If S is a set of ten consecutive integers, is the integer 5 in S?
(1) The integer –3 is in S.
(2) The integer 4 is in S.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
为什么不能选C
因为4可以做成最后一个数字
从4往前数10个 -3也在
