问题     This was before the steam locomotive, and canal building was at its height. The companies building the canals to transport coal needed surveyors to help them find the coal deposits worth mining as well as to determine the best courses for the canals. This job gave Smith an opportunity to study the fresh rock outcrops created by the newly dug canal. He later worked on similar jobs across the length and breadth of England, all the while studying the newly revealed strata and collecting all the fossils he could find. Smith used mail coaches to travel as much as 10,000 miles per year. In 1815 he published the first modern geological map, "A Map of the Strata of England and Wales with a Part of Scotland," a map so meticulously researched that it can still be used today.
According to paragraph 2, which of the following is true of the map published by William Smith?
选项 A、It indicates the locations of England’s major canals.
B、It became most valuable when the steam locomotive made rail travel possible.
C、The data for the map were collected during Smith’s work on canals.
D、It is no longer regarded as a geological masterpiece.
答案C
解析
