Answer:
1.) D.
Backstage, Keisha’s twin brother Colin chuckled quietly to himself. Above the curtain he had perched a large bucket of water—perfect for dousing his sister and the stage.
2.) B.
“she tapped her left foot nervously”; “little did she know that”
Step-by-step explanation:
1.) Dramatic irony is when the audience knows something the characters don't. Since Keisha doesn't know about her brother's mischief but readers do, this would be an example of dramatic irony.
2.) This is another form of dramatic irony because readers know that Keisha's friends are playing a trick on her she doesn't. Therefore, the second answer choice is correct because it shows the difference in Keisha's knowledge versus ours (as readers.)
