On the flight leaving New York, The stewardess was kind.
Hello!
1. The first blank would be plural. For example:
dogs & cats
tables & chairs
2. The second blank would be singular. For example:
He (singular) runs
She (singular) plays
vs.
They (plural) run
They (plural) play
I hope this helps!

Because expository writing is writing about why things are the way they are, thus what caused them.<span />
