A. Smoking as well as obesity are leading risk factors for heart attack

B. Smoking and obesity is leading risk factors for heart attack

C. Smoking as well as obesity are risk factors for heart attacks

D. Smoking and obesity are leading risk factors for heart attack

E. Smoking is the leading risk factor for heart attack as well as obesity


This is a SC Butler Question



OFFICIAL EXPLANATION



Smoking as well as obesity are leading risk factors for heart attack.


A. Smoking as well as obesity are leading risk factors for heart attack

This answer choice is stylistically flawed. Using as well as instead of and is redundant.

What helps us identify this mistake is the following Stop Sign:

    as well as



B. Smoking and obesity is leading risk factors for heart attack

This answer choice is grammatically incorrect. The plural subject smoking and obesity does not agree with the singular verb is.

What helps us identify this mistake is the following Stop Sign:

    A plural subject made up of singular nouns connected by and



C. Smoking as well as obesity are risk factors for heart attacks

This answer choice repeats the original redundancy: using as well as instead of and is redundant.

What helps us identify this mistake is the following Stop Sign:

    as well as

In addition, omitting the word leading results in some meaning loss.



D. Smoking and obesity are leading risk factors for heart attack

CORRECT


E. Smoking is the leading risk factor for heart attack as well as obesity

This answer choice repeats the original stylistic flaw of redundancy at a different place in the sentence. Using as well as instead of and is redundant.

What helps us identify this mistake is the following Stop Sign:

    as well as

Furthermore, moving the words as well as obesity to the end of the sentence changes the meaning of the original sentence.

In the original sentence, there are two causes - smoking and obesity - and one effect - heart attack.

According to this answer choice, there is one cause - smoking - and two effects - heart attack and obesity. Put differently, in this answer choice obesity is not a risk factor for heart attack, like smoking, but something that is caused by smoking, like heart attack.
