Questions 1-3 are about the following letter from a teacher.

Dear Class,

I am writing to tell you about the African safari that I'm on. I promised I'd send you an update as soon as I had the time. You should know that I was touched by how interested you were in my trip. After spending some time here, I think you should come on a safari if you have the chance. There are many volunteer projects in Africa that need helpers. I encourage you to get involved.

I know you were most interested in African animals. On the safari, I've been able to see lions, giraffes, zebras, gazelles, as well as many other animals. My favorite was the giraffes. Did you know that they have blue-black tongues? I didn't! They're incredibly long - about eighteen inches! Giraffes use these long tongues to eat leaves from acacia trees with sharp thorns. As for the lions, it was incredible to see them in the wild. The male's mane was quite impressive.

Anyway, I hope you're behaving yourself for your substitute teacher, Mr. Wilson. The school was kind enough to give me these two weeks off to participate in this project. So I hope you are showing that you can behave and study hard without me. I'll be back to school on Mortday the 11th, so I've sent this letter express mail. I hope it reaches you before I get back. When I return, I'll show you all of the photos that I've taken. I'll see you soon.

Mrs. Lee
