Professor Knight has noticed that students who guess on her multiple-choice tests are significantly more likely to choose answer choice C instead of A, B, D, or E. Basing her judgment on the fact that a variety of students from different social groups and backgrounds all do this, she has concluded that this tendency was acquired from her colleague Professor Leigh's habit of predominantly using C as a correct answer choice, rather than students' natural tendency to choose the middle letter. Professors Knight and Leigh are the only professors who give multiple choice tests in the required classes of the first and second year.

Which of the following, if true, would most strengthen the conclusion drawn by Professor Knight?

A) She has noticed that students tend to choose C only at her current school, rather than having noticed this tendency throughout her career.

B) Professor Knight’s first-year students do not pick C more than any other letter, but her second-year students, who have all taken the same required classes, do.

C) Professor Leigh has a similar theory and believes that Professor Knight is the cause.

D) The students are required to take the same classes during their first year, but, with the exception of one required lecture, can choose their electives during their second year.

E)Previous students who learned test techniques from Professor Leigh applied these techniques to tests in Professor Knight's class

This question is a good example in which because of other reasons, options cannot be the strengthener. However, I am still unconvincing with OA/

IMO OA is B.

I think the important sentence is below.

'Professors Knight and Leigh are the only professors who give multiple choice tests in the required classes of the first and second year.'

I was confused between B and E, but I chose B.
In E, there is no mention about first and second year.
Then we can infer that professors Knight has classes of the 4th year. So I removed this and chose B.

Stem - Professor Knight believes - Students choose C option because of her colleague Professor Leigh's habit of predominantly using C.
Professors Knight and Leigh are the only professors who give multiple choice tests in the required classes of the first and second year.

A - though this option is relevant, No information provided that it is caused by Professor Leigh's habit.
B - Professors Knight and Leigh are the only professors who give multiple choice tests in the required classes of the first and second year and student start to chose C more in the second year or so. Supports that Students came to know about Professor Leigh's habit of predominantly using C and start using it afterward.
C - Professor Leigh has a similar theory and believes that Professor Knight is the cause. - Out of scope - what Professor Leigh thinks
D - The students are required to take the same classes during their first year, but, with the exception of one required lecture, can choose their electives during their second year. - Out of scope. No mention of multiple choice questions.
E - Previous students who learned test techniques from Professor Leigh applied these techniques to tests in Professor Knight's class - Talks about test techniques but not about multiple choice questions. So can't use this information to support the stem.
