Question

high - speed rail systems, in which trains can move at great speeds, are expanding in many countries because high - speed rail can reduce the number of automobiles on the road and ultimately conserve energy. in morocco, for instance, 186 kilometers of high - speed rail lines are in operation as of 2023, and 1,287 kilometers are under construction. which choice best describes the overall structure of the text? a) the text notes a general trend and then cites an example of that trend. b) the text summarizes an argument and then offers a challenge to that argument. c) the text questions a course of action and then suggests alternatives to that action. d) the text rejects a long - held belief and then proposes a different interpretation.

Explanation:

The text first presents a general trend (high - speed rail systems expanding in many countries to reduce cars and conserve energy), then gives an example (Morocco's high - speed rail lines in 2023). This matches the description in option A.

Answer:

A. The text notes a general trend and then cites an example of that trend.
