B. In his upcoming lecture in Prague, the tenured professor plans to speak on the damaging effects of melting ice caps, depleting water sources and oxygen levels, - Not parallel, WRONG

C. In his upcoming lecture in Prague, the tenured professor plans to speak on the damaging effects of melting ice caps as well as depleting water sources and oxygen levels, - Parallel - 'melting ____ as well as depleting ____' & 'water sources and oxygen levels' CORRECT

D. Damaging effects of melting ice caps are what the tenured professor speaks on in his upcoming lecture in Prague and also depleting water sources and oxygen levels,

Official Explanation:


it's not clear how the sentence should be corrected. The sentence is too long and complex to try and correct the original sentence, so we will have to use the answers. (D) and (E) use the present tense speaks when future tense is required. The phrase as well as in answer (C) is unnecessary, which leaves us with (A) and (B). In (A) for is the wrong preposition to follow to speak, as the professor is not speaking on behalf of someone or for the advocacy of something, but is speaking about something; therefore, the correct preposition is on, which means (A) is incorrect. (B) uses the correct parallel structure.

I got this incorrect. I chose C and thought it was the clear winner.

For B, I would like to know how this sentence creates parallelism. To me, I read the sentence as if depleting water sources as a participle modifier. Doesn't that change the meaning? Should it be damaging effects of melting ice caps AND depleting water sources (all of which are signs). Without a conjunction, it seems like the clause started by depleting is a modifier. That can't be right can it?

I'm curious why B is correct as well.

There is no AND before depleting.

I have already raised my hand for this question but I didn't get satisfactory answer.


Case- 1

...speak on the damaging effects of x and y.
x= melting ice caps
y= depleting water sources and oxygen level
This one need conjunction "and" before depleting.

Case- 2 (I think you applied this logic for B)
...speak on the damaging effects of x, y and z.
x= melting ice caps
y= depleting water sources
z= oxygen levels.

Now, I could not grab how z is parallel to x and y.
Please elaborate and help me.

As explained in OE - 'as well as' can not be used as marker for parallel list. that is why C is wrong.

Hello Sir!

I appreciate your response. But you are not addressing the concern I have raised in option B.
How X, Y, Z are parallel in case-2 as mentioned in my previous post.
I will be thankful to you if you explain it.
