Grandpa Joe is sharing his wise life advice with his grandchildren. He loves making broad, general statements about the world. Select ALL the sentences where he correctly talks about things in general.
The correct answers are Dogs are great friends. and Books are fun to read.
We use the zero article (no article) when making general statements with plural countable nouns (dogs, books) and uncountable nouns (sugar, money). Saying "the sugar" or "the money" is incorrect here because Grandpa Joe is talking about all sugar and all money, not a specific pile of it!
