B, C, and D are all mentioned in the passage, but the text as a whole is about how important water level is in the car battery.

In the first sentence, both "checkers" and "game" are nouns, right? Person, place, or thing. You can also test for most nouns by putting a "the" in front of it. (Usually not proper nouns.)
