Question

question 6
the article says:
the u.s. was nervous about the soviet uni (ussr).... the two nations didnt have a g relationship. as work went on, spies sent o about the project to the ussr.
in this passage, the word nervous means
a. to be calm
b. to be sorry
c. to be proud
d. to be worried

Explanation:

To determine the meaning of "nervous" in the passage, we analyze the context: The U.S. didn't want other nations (like the USSR) to learn about its project, and spies sent details to the USSR. This shows the U.S. was concerned/worried about the USSR. Option A (calm) is opposite, B (sorry) doesn't fit, C (proud) is unrelated. So "nervous" means "to be worried" as in D.

Answer:

D. to be worried
