Read the excerpt from The Dark Game: True Spy Stories from Invisible Ink to CIA Moles by Paul Janeczko.

The United States wanted desperately to know what the Soviets were thinking. The big fear for the U.S. was that the Soviets would attack West Germany without warning, or in diplomatic language, with "a cold start." The U.S. knew that the Soviets possessed nuclear weapons. Would they use them on the West? This question and others would need to be answered by U.S. intelligence agents.

Janeczko includes a question in the passage to

A. determine reader opinion.
B. inquire about personal experiences.
C. illustrate the Soviets' confusion.
D. voice the U.S. leaders' uncertainty.
