📖 題組：
Sometimes when the rain falls hard and fast on you, it might hurt a little. But what happens when it hits a mosquito? A 2012 study says when a raindrop falls on a mosquito, it’s like when a bus hits a person. Besides, the little insect is hit by a raindrop about once every 20 seconds. So why don’t we see many dead mosquitoes after it rains? A mosquito is as big as a raindrop, but it is much lighter—0.002 g only. This saves its life in raindrop attacks. Because the mosquito is so light, when it is hit by a raindrop, it won’t experience a force that is strong enough to kill it. The study also found that when a mosquito is hit by a raindrop, the insect is pushed by the raindrop and falls together with it. But the mosquito doesn’t get wet easily because it is covered with hairs which keep off water. After dropping about 6 cm, it will roll off the raindrop and fly away. However, this trick isn’t always successful. If the mosquito flies too low when it is hit by the raindrop, it won’t have time to fly off. Then it will hit the ground and meet its death.

請在文章最後一段找到 'this trick' 這個詞，它通常指的是前一段所描述的行為。請回頭看第三段：當蚊子被雨滴撞擊時，牠會先跟著雨滴做出什麼動作？最後在大約掉落 $6$ cm 後，又是如何脫離雨滴並飛走的呢？

哎喲，竟然寫對了？我還以為你會選 (D)，幻想蚊子在那邊衝浪咧！看來你今天出門前有記得把大腦帶上，真是謝天謝地，沒讓我在這題就氣到血壓飆高。 觀念驗證： 這題考的是「細節定位」。文章第三段白紙黑字寫著：當蚊子被撞到時，「is pushed by the raindrop and falls together with it」（被雨滴推著一起下墜），然後「roll off the raindrop and fly away」（從雨滴上滾開並飛走）。這就是蚊子在雨中生存的「trick」（把戲）。它利用自己只有 $0.002 \text{ g}$ 的極輕體重，玩了一齣「順勢而為」，才沒被雨滴這台「公車」撞死。
