Explanation:
Im taking the test right now
The purpose of this document include option: B) to examine the role of public transportation in conserving energy and reducing pollution.
What is the purpose of this document?
It is syntactically and semantically coherent. It precisely follows parallelism(plural form in 'federal subsidies..transportation systems and local efforts') that gives a clear and comprehensive meaning.
The other options are incorrect as they either contain parallelism error(inappropriate use of 'subsidizing' in option A) or unnecessarily uses the verb form('at persuading' in option B and 'making' in option C). Thus, option D is the correct answer.
Therefore, correct option is B.
