Question

units of measure
choose the best unit of measure by writing inch, foot, yard, ounce, pound, ton, cup, quart, or gallon.

1. serving of trail mix
2. height of a person
3. weight of a newborn kitten
4. gasoline

Explanation:

16. serving of trail mix

A serving of trail mix is a small quantity of dry food, and "ounce" is a suitable unit for measuring small amounts of such food (compared to pound which is larger, and volume units like cup/quart/gallon don't fit dry weight here).

For a person's height, "foot" (or sometimes inches in combination, but foot is a primary unit for human height) is appropriate. Inches are too small for a single unit (e.g., a person is not 60 inches tall usually expressed as 5 feet), yard is too large (3 feet), so foot is best.

A newborn kitten is very light. "Ounce" is a small weight unit, while pound is too heavy (a newborn kitten is often a few ounces, not pounds yet), and ton is extremely large. So ounce fits.

Answer:

ounce
