IMO E seems good o me except the which part.. but "are" indicates that which is for the effects..

Choosing between A and E, i would stick with A since to impact the most on people is grammaticaly wrong. To impact someone and to have an impact on something/someone are correct uses.

I'm not seeing any error in the sentence itself (A). My answer would be A.
What's the OA and OE?

A sounds right.
Impact on people is correct idiom.

Construction in E is awkward - to impact the most on people

I think A is correct, but it's hard for me to explain the problems with B through E.

Since the poster has not posted the OA (after 22 days!), I found the original paragraph in a 1995 New York Times article http://www.nytimes.com/1995/05/23/scien ... ffect.html (see the 6th paragraph).
It confirms A, but I don't know if that's GMATically correct.

You have heard about the ecological consequences of the Greenhouse Effects for over 10 years; there are new reports on almost a daily basis concerning the Greenhouse Effect. If you examine these reports, the primarily discuss the impact on the environment from a human perspective or the impact on animals. One major component of the Greenhouse Effect is an increase in carbon dioxide in the atmosphere; carbon dioxide is considered a "greenhouse gas".

Why might the Greenhouse Effect be beneficial for plant life? Please Explain. Thanks.

Choosing between A & E, but chose A - E is kind of awkward.

Hi E-GMAT,
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.

Could you please explain Choice A & B.

My Analysis, the noun phrase "extremes of temperature,
precipitation, and storminess," should come in between the modifier.

Thanks

My views: (I would love to know E-Gmat Experts opinion on my analysis)

Meaning : Discussion of Greenhouse effects usually focus on whether Earth would warm. If yes, then how much? However, climatologists have indicated since long that most obvious effects of greenhouse would be extremes of temperature, precipitation, and storminess. Such effects would have largest impact on people

Discussion of greenhouse effects (Subject) has (Verb) usually focused on whether
the Earth (Subject) would (verb) warm and by how much, but
climatologists (Subject) have (verb) indicated all along that the most obvious effects (Subject), and those
that (subject) would have (verb) the largest impact on people,
would (Verb for "effects")be extremes of temperature, precipitation, and storminess

Sentence with option B

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

Meaning of option B : Discussion of Greenhouse effects usually focus on whether Earth would warm. If yes, then how much? However, climatologists have indicated since long that effects would be impacting most of people. Such effects are most obvious effects, extremes of temperature, precipitation, and storminess.

Option B states a different meaning. Also use of "impacting" is not correct.

Hope this helps

Hi there,

Option B changes the intended meaning significantly. Notice what the original sentence says, and how it uses "would".

The sentence uses "would" to indicate what the most obvious effects would be. "The most obvious effects... would be extremes of temperature, precipitation, and storminess."

However, in option B, the placement of "would" -- and thus, the meaning it indicates -- has changed. This option says that "the effects... would be those impacting." So, this option is using "would" to refer to the impact of the effects, whereas the original uses "would" to identify what the effects would be. I hope this distinction in meaning is now clearer.

Regards,
Meghna
