B) to destroy or damage property, and is primarily determined from wind speed; a category 5 storm has wind speeds high enough
"Determined from" is wrong

Please post you comments

I think that the correct answer is D. A,C and E are wrong because the corect idiom is "as high as", so "so high as" is wrong. Between B and D: we have "determined from" vs "determined by". The correct idiom is "determined by", so D is ok.

vbalex,

you're right. The correct idiom is "determimed by". I just looked it up in my Manhattan SC Guide. I was thinking there was a difference in usage of "determined from" and "determined by" and there doesn't appear to be. +1 for you.

The OA is D.

The issue here I think was between D. "wind speeds high enough" - used when X is the criteria by which an ability to measure Y is measured

E) "so high as" = indicates characteristic X is so extreme that y results.

Thanks for all your explanations.

“Determined by” is right; “determined from” is wrong
“so high as to” is preferred over “high enough to”, because “so high as to” means the storm is EXTREMELY high to cause those damages.
“Potential of” is better than “potential to”.

A) of destroying or damaging property, and is primarily determined from wind speed; a category 5 storm has wind speeds so high as
-- WRONG: “determined from” is wrong, “so high as” is wrong.

B) to destroy or damage property, and is primarily determined from wind speed; a category 5 storm has wind speeds high enough
-- WRONG: “determined from” is wrong

C) of destroying or damaging property, and is primarily determined by wind speed; a category 5 storm has wind speeds so high as
*** BEST ANSWER

D) to destroy or damage property, and is primarily determined by wind speed; a category 5 storm has wind speeds high enough
-- WRONG: “high enough” is not as good as “so high as”.

E) to destroy or damage property, and is primarily determined by wind speed; a category 5 storm has wind speeds so high as
*** WRONG: “to destroy” is not as good as “of destroying.

B and D are good candidates.

Personally, B and D are passive and we are coordinating two sentences with different voices (First concern). However, D seems more intriguing since it employs correct idiom.

Allen,
Split the setence D into two parts.

"The category 1 to 5" ..provides estimate....
and
The category 1 to 5" is determined by windspeed. (Doesn't this looks like passive voice..???)
Windspeed determines The category 1 to 5 (Active voice)

I agree that the middle "is primarily determined...." is passive, but that's just 1 section out of what I see as three different parts. I guess it take more than this for me to classify a sentence as passive. Maybe I'm wrong.

why so high as to is wrong here?

I think the author means the wind speed is so extremely high to ...

of destroying is correct usage ,A Vs C , determined by is correct
