GWD 24-23

24-23 Discussion of greenhouse effects has usually focused on
whether the Earth would warm and by how much, but climatologists have
indicated all along that the most obvious effects, and those that
would have the largest impact on people, would be extremes of
temperature, precipitation, and storminess.

A) the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess.

B) the effects that are the most obvious ones, extremes of temperature, precipitation, and storminess, would be those impacting the most on people.

C) those effects to have the largest impact on people, extremes of temperature, precipitation, and storminess, are what are the most obvious effects.

D) extremes of temperature, precipitation, and storminess, the most obvious

effects, that they would have the largest impact on people.

E) extremes of temperature, precipitation, and storminess, which are the most obvious effects, are those to impact the most on people

答案是A还是D?

I would choose A

B/c Discussion of greenhouse effects... but climatologists have indicated.... the most obvious effects...would be

the transition is more smooth here

请问红色字部分在这里做什么成份呢？谢谢～～～

"and those that" 看着有点别扭，是effects得同位语嘛？

why not B????
