questions -- a book from "Mary had a little jam and other silly rhymes

 I read this book little by little.

Q1

Mary, Mary, quite contrary

 what does your garden grow?

Spinich? Broccoli? Cauliflower?

 To which Mary ansserd, "No!"

What is the silly part?

Does the questioner ask her the least favorite vegetables?

Q2

Peter, Peter, sugar eater,

always wanted food much sweeter.

Adding sugar was a blonder.

Now he is a toothles wonder.

Why the boy Peter is a toothles wonder?

He ate sweets too much, so his all teeth were gone by cavity?

Or luckily all his baby teeth have gone naturally without cavity to chane into adult teeth?
