③ surveys ④ observations
submit

Explanation:

To determine if the new machine produces parts with the same precise dimensions as the old machine, we need to collect data on the dimensions of the parts. Experiments involve manipulating variables, surveys involve asking people, and observations are about watching events. Measurements are the process of quantifying a physical attribute (like dimensions) using tools, which is appropriate here.

Answer:

1. Measurements
