D. Daylight Savings Time was first implemented in Germany.

Correct answer: A

Rationale: The correct answer is A: "Daylight Savings Time helps save energy." The passage explains how Daylight Savings Time is implemented to take advantage of more daylight, which results in energy savings. By adjusting clocks ahead in spring, people can make use of additional daylight in the evenings, leading to reduced energy consumption.

Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits.

Choice D is mentioned in the passage but is not the main idea; the main idea is about the purpose and benefits of Daylight Savings Time.

2. What is the meaning of the word impoverished in the first paragraph?

A. Honored
B. Nobility
C. Rich
D. financially weakened

Correct answer: D

Rationale: The word 'impoverished' typically refers to a state of extreme poverty or being financially ruined.

Choice A 'Honored' is incorrect as it has a positive connotation opposite to the negative meaning of 'impoverished.' Choice B 'Nobility' is incorrect as it refers to a high social rank or class, which is unrelated to the financial state implied by 'impoverished.' Choice C 'Rich' is incorrect as it is the opposite of 'impoverished,' denoting wealth and abundance, not financial weakness.
