Final answer:
To convert cups to pints, divide the number of cups by 4 to get the number of quarts. Since 1 quart is equal to 2 pints, the server poured 1 pint.
Step-by-step explanation:
To convert cups to pints, we need to use the conversion factor that there are 2 pints in 1 quart. Since 1 quart is equal to 4 cups, we can divide the number of cups by 4 to get the number of quarts. In this case, the server poured 4 cups, so we divide 4 by 4 to get 1 quart. And since there are 2 pints in 1 quart, the server poured 1 pint. Therefore, the correct answer is C) 1 pint.
