求助一道数学题

The range of the numbers in set S is x, and the range of the numbers in set Tis y. If all of the numbers in set Tare also in set S, is x greater than y ?

(1) Set S consists of 7 numbers

(2) Set T consists of 6 numbers

• AStatement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
• BStatement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
• CBOTH statement TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
• DEACH statement ALONE is sufficient.
• EStatements (1) and (2) TOGETHER are NOT sufficient
• 这题正确选E，我选的是C。我想问的是，题中指的greater than 只是指大于吗？
• 所以等于的话就不算greater than，所以这题可能等于，也可能大于，所以答案不唯一，所以推不出来，所以选E吗？
• 是我理解的这样吗？
• 麻烦大家帮忙解答，谢谢啦
