问题 According to the passage, destruction caused by high waves occurs ______.
We know from this passage that out at sea, when waves going in opposite directions meet, their force ______.

选项 A、cause great damage
B、extends to the ocean floor
C、is liable to lessen
D、increase rapidly

答案C

解析 本题为细节题。题干是“由文章可知当两股方向相对的海浪相遇时,它们的力量……”由文章第一段第三句“The two sets of waves tend to cancel each other out.”可知两股海浪力量相互抵消,与C项(力量减弱)相一致。
