National Zoo's

Expert replies

National zoos involved in modernization have found the local citizens are difficult to reach, taciturn and are suspicious of innovations.

(A) the local citizens are difficult to reach, taciturn and are
(B) local citizens to be difficult to reach, taciturn and are
(C) that local citizens are difficult to reach, taciturn and
(D) local citizens are difficult to reach, taciturn and are they are
(E) that local citizens are difficult to reach, and taciturn and they are

OA C

Source : Gmatclub forums

Doubt : though the C is the only correct option, but it also lacks a Main punctuation. As per the rule to list three items you use X,Y,and Z. There should be a comma before AND. However C doesnot employs any punctuation before AND and still correct.

to me it is a Run on Sentence. Because "taciturn and suspicious of teenagers are considered one entity" and then the form turns out to be X,Y, which itself is incorrect.

Please explain.??

It doesn't matter, you can write the sentence without the comma as well. I don't think it affects the sentence in meaning or in grammar.

when there is a list of items all the items in the list must play the same role (should be parallel that is all the items should be nouns or verb or ing form or to infinite).

have found demands "that"
Between C and E, they in E is ambiguous it could refer to zoos or local citizens. Hence C is OA.

The important aspect is to note how prepositions and verbs are placed in a parallel structure. For the case in question, it can be in the following formats.

a) Are difficult to X,Y and Z
b) Are difficult to X,to Y and to Z

Option C is the correct choice here.
