Excerpt from Conserving Energy and Preserving the Environment Bureau of Transportation Statistics: US D. O. T. 2 Our communities, the economy and much of our lives are organized around our ability to travel easily and efficiently from home to work or school, to shop or play, to receive medical care or just for the sheer pleasure of traveling. (1) This freedom has certain costs that accompany its many benefits. (2) Vehicles, public and private, have to be purchased and operated; (3) roads must be built and maintained; laws must be enforced so many people can travel at the same time; and (4) hundreds of thousands of accidents inevitably occur. Which sentence would BEST begin paragraph 2? A) Americans value freedom. B) Americans value their mobility. C) Americans are the victims of progress. D) Americans are able to afford large vehicles.

B) Americans value their mobility.

Explanation:

Mobility and its cost is the main concepts being talked about throughout the paragraph. The last part of the paragraph talks about the costs, we have to pay to afford this freedom of mobility. More over when we value something, we usually have to pay some cost. So starting the paragraph with "Americans value their mobility.", will be good start to let the readers know what is about to come in next lines.

A) Americans value freedom, will be very misleading, because it is freedom of mobility, not freedom in its conventional sense, which the paragraph/author is talking about.

C) Americans are the victims of progress will also be a bad start because, reader will infer that next few lines will try to prove that progress is bad for Americans.

D) Americans are able to afford large vehicles, would also be a misleading start because this does not signify the importance and cost of mobility.
