A. thwarted
B. forfeited
C. implemented
D. discharged
E. redoubled

Correct Answer: A

Explanation:

Explanation for Correct Answer A:

Choice (A) is correct. "Thwart" means to prevent or defeat. If one were to insert this term into the text, the sentence would read "Dangerously high winds thwarted attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The scheduled launch of the space shuttle was delayed because high winds prevented a safe lift-off.

Explanation for Incorrect Answer B:

Choice (B) is incorrect. "Forfeit" means to give up or surrender something. If one were to insert this term into the text, the sentence would read "Dangerously high winds forfeited attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The astronauts launching the space shuttle might "forfeit" their attempts because of high winds, but the winds cannot be said to have "forfeited," or given up, the attempts to launch the shuttle.

Explanation for Incorrect Answer C:

Choice (C) is incorrect. "Implement" means to accomplish or carry out. If one were to insert this term into the text, the sentence would read "Dangerously high winds implemented attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The high winds did nothing to help accomplish an on-time launch of the space shuttle. In fact, they prevented the launch from occurring on schedule.

Explanation for Incorrect Answer D:

Choice (D) is incorrect. "Discharge" means to release. If one were to insert this term into the text, the sentence would read "Dangerously high winds discharged attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The attempts to launch the space shuttle on schedule were in no way released by the high winds; in fact, the winds prevented these attempts.

Explanation for Incorrect Answer E:

Choice (E) is incorrect. "Redouble" means to strengthen. If one were to insert this term into the text, the sentence would read "Dangerously high winds redoubled attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The high winds clearly did not strengthen the attempts to launch the space shuttle on schedule, as the launch was actually delayed.
