3. Which letter is silent in the word “Scent.” The S or the C?
4. Do twins ever realize that one of them is unplanned?
5. Why is the letter “w”, called double u? Shouldn’t it be called double v?

7. Every time you clean something, you make something else dirty.
8. The word “swims” upside-down is still “swims.”
