Simple and good question - after "and" .. ", as source of building .., " confused me , Then I realised it is modifier and can be ignored ...

So answer is E parallelism - supply and provide

87. While they remove carbon dioxide from the air, conserve soil and water, and house thousands of species, forests also supply potentially valuable pharmaceuticals, and, as sources of building material and firewood, that provide employment for millions worldwide.
A. pharmaceuticals, and, as sources of building material and firewood, that provide - comma twice looks awkward, 'that' changes the meaning
B. pharmaceuticals, and sources of building material and firewood, are providers of - comma after pharmaceuticals is ambiguous
C. pharmaceuticals and, as sources of building material and firewood that are provide - that are provide?
D. pharmaceuticals and as sources of building material and firewood, for providing - for providing?, also you need comma after 'and'
E. pharmaceuticals and, as sources of building material and firewood, provide - makes most sense

+1 E

This sentence requires parallelism for the verbs: supply and provide (both have to be working verbs).

forests supply and provide. So E contains this and should be the correct answer.

E for me too....
We cannot have comma before 'and'.... This will eliminate options A and B...
C has the incorrect usage 'that are provide'...
D is incorrect because of "for providing"... supply has to be parallel with provide...

Left with E....

87. While they remove carbon dioxide from the air, conserve soil and water, and house thousands of species, forests also supply potentially valuable pharmaceuticals, and, as sources of building material and firewood, that provide employment for millions worldwide.

A. pharmaceuticals, and, as sources of building material and firewood, that provide
B. pharmaceuticals, and sources of building material and firewood, are providers of
C. pharmaceuticals and, as sources of building material and firewood that are provide
D. pharmaceuticals and as sources of building material and firewood, for providing
E. pharmaceuticals and, as sources of building material and firewood, provide

I think this particular problem is more related with the meaning of the sentence.

Forests supplies pharmaceuticals.
and 'as sources of building material and firewood' forests provide employment for millions worldwide.

The above combination conveys the meaning clearly.

A. pharmaceuticals, and, as sources of building material and firewood, that provide
'and' creates a fragment sentence

B. pharmaceuticals, and sources of building material and firewood, are providers of
meaning distortion

C. pharmaceuticals and, as sources of building material and firewood that are provide
meaning distortion

D. pharmaceuticals and as sources of building material and firewood, for providing
parallelism, 'for providing' meaning distortion

E. pharmaceuticals and, as sources of building material and firewood, provide
correct

What do we mean here by saying we cannot have a comma before 'and' ?

I guess he meant that X, and Y is imprecise and that the correct structure should be X and Y. Well, I eliminated A because of 'that..'.

A. pharmaceuticals, and, as... firewood, that provide
Structure: Forests supply, and that provide - It's a sentence fragment. 'that' is missing an antecedent.


E. pharmaceuticals and, as...firewood, provide
Structure: Forests supply and provide - parallel

Hope it helps!

It is a Parallelism question.

Supply ..... and provide – correct parallism.

Now here, modifier is added with ‘,modifier, ‘

Thus, ‘comma after and’ is ‘not a part of and’ rather it is ‘a part of inroduction of the modifier’.

Hence, option E is the correc answer.

Primarily there are 2 usages of that:
1. As a Noun
2. As a connector.

1. As a Noun
Chairs that don’t have cushions are uncomfortable to sit on. Note that, here 'that' refers back to chairs. Because Chairs is a plural noun, you should use verb - do + not for a plural noun = Don't (and not doesn't)

2. As a connector
Eg. I believe that he is innocent.

Let me come back to the quetion:
While they (referring to forests) remove carbon dioxide from the air, conserve soil and water, and house thousands of species,

forests also

1. supply potentially valuable pharmaceuticals and (note here there are only 2 items in the list and hence we use just AND. We do not use comma + and)
2. provide employment for millions worldwide.

Now, 2nd act of providing employment has a modifier which is introduced by way of a phrase between two commas:
, as sources of building material and firewood,

Do not mistake to refer the first comma from modifier with and preceding that comma.

Key in solving SC question is Meaning (and not the grammar)!

A. pharmaceuticals, and, as sources of building material and firewood, that provide --> NOT PARALLEL
B. pharmaceuticals, and sources of building material and firewood, are providers of --->NOT PARALLEL; INCORRECT MEANING
C. pharmaceuticals and, as sources of building material and firewood that are provide ---> NOT PARALLEL
D. pharmaceuticals and as sources of building material and firewood, for providing -----> NOT PARALLEL
E. pharmaceuticals and, as sources of building material and firewood, provide ----> correct


Parallelism is at play here
Clearly the correct answer is E
