Answer: 



6.       D    the adjective little modifies ‘ mass nouns” (e.g. water), refer to some undifferentiated Quantity; the adjective fey modifies “count nouns” (e.g... services), which refer to made up to distinct members that can be considered” Hence, choices A and B are incorrect because little properly modify services.
Also, since water and services are being discussed as a pair, they should logically be treated as a compound subject requiring a plural verb; thus, the singular exists (in B and C) is wrong.
Choice D is the best; the plural verb is used, and few correctly modifies services.

7.       C    The best choice is C.

Choices A, B and D present structures that are unwieldy and awkward in addition to being nonparallel, and they state the relationship between language use and skills development less clearly than C does.
Also, underlying in B is incorrect; the meaning of this sentence requires the present participle of ‘underlie, “underlying as, a modifier of skills.

8.       B   As the sentence is referring to two techniques which are used for similar things the word used should be ‘Like polio vaccine “which is only given in B.

9.       C   As the subject in the clause is “relations” which is plural, it has to be followed by “That illustrate.” Hence C.

10.   D    “Seemingly “(adverb) should be used with fashion (verb) and in the second part the phrase should be “targeted specifically at”. Hence d.
