Questions 1-4 refer to the following e-mail.

Dear Ms. Kushner,

I'm writing to ask you about Friday's field trip to the aquarium. I never imagined (1)...about a field trip, but I'm really interested in sea animals. I have a question about (2)... us what we're supposed to bring for the picnic lunch afterwards. You said we're supposed to bring food, but I'm wondering if we're supposed to food to share with everyone or food for ourselves. I'm sorry for (3)... in class, but I didn't think of it until now. I hope you don't mind (4)...!

Sincerely,

Lindsay
