参考答案及解析：
1.The correct answer is B
Explanation
Choice (B) is correct. It is logical that the owner of a five-year-old computer would be concerned that her machine would soon be “obsolete,” or no longer useful, given the recent changes in computing.
2.The correct answer is B
Explanation
The archaeologist “never stayed at any one site long enough to get bored.” Her life can be described as “nomadic” or characterized by moving from place to place.
3.The correct answer is C
Explanation
It is logically consistent to say that someone who is “dynamic,” or energetic, would feel restless, or agitated, when faced with a boring task.
4.The correct answer is A
Explanation
Choice (A) is correct. We know that “striking and unexpected” describes both the actor’s rise and his decline; “sudden” fits with this description, as does “meteoric,” which means suddenly or temporarily brilliant.
