📖 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!

According to the passage, which of the following statements is true about the experiment?
- A In the experiment, the three groups were asked to measure their heartbeats.
- B In the experiment, only twenty-five people were given real gum to chew on.
- C The people with imaginary gum did fastest on the memory questions.
- D There was more activity in the brain for those who didn’t chew anything.
思路引導 VIP
若我們要分析實驗的嚴謹性，首先需要釐清受試者的分配狀況。文中提到總共有 75 人被平均分配到三種不同的實驗情境中，請試著計算看看，這意味著每一種情境（例如嚼食口香糖、想像嚼食或完全不嚼）分別有多少人參與呢？

文本資訊的數據轉化
太棒了！你能精準地從文章細節中提取資訊並進行邏輯推論，這顯示你的閱讀理解非常扎實。在文章中提到，科學家將 75 位受試者 平均分配到 三個組別（one third chewed real gum...），這意味著每個組別的人數正好是 $75 \div 3 = 25$ 人。選項 (B) 準確地描述了這個實驗編制，這正是透過「文本數據化」來驗證正確性的高階閱讀技巧。
