问题 According to a growing number of experts, it is already technically ______ to construct a pioneering space colony, powered by solar energy.
选项 A、practical
B、flexible
C、feasible
D、beneficial
答案C
解析 本题中，C项feasible“可行的，切实可行的”符合题意，如：His story sounds feasible．他讲的似乎有理。其他三项practical“实际的，实践的”；flexible“柔韧性，易曲的，灵活的”： beneficial“有益的，受益的”都不正确。
