问题 It will be emphasized that commercial space operations are inherently complex, long-term, capital-hungry, and set by a variety of risks.

选项 A、beset by
B、inset by
C、preset by
D、reset by

答案A

解析 动词搭配beset(后面常与by连用)困扰;inset插页,插入,嵌入(一般不与by连用);preset预先安置,预先调试,事先调整;reset重新安排;后面三个词大多作及物动词;而本句意为:需要强调的是民用太空计划复杂,耗时长,资金缺且风险重重。因此A为答案。
