Question

which excerpt from a lab report is more formal? this is an experiment where we looked at how the body needs lots of energy. this experiment focused on the energy requirements of the human body.

Explanation:

In academic writing, formal language is more precise and uses technical or standard terms. The first excerpt uses "we looked at" (a casual phrase) and "lots of" (a non - technical, informal quantifier). The second excerpt uses "focused on" (a more formal verb choice) and "energy requirements" (a more technical and precise term instead of "needs lots of energy").

Answer:

This experiment focused on the energy requirements of the human body.
