Answer:
Your answer would be the following: for/among. That is, the first sentence would be as follows: after his cousins arrived, brianna waited for them with food. The second would be as follows: The beads were distributed among the 5,000 fans of "squeaky" johnson.
Explanation:
The first choice is the preposition for because it is a fixed collocation. The verb to wait always goes with the preposition for. Then, in the second sentence, the right choice is among. The more accurate difference between among and between is that between is used when naming distinct individual items and among when the items are part of a group or not specifically named. Between is also used to refer to 2 or 3 items, whereas among is used to talk about 3 or more. That is why among is the right choice here.
