Question

some millworkers operated spinning machines. these machines took loosely wound strips of cotton, pulled them tight, and twisted them to form yarn. this yarn was then wound around spools. when the spools were full, workers called bobbin girls or doffers removed the full spools and replaced them with empty ones.
this picture shows a doffer at a spinning machine. look at the picture. then follow the instructions below.
loose strips of cotton
finished spools of yarn
use the information above to complete the text.
master the task quickly
lift heavy bales of cotton
reach the spools easily
go to school

Explanation:

The task is to select the option that fits the role of a doffer/bobbin girl, who removes and replaces full/empty spools on a spinning machine. The doffer in the image is positioned to access the spools, so the relevant skill is being able to reach them easily. The other options are unrelated: lifting heavy bales is not their task, mastering quickly is not specific to the action shown, and going to school is irrelevant to the work.

Answer:

reach the spools easily
