The essay focuses on presenting factual information and recent discoveries regarding the impact of microbes on human health. The author aims to educate the readers on the significance of microbes in human health rather than persuade them of a particular viewpoint (Choice A), entertain them with light-hearted content (Choice C), or analyze in-depth data and findings (Choice D).

2. What is the best title for the passage on bicycles?

A. Bicycles Are Better.
B. Cycle Your Way to Fitness.
C. A Ride through the History of Bicycles.
D. The Popularity of Bicycles.

Correct answer: C

Rationale: The correct answer is C: 'A Ride through the History of Bicycles.' This title best captures the passage's focus on the historical development and evolution of the bicycle from its invention to its modern form. Choice A, 'Bicycles Are Better,' is too general and doesn't encompass the historical aspect discussed in the passage.

Choice D, 'The Popularity of Bicycles,' touches on one aspect but does not encompass the comprehensive historical journey presented in the passage.

A. “Everyone Should Run Barefoot”
B. “How to Prevent Running Injuries”

Rationale: The title "The Debate over Barefoot Running" encapsulates the central theme of the passage, which explores both the advantages and disadvantages of barefoot running.

Other titles do not accurately reflect the primary focus of the essay, making D the most suitable choice.
