B. What was Thomas's problem?

Решение:

В начале текста указано: "He had no idea what to write. He could not think of a good idea. He was thinking and thinking but his head was absolutely empty." Это говорит о том, что у Томаса совсем не было идей.

1. He had too many ideas and couldn't choose which to use.
2. He had no ideas at all.
3. He couldn't write, his right hand ached.
