Yeah, (B) is on the right track but way too strong. Perhaps someone who is kooky from 2 days of sleep deprivation isn't a great judge of anything; perhaps some sleep scientist would be more accurate in assessing the overall effects on that sleep deprived person.
(A) is saying that the subjective (i.e. "internally perceived") effects of sleep deprivation are stronger than the overt (i.e. "outwardly perceived") effects.
What does the Question Stem tell us?
Inference (Most Strongly Support)
Break down the Stimulus:
Read for Conditional, Causal, Comparative, or Quantitative language.
This one seems to have some Causal and Comparative in it. On one hand, losing sleep makes this professor feel like a worse teacher (causal). Meanwhile, (contrast) the students can't tell which sessions the professor was "off".
Any prephrase?
I'd anticipate some weakly worded, safe way of straddling that contrast, something like "self-perceived differences in mood or performance are not always perceived by others"
Answer choice analysis:
A) New Comparison. Subjective is MORE PRONOUNCED than overt? However, this does speak to the contrast between the teacher FEELING off and the students not noticing overt differences. Maybe.
B) "No one" is way too extreme.
C) New comparison. Professors vs. other jobs?
D) New comparison. "Occasional" vs. "extended"?
E) Extreme. Students "tend to" be astute? This goes against the gist. It seems like the students did NOT astutely observe that the professor was feeling off.
The correct answer is A.
Takeaway/Pattern: Our best defense on Inference questions (LR and RC) is a suspicious feeling any time we see STRONG wording or COMPARATIVE wording. We have to be able to justify the strong or comparative wording based on what we were told. The friction point in this fact set is the "interestingly" ... it sets up the contrast between the professor's self-perceptions and the students perceptions of her.
