For the students in class B, the range of their heights is s centimeters and the greatest height is h centimeters. Is the least height of the students in class A greater than the least height of the students in class B?

(1) r < s

(2) g > h

(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

(C) BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

(D) EACH statement ALONE is sufficient.

想请问这题里面的range是什么意思？是不是极差？就是最大值减去最小值的差？
