Critical Reasoning

the crux as i could understand is that
there would be more students preferring philosophy so the college is considering hiring new profs

nowhere is something about courses mentioned and making an assumption that the number of professors
decide the number of courses does not seem valid as thee still could be a 100 diff reasons why a course could or not be there

the college's aim is to attract students by taking in new prof
we need to doubt this idea in the Q
that could happen only if "even after hiring new profs students dont join the coll just bcoz they felt the prof were new and not that talented
which is given in E

can anyone justify B and also negate the E as the OA is E there should be some flaw in this reasoning
and ne power-score cr biblers here, can u classify this Q into any of the types given in that book

Which of the following would it be most useful for Inagua College
to know in evaluating the plan it is considering?

Can some one explain - what is the category of this question + what are the characteristics of this type of question

Thanks
