(A) the protein in rice is higher quality than that in

(C) the protein in rice is higher in quality than it is in
(D) rice protein is higher in quality than it is in
(E) rice has a protein higher in quality than

The first part of this sentence sets up a comparison.

When we get to the comma, we should STOP and ask the question that the introduction raises.

So, once we read, In addition to having more protein than wheat does, we should stop and ask . . .

"Who or what has more protein than wheat does?"

If the sentence is properly constructed, the part that immediately follows the comma will answer that question in a logical manner.

Reading on we get...

A) the protein in rice...
What? The protein (in rice) has more protein that wheat does?
Makes no sense.
ELIMINATE A

B) rice ....
So rice has more protein that wheat does.
This makes sense.
KEEP B

C) the protein in rice...
The protein (in rice) has more protein that wheat does?
Makes no sense.
ELIMINATE C

D) rice protein...
Rice protein has more protein that wheat does?
Makes no sense.
ELIMINATE D

E) rice ....
So rice has more protein that wheat does.
This makes sense.
KEEP E

We're down to B and E
B) rice has protein of higher quality than that in
The word that properly serves as a placeholder for protein
In other words, rice has protein of higher quality than the protein in wheat...
PERFECT!

E) rice has a protein higher in quality than wheat
This is a faulty comparison
It suggests that rice PROTEIN is better than WHEAT.
The intended meaning is that rice PROTEIN is better than wheat PROTEIN.
ELIMINATE E

Answer: B
