One day in class, the teacher held up an apple. She stood on the platform (讲台) and said, "Please 1 it in the air, and…"
One student 2 his hand and said, "I can smell it. It is the smell of an apple."
The teacher stepped 3 the platform, passed by each of the students and said, "Smell 4 to see if the smell of the apple is still in the air."
Half of the students put up their hands to show that they could smell it. The teacher returned to the 5 of the classroom and asked again who else could smell the apple. The rest raised their hands except one boy. The teacher came to the boy and asked, "You really can't smell the apple?"
The boy answered, "No, I can't smell it. I don't think it's a 6 apple."
The teacher 7 at the boy and said to the class, "He's right! It's not 8 to get the apple smell from this apple."
All of the other students had been tricked. Some may have thought that perhaps the apple didn't have the apple smell, 9 they didn't dare to speak up. They just 10 the first student blindly and went along with him.
