That its a very good book because so many want to read it.
Guesses is the plural form
Get into your closet and hide in the farthest corner but take your phone. Then text your parents (turn your sound off and even your vibrate) if they are there if they aren't go out a window and go to your neighbor's house. but if you don't quietly open your door and bolt to a room that does or if you can the front door don't trip and keep a cool head also investigating isn't a good choice and just hope that it was only something falling down.
Hard choosing from "A" to "D", but my best answer that I came up with is "D" or "4"
The word "Who's" is a plural and actual stands for "Who is" So if you put that in that sentence "Who is book about blue whales is this?" Or for "2" the word "Whomever's" doesn't make since in the sentence.. "Whomever's book about blue whales is this?" And the same with "3". But with "4" "Whose" It fits in that sentence.. "Whose book about blue whales is this?" It's best if you read the sentence out loud and see which word best fits in that sentence.
