OA: E

What is the grammatical construction of E?

once ....., it will .... and ....

I go with E.

A: Like any weather pattern of similar virulence would do, once an El Nino affects water temperature in the Pacific Ocean, it threatens drought in the western Pacific, eventually dumping --incorrect compariosn using like. Like cannot be followed by clause
B: Like any weather pattern of similar virulence, once the water temperature in the Pacific Ocean is affected by an El Nino, then it threatens drought in the western Pacific and eventually dumps --modifier issue, weather pattern should mdify el nino
C: As in the case of any weather pattern of similar virulence, once the water temperature in the Pacific Ocean is affected by an El Nino, it will threaten drought in the western Pacific, and eventually dumping --same as B
D: As any weather pattern of similar virulence would, once the water temperature in the Pacific Ocean is affected by an El Nino it will threaten drought in the western Pacific and will eventually dump --Same as B
E: As would be the case with any weather pattern of similar virulence, once an El Nino affects water temperature in the Pacific Ocean, it will threaten drought in the western Pacific and eventually dump --though wordy, it is the best of the rest. this sentence sorts modifier issue, maintains parallelism

Like any weather pattern of similar virulence would do, once an El Nino affects water temperature in the Pacific Ocean, it threatens drought in the western Pacific, eventually dumping excess precipitation in the eastern Pacific.

A: Like any weather pattern of similar virulence would do, once an El Nino affects water temperature in the Pacific Ocean, it threatens drought in the western Pacific, eventually dumping: Like introduces a clause
B: Like any weather pattern of similar virulence, once the water temperature in the Pacific Ocean is affected by an El Nino, then it threatens drought in the western Pacific and eventually dumps since the introducory modifierr beginning with Like modifies water temprature, the sentence basically compares water temprature and weather pattern. Moreover, it seems ambiguous and at best wrongly referring to water temprature, the subject of previous clause
C: As in the case of any weather pattern of similar virulence, once the water temperature in the Pacific Ocean is affected by an El Nino, it will threaten drought in the western Pacific, and eventually dumping: same as B
D: As any weather pattern of similar virulence would, once the water temperature in the Pacific Ocean is affected by an El Nino it will threaten drought in the western Pacific and will eventually dumpsame as B
E: As would be the case with any weather pattern of similar virulence, once an El Nino affects water temperature in the Pacific Ocean, it will threaten drought in the western Pacific and eventually dump looks good

Hi Stacey,

Thanks for your reply.

I still have a doubt.

As would be the case ..., once an El Nino affects ..., it will threaten drought ...

I can see that every parts has a verb.

As would be the case ... => I am OK
once an El Nino affects ... => "affects" is a verb. Is it a main clause or modifier.
it will threaten drought ... => "will" is a verb. It seems to be main clause.

What is modifier and what is main clause? I confused because of "once ..."

Generally, AFFECT is a verb, and EFFECT is a noun.

C: As in the case of any weather pattern of similar virulence, once the water temperature in the Pacific Ocean is affected by an El Nino, it will threaten drought in the western Pacific, and eventually dumping: same as B
D: As any weather pattern of similar virulence would, once the water temperature in the Pacific Ocean is affected by an El Nino it will threaten drought in the western Pacific and will eventually dumpsame as B
E: As would be the case with any weather pattern of similar virulence, once an El Nino affects water temperature in the Pacific Ocean, it will threaten drought in the western Pacific and eventually dump looks good

If we write C as,
As in the case of any weather pattern of similar virulence,once an El Nino affects water temperature in the Pacific Ocean, it will threaten drought in the western Pacific and eventually dump
In case of D
As any weather pattern of similar virulence would,,once an El Nino affects water temperature in the Pacific Ocean, it will threaten drought in the western Pacific and eventually dump
In E
E: As would be the case with any weather pattern of similar virulence, once an El Nino affects water temperature in the Pacific Ocean, it will threaten drought in the western Pacific and eventually dump
