B
Since jungle fever is 'highly contagious,' choice B provides an alternative explanation for the high incidence of jungle fever in the white mice injected with Serum D. Choice C is not relevant as we are not aware whether white mice or any other mice frequently contract jungle fever. Choice E would not weaken the argument but strengthen it instead.
E
The conclusion that some element present in serum D causes jungle fever would be greatly strengthened if the element and the fever were invariably found together, as stated in choice C. Choice D doesn’t in any way establish the cause of the high rate of jungle fever in the group. Choice B would weaken the argument instead of strengthening it. The choices A and C would neither weaken nor strengthen the argument.
C
In this discussion, the first sentence declares the conclusion ; the second sentence states the evidence. But, there is no real connection between these two statements unless the postulate given in choice C is accepted as valid.
E
The first statement is not appropriate as we are Statement I is an inappropriate response, since we are keen to evaluate the objection, and not in the conditions under which the person arrived at it. The second statement is appropriate, as if the weak will be miserable come what may, then war at the universal level will increase the number of happy people and not increase the number of miserable people. The third statement is also appropriate as the strong are frustrated, and it is accepted that the weak are miserable (as they cannot adjust to the environment), no one is happy. If war at the universal level can make some people happy, then it is justified by the rule quoted in the passage.
A
The second statement could be permitted by the author in the first place, as the weak are weak by virtue of their limited capacity to adjust to the environment, and hence war at the universal level would only quicken their demise. The third statement would not weaken the discussion as the issue is not their mere survival but their happiness. The first statement would weaken the discussion as we could possibly develop an environment to which the weak could readily adapt, and then by definition they would no longer be weak.
A
To complete the passage we need a phrase, which describes the natural beauty of America not seen in the urban areas. Choice C would be inappropriate as it talks of the wild jungles of Africa, whereas our concern is the United States.
