Daniel is mapping out important family
events. He uses negative numbers to
represent time before he got his first cat, and
positive numbers to represent time after he
got his first cat. For example, Daniel's mom
was born in year -28, and Daniel got his
first dog in year 7. What does year 0
represent?
A. The year Daniel got his first cat
B. The year Daniel got his first dog
C. The year Daniel lost his first tooth
D. The year Daniel's mom was born
