[piggy386]

I would like to know whether the correct answer is choice B or choice D.
Can someone please help me on this?

Sentence Correction:
With its abundance of noun inflections, Icelandic is one of several Germanic languages that is compact when written but can lengthen considerably when translated into English.
a: is compact when written but can lengthen considerably when translated into English
b: are compact when they are written, but they can lengthen considerably when they are translated in English.
c: is compact when written but can lengthen considerably when being translated into English.
d: are compact when written but can lengthen considerably in English translation.
e: is compact when it is written but can lengthen considerably when translated in English.

Should I assume the general pattern be "SINGULAR NOUN of NOUNS that PLURAL VERB"?
Or the correct form should be singular verb???

I remember if the pronouns are "Some, Any, None, All, Most", then I need to look at the object of the "of" construction to determine the number of the subject.

Ex:
Some of the money was stolen from his wallet.
Some of the documents were stolen from his locker.

I can't recall what to use when it comes to a numerical pronoun.
Please advise.
Thanks.
