How does an inline UPS protect computer equipment against electrical power brownouts and blackouts?

omg taking this same test i was stuck on the same question i was too lazy to read the book sadly i cant really give you an answer to this question too complex the answer will be in chapter 5 of the cay

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.

hope this ! : 3

that would be my answer.
