165 According to some analysts, (whatever its merits, the proposal to tax)away all capital gains on short term investments would, if enacted, have a disastous effect on Wall Street trading and employment.

应该选a没错，可是whatever its merits后面不应该有个谓语动词什么的？

158，Although it claims to delve into political issues, television can be (superficial such as when each of the three major networks )broadcast exactly the same statement from a political candidate.
e: superficial, as when  the three major networks each,
我不明白as 和when怎么可以连用，还有，three major networks each，可以么？复数词+ each?

请指教！
