Carlos is revising his essay about long-distance bird migration. he wants to add more details. what detail would be most effective?
many types of birds can fly a really long way on air currents.
sometimes in fall you may see geese migrating south.
one species of bird called the manx shearwater migrates 8,700 miles.
everyone loves seeing birds migrate in the spring and fall.

the correct answer is a "it describes nora and mrs. linde's relationship". opcions b and d are not related to the content of the passage in any way. option c could be appropiate but it does not fully capture the effect of the dialogue, while option a is quite appropiate, since the dialogue not only exemplifies the relationship between the characters, but it also captures the effect in the excerpt. we get to know that mrs linde bosses around and already knows nora.
