74 E5－9Intended primarily to stimulate family summer travel, the new airfare also shortens the advance-purchase requirement for family travel to a minimum of seven days rather than fourteen.
这里，rather than 后面不加 that of，刘振民上说，that 指代 a minimum，前面还需要加 to 来保证平行。请问为什么一定要加to 呢？省略介词不是一样可以平衡吗？
回复：不加介词虽然可以平行，但是往往会引起歧义（即并列成分有误），加介词就是为了保证平行结构意思的单一性

No less remarkable than the development of the compact disc has been the use of the new technology to revitalize, in better sound than was ever before possible, some of the classic recorded performances of the pre-LP era.
原句（A选项）是What was as remarkable as the development of the compact disc，OG上的分析是说时态错误。如果忽略这个错误，A选项正确吗？As remarkable as 和 no less remarkable than 可以做同等意思处理吗？另外，这句话从in better sound 往后就看不懂了，请教一下，是什么意思啊？
回复：先别看插入语，读SC时，先抛弃一切可弃成分，抓主干，看不太懂也照样能做对。解释一个名词pre-lp era 所谓LP就是LONG-PLAY技术，即长时间播放功能，当然得降低音质为代价，MD，CD上都有，你可看到。

Intar, the oldest Hispanic theater company in New York, has moved away from the Spanish classics and now draws on the works of contemporary Hispanic authors, both those who live abroad and those who in the United States.
选项E是 draws on the works now of both contemporary Hispanic authors living abroad and those，OG的解释是 both 这里修饰contemporary Hispanic authors living abroad 而导致逻辑错误，可为什么不可以把它也看作是 both.. . and … 的句型呢？然后those指代contemporary Hispanic authors？逻辑上也合理呀。
OG 222
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选项是，for it to withhold from the public，for it 为什么不对呀？
我觉得是意思上重复，属于redundancy的表达，因为不用for it意思上已经很明白是授权CIA怎么样。
