What was the greatest difference between the high and low test scores of any particular student in the third grade at PS 11?

(1) The highest test score earned by any student in the third grade at PS 11 was 98. (2) The lowest test score earned by any student in the third grade at PS 11 was 44.

What was the greatest difference between the high and low test scores of any particular student in the third grade at PS 11? (1) The highest test score earned by any student in the third grade at PS 11 was 98. (2) The lowest test score earned by any student in the third grade at PS 11 was 44.

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.

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? _________________
