frozen food
clarence birdseye returned to the united states from canada and designed
a quick-freezing machine. before the 1930s, some people did not want to
buy frozen foods because they thought that freezing food reduced the quality.
birdseyes machine improved the flavor and texture of frozen foods. soon,
people wanted these improved frozen foods, and stores all over the united
states began to offer foods that had not always been available before.

which statement tells how clarence birdseye changed frozen food?
he reduced the availability.
he increased the quality.
he slowed the freezing process.
he designed a machine in canada.

Explanation:

The text states that before Birdseye's machine, people avoided frozen foods thinking freezing reduced quality, and his machine improved the flavor and texture (i.e., quality) of frozen foods, leading to wider availability. The other options are incorrect: he increased availability, not reduced it; his machine was a quick-freezing one (not slowing the process); he designed the machine after returning to the US, not in Canada.

Answer:

He increased the quality.
