A. Did you understand everything today?
B. No. I’m so confused.
A. So am I.
B. She doesn’t explain things very well. She goes too fast!
A. I know. And now we’re going to have a test!
You can infer that these two people are in a classroom because of the following evidence:
Is it B?
A. Person "B" said someone "moves too fast".
B. Person "A" said they were going to have a test.
I think that the correct answer is: A. because tests are given at school in a classroom to see what you learned before that. Hope that helps. Sorry if the answer is incorrect.
