Q7. This is an unusual paragraph. I'm curious how quickly you can find out what is so unusual about it? It looks so plain you would think nothing was wrong with it! In fact, nothing is wrong with it! It is unusual though. Study it, and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out! Try to do so without any coaching!

答え：'e'が使われていないこと（'e'は英語で最も多く使われる文字です）。
こういうのって英語圏の人だとすぐに気付くものなんだろうか。
余談だがQ10の計算は何か意味があるのだろうか？順番に暗算していっても間違えそうにないけど…。これも英語圏と関係あるのかしらん。
