1. Not Sufficient. Gives the hightest score of any student but doen't say anything about lowest score of that particular 'any student' 2. Not Sufficient. Gives the lowest score of any student but doen't say anything about hightest score of that particular 'any student' 1 & 2 together Not sufficient It's not clear that hightest and lowest score mentioned in statement 1 and 2 are of same student or of two different students. I pick E

1. Not sufficient
as we dont know anything about the low scores.
2. Not sufficient
as we dont know anything about the high scores
together , its still not sufficient
without knowing individual students maximum and minimum, its not possible to find out the difference. hence not sufficient.
Answer is E.

Hi All - I got C. Here was my reasoning:
It asks for the "greatest difference" of any specific student. When I see greatest difference I see largest difference possible. And the largest possible difference = highest score in class - lowest score in class. And when I see "particular student" I see any possible student. While the assumptions do not specify who received those scores, I don't think that is what the question is asking.
I guess the main thing is I am interpreting the question differently - Am I wrong here?

@stompy I will try to explain: Suppose there are 3 student in class. YOU, ME and C. You scored highest=98 Me scored lowest=44 C scored = 50. You and Me are picked. Greatest difference will be => 98-44= 54. but suppose You and C are picked. In that case greatest difference will be => 98-50= 48 we don't know two things 1)how many students are there? 2)which two are picked?

Yes, that makes sense. However the question states for a "particular student", not students. I thought we were comparing the scores for one student?

Yes we are but which one? You Me or Me or C or You or C? Question doesn't mention that. So its not sufficient to answer.
