Henry was not   at math. Even when the teacher explained something a second time, he still couldn’t     it.
“Never mind. I’ll sit    the boy who’s the best at    ,” Henry thought, “and      his answers.”
The day of the exam    , and Henry sat next to Allan,     was    at the top of the class in math. Henry copied Allan’s answers     his own exam paper. At the end of the exam, the teacher said, “Well, boys and girls, I’ve decided to give a red    to the student who got the    grade. It’s     for me to decide who I’ll give the star to, however,       two students, Henry and Allan, got the     grade.” After a moment she went on, “       I’ve decided to give the star to    this time.”
Henry was _  __ when he heard this. He stood    and said, “But I got the same grade as Allan, madam.”
“That’s    .” The teacher said. “However, Allan’s answer to Question 6 was ‘I don’t know.’, but    was ‘Nor do I.’ .”
