demands (A) and also have favourites(B). It is possible that she acquired this tendency recently(C), it is possible that few of her students deserved good grades (D), but the fact that she NEVER gives out grades of A could quite possibly label her as being very strict when it comes togiving out grades

Answer: C

Explanation:

Situation: The passage claims that most people involved in espionage, or spying, on their own country are driven byirrational desires. The passage also claims that espionage is a self-destructive behavior. Reasoning: Which of the following is an assumption on which the argument depends? The first sentence lists the reasons that most people commit espionage and claims that all of these reasons are a result of irrational desires. This idea is continued in the second sentence, which claims that anyone thinking rationally would not engage in what the passage deemsself-destructive behavior. Option C correctly identifies the assumption that no one involved in espionage is thinking clearly. The argument in the passage could be severely weakened if it could be demonstrated that some people are thinking rationally when they commit espionage

Answer: E

Explanation:

The question stem asks you to pick the choice from which the statement can be derived, and that's (E). If, as (E) says, anyone who is German is an idealist except for Marx, then all Germans except for Marx are idealists. That being the case, it
would certainly be true that, as the stimulus says, with the exception of Marx, all German philosopher—being a subset of all Germans—are idealists. While this may sound absurd, we're concerned with strict logic here, not content.

Answer: E

Explanation:

The Best Option is E
Choice A is wrong, because as long as a sample is representative, the value of inflation should be accurate. Choice B is wrong because first, we don’t have values that stretch back 3 years, and even if true, this would keep the
inflation value down, not bring it back up. Option C is wrong because if government intervention cannot affect the inflation, you would expect it to stay the same. Choice D is also wrong, because even though you might argue that a 15-year low might be expected to be a one-time occurance, so the figures are likely to rise again, this isn’t refuting a downward trend which might lead to even lower figures. Finally, answer E is the correct one it suggests that an economic crisis kept values down this year specifically, but since the crisis will be over by next year, inflation will likely go back up.

Answer: D

Explanation:

Choice D is correct- there is a big difference between owning a cat, and feeding cats. Old ladies might be feeding stray cats more than families do, which supports the popular belief despite the given facts. Choice A is wrong because other demographic groups would not affect the claim at all. Option B is wrong because the popular belief idea is necessary for
the claim, and the first portion of the text might be based on research. Option C is wrong because the types and ages of cats is completely irrelevant. Option E might produce some bias, but otherwise it doesn’t not really point out any flaws.
