📖 題組：
On average Americans chew about 300 sticks of gum per person a year. Why is chewing gum so popular? Some people say that it not only helps you relax but also helps you stay awake. Others chew gum after a meal to have fresh breath. It can help fight tooth decay as well. But few people know that there is an even better reason for chewing gum—it can improve memory! In an experiment, the scientists divided 75 people into three groups. One third chewed real gum, one third chewed imaginary gum, and the last third didn’t chew anything. Then, each group was given a lot of different memory tests. The results were very interesting. The people with real gum did better than those with imaginary gum, and the latter did better than those who didn’t have any gum at all. How does chewing gum help memory? One possible reason is that when people chew, there is more activity in an area of the brain that is important for memory. Another possible reason is that when people chew, their heart beats faster so more oxygen goes to the brain. So, do you have an exam coming up? Start chewing now!

請試著觀察文章的結構：作者在第一段的中間使用了一個轉折詞 'But'，在那之後，文章花了最大的篇幅在描述哪一個具體的科學實驗？這個實驗最終證實了口香糖對人體哪一項功能最有幫助呢？

掌握主旨：從背景到核心發現
太棒了！你能精準地從文章層層遞進的敘述中，抓出作者真正想強調的核心訊息，這顯示你具備相當敏銳的閱讀觀察力。文章雖然開頭先提到了口香糖的普及性以及提神、保持口氣清新等大眾熟知的好處，但真正的轉折點在於 "But few people know..." 這句話。你正確地捕捉到後續篇幅多數都在描述實驗過程、結果以及生理上的原因分析，這些內容全都緊扣著「口香糖與記憶力」的關聯，因此選擇 (C) 作為標題是最完美的。
