A. Student A's test scores are the highest in her class.
B. Before the previous test, the two students had covered only two thirds of the material.

D. Sleep deprivation is known to negatively affect test performance.
E. The last test also took place at 8 AM.

OFFICIAL EXPLANATION
Student A: We have a big test at 8 AM tomorrow. Before our last test, we went to bed early, had a good night's sleep and did really well on the test. I suggest we do the same tonight.
Student B: We still need to cover a third of the material. We will finish at 3 AM. Then we can go to bed.
Which of the following, if true, most supports Student B?
A. Student A's test scores are the highest in her class.
Incorrect.
This is a Conclusion Strengthening question in the Dialog format. You are asked to choose the answer choice which strengthens Student B's conclusion (or weakens Student A's conclusion):
This answer choice neither supports nor weakens Student B. The fact that Student A's test scores are the highest in her class does not support staying up until 3 AM to cover all the material; on the other hand, it doesn't mean she will not fail this test.
B. Before the previous test, the two students had covered only two thirds of the material.
Incorrect.
This answer choice weakens Student B's conclusion indirectly, by strengthening Student A's conclusion. If the two students covered only two thirds of the material before the last test and still did well on it, they can probably do well on this test as well with the same amount of coverage. This means that they do not need to do as Student B proposes and study until 3 AM to cover the remaining third of the material.
C. Before the previous test, the two students had covered all the material for the test.
This answer choice strengthens Student B's conclusion by revealing that the success in the previous test could have been due to studying well, rather than sleeping well. This both stresses the need to study well and somewhat undermines the necessity of sleep.
D. Sleep deprivation is known to negatively affect test performance.
Incorrect.
This is a Conclusion Strengthening question in the Dialog format. You are asked to choose the answer choice which strengthens Student B's conclusion (or weakens Student A's conclusion):
This answer choice weakens Student B's conclusion by showing that going to sleep late and getting less than 5 hours of sleep may have adverse effects on the students performance in tomorrow's test.
E. The last test also took place at 8 AM.
Incorrect.
This answer choice neither supports nor weakens Student B. The fact that the last test also took place at 8 AM does not support one proposed course of action over the other.
