Plants are more efficient at acquiring carbon

Post Wed Nov 10, 2010 8:40 am
18. Plants are more efficient at acquiring carbon than are fungi, in the form of carbon dioxide, and converting it to energy-rich sugars.

(A) Plants are more efficient at acquiring carbon than are fungi,
(B) Plants are more efficient at acquiring carbon than fungi
(C) Plants are more efficient than fungi at acquiring carbon
(D) Plants, more efficient than fungi at acquiring carbon
(E) Plants acquire carbon more efficiently than fungi














OA is C
But what's wrong with A?? I don't understand the OE.(OE:According to the sentence grammar, in the form of carbon dioxide describes fungi, which is nonsensical)

I found no differences in A and C with this modifier. Hope any experts can explain it.

A WRONG for two reasons:

"Plants are more efficient than fungi" is sufficient.

You should repeat the verb if any one of the following is evident:
1. It creates ambiguity without the verb.
Example:
I like X more than Y.
-> it has two meaning without the verb.
1.1. => I like X more than Y does. [More than Y like X]
1.2. => I like X more than I like Y.

2. If there is a tense shift.

Example:

The sales figure is 10% more than it was in 2000.

COMMA + Modifier:
=> The modifier after comma Modifies the NOUN immediately before comma.
Example:

They have done the work, in a very efficient way.

==> The work is modified by efficient way.

The same deal is here.
In Choice A, do you think we should put the verb after the fungi if the verb need to be kept? Or I miss some points about inversion? Can you explain more?
Thanks in advance!
