Greenhouse Effects

[Dean Jones]

Dear Friends,

I'm having problems in answering the following question. Please help.


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

OA after some discussions.

Regards
Deano.

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

do not find any issue with this sentence. "and those that would have the largest impact on people" - clearly acts as a modifiers of EFFECTS

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

ambiguity on THOSE - does it refer to EFFECTS OR 'EXTREMERS OF...'. The sentence changes the emphasis from "extremes of temperature, precipitation, and storminess (as in original sentence)" to
"impact of people". Secondly, original sentence says 'largest impact on people' while B says 'impacting the most' - IMO they intent say convey different meaning (but not very sure about the meaning of these 2 phrases)

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

Changes the possibility (WOULD) to certainilty (by using TO HAVE & ARE). Its also not clear whether "extremes of temperature, precipitation, and storminess" are part of the same list. Are they 'extremes of temperature, extremes of precipitation, and extremes of storminess' or just "extremes of temperature, precipitation, and storminess".

D. extremes of temperature, precipitation, and storminess, the most obvious effects, that they would have the largest impact on people

Placement of modifier "the most obvious effects" (a noun modifier here) is such that it modifies 'storminess' only. Ambiguity on THEY - "EFFECTS/EXTREMERS OF...".

Secondly, this sentence is a fragment - no verb attached to the clause 'extremes of temp...'

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

Which refers to STORMINESS. Changes the possibility (WOULD) to certainilty (by using ARE).

IMO A

yup A seems to be the best answer......
