Let's solve each question step by step:

Question 1:

Paragraph:
"There are many fun things to do at the beach. Swimming is one thing that can be done at the beach. Snorkeling is another thing that can be enjoyed. Playing beach volleyball can be a lot of fun. It is also fun to look for shells. Some people simply like to sunbathe."

The rest of the paragraph provides details about the kitten's characteristics (soft and cuddly, likes to sleep) and how Mary cares for it (providing a blanket, playing with it, feeding it).
