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 denmark, for instance, 56 kilometers of high - speed rail lines are in operation as of 2023, and 717 kilometers are under construction. which choice best describes the overall structure of the text? a the text rejects a long - held belief and then proposes a different interpretation. b the text questions a course of action and then suggests alternatives to that action. c the text summarizes an argument and then offers a challenge to that argument. d the text notes a general trend and then cites an example of that trend.

Explanation:

The text first presents the general situation of high - speed rail systems (expansion and energy - conserving benefits). Then it gives an example of Denmark's high - speed rail situation. This follows the pattern of noting a general trend and then citing an example of that trend.

Answer:

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