When claudius asks hamlet for he name of the play they were watching. hamlet says, "the mousetrap." what "mouse" does hamlet plan to "trap"?

I'll say maybe the third one:

McKenna overheard her mother say on the phone, “We’ll see you in fifteen minutes, Mom.” Fifteen minutes later, the doorbell rang. McKenna thought to herself, “My grandmother is here.”

Explanation:

She analized what her mom said through the phone and though "Well mi mom said that her mom was coming in 15 minutes so when the doorbell rang after 15 min she concluded that it was her grandma.

Hope this Helps God Bless You :)
