答：这是一道搞脑子的坏题.题目本身改编得不好,答案又不唯一.
首先这句尾的问号就莫名其妙!这又不是疑问句!哪来的问号?是的,as to后跟的是一个由问题变过来的名词性从句,可以是as to the question who/which .,Bob or Jim.但是有了Bob or Jim这选择后,没有问句,好象又不妥.
其实本来不需要这个选择的,改为
Bob and Jim usually receive the same score on standardized exams,so there is often disagreement as to who is better.
原题纯粹是“人工考句”!
我找到了它的祖上：
50个最容易出错的英语语法题
12,(There is ) often disagreement( as ) (to whom) is the (better) Shakespearean actor,Evans or Gielgud.
BBBBD/ADCAB/
CCBCC/BABBD/
这题可以,因为四个中,就C.to whom是错的.
所以在改编题目时,应避免who与which同时出现.
当然,who可能比which更好些.因为which常指事物.但是在两个人中进行选择时,可以用的.网上有一模一样的疑问句：
Which is the better student?
A.
Straight A and A* student with 1 B grade
Going to the fifth best college in the UK.
Studying:
Biology AS (strong to very strong course)
Theology AS (Philosophy and Ethics) (strong course)
English Language and Literature (Combined) AS (strong course)
Psychology AS (average course)
B.
Straight B student with a couple of A's.
Going to about the 30th best college in the UK.
Studying:
Graphics AS (very weak course)
Geography AS (average to strong course)
Maths AS (Strong course)
Psychology AS (average course)
Weak course - Soft subject that universities look down upon.
Average course - Universities like the course but it limits the student to what choices they have.
Strong course- A course very respected by universities across the country.

@leigh If your answer stems mainly from person's B choice of the art-based subject,Graphics,then I would like to add that person A and person B both do Graphics at high school but person B gets a C/D in the subject whereas person A gets a B grade.In addition,English Language/Literature is a language art course.

@Daniel The only good subject that student B has chosen is Mathematics A level!The others are weak subjects that universities look down upon or limit the student's choice of degree course.And tell me how B's are equal to A's and A*'s?

@Daniel How is Biology the lesser science and for English Literature students?!Sure it is the easiest A level out of all three sciences but without Biology the world would be in a mess.All sciences are just as important as each other.Physics isn't the 'best' science because all science is essential in the modern world.
