Is x between 0 and 1 ?

(1) x2 is less than x.

(2) x3 is positive.

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.

考题讲解

（1）    如果x≥1，则~$x^2$~≥x，不满足条件1；如果x≤0，则~$x^2≤x$~，不满足条件1；如果0<x<1，则满足~$x^2<x$~，满足题目，所以根据条件1可以判断0<x<1。

（2）  ~$x^3$~  是正的，x可以是任意大于0的数，并不能说明0<x<1，不满足要求。
