Answer:
I believe the pair of lines that expresses a humorous tone is:
<u>"But, now that I'm perfectly sure I have none, </u>
<u>Why I do it again and again."
</u>
Explanation:
The pair of lines above is dictating the humorous tone of the poem "You are Old, Father William". It ends the interaction between father William and his son in a comical, surprising way. The father is obviously older than his son, which leads us to expect him to be wiser. Still, he claims to have no brain. Perhaps he means he has lost his mind, which would explain why he stands on his head at such an age. It's as if he is aging backwards - his body growing older, but his mind getting younger.
Paragraph 1.
"Oh!," said Goldilocks, "the controlling idea is too vague. As a reader, I can't tell what your essay will really be about. When writing a controlling idea you want to be specific."
Paragraph 2.
"Oh my," exclaimed Goldilocks. "This controlling idea is too wordy. A controlling idea should be clear and concise. That was I will know what your essay is about."
Paragraph 3.
"Well, well," Goldilocks said. "this controlling idea doesn't address the prompt. When you look at what it is asking you to write, don't you see how it is asking you to explain the importance? This just says it is is important. But I do like how you thought of another word that means to not give up!"
