. By a vote of 9 to 0, the Supreme Court awarded the Central Intelligence Agency broad discretionary powers (enabling it to withhold from the public) the identities of its sources of intelligence information.
b) for it to withhold from the public.
Key: A
b)为什莫错？？作者: tongxun 时间: 2002-9-28 12:41
awarded sb sth 已经有for it 的意思了，再加上多余。若将B改写为下面的可能可取：
to ensure it to withhold form the public。

这里分词解释powers. 只能用 enabling, ensuring or that enables..
不能用不定试.
