If v and w are different integers, does v = 0 ?
(1) vw= v2
(2) w = 2
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.
(1) v(v-w)=0, v与w不相等,v等于0
(2) w=2, v可以为任意其他整数
