Correct answer: A

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. This measure was introduced to address energy crises and has been shown to save significant amounts of energy. Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits. Choice C is partially correct but not the main idea of the passage, as saving energy is the primary focus. 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.

3. The passage mentions all of these uses for microscopy EXCEPT ___________.

A. Ear surgery
B. Amputations

D. Reconstructions

Correct answer: C

Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text. Therefore, vasectomies are the exception among the listed uses. Choices A, B, and D are supported by details in the extract, making them incorrect answers. The passage highlights the uses of microscopy in delicate ear operations, repairing blood vessels in partially amputated limbs, and improving breast reconstructions. While vasectomies are mentioned briefly in the extract, they are not connected to the application of microscopy in the context of surgeries.

The passage explains how the suits of cards, such as spades, hearts, diamonds, and clubs, are used in the game of Bridge. Choice A, 'A set of clothing,' is incorrect as it does not relate to the context of playing cards.
