Self-study
Clothes made from natural fibers such as cotton, unlike clothes made from artificial fibers such as polyester, often shrink when washed at high temperatures. ███ ██████ ███ ████ █████████ ██ ████ ███████ ██████ ███ ███████ ██████ ██ █████ ████████ ██████ █████ ███ ███████████ ██ █████ ████████ ████████ ███████ ███████ ██████ ███ ████████████ ████████████ █████ ██ █████ ████ ████ ██████ ████ ████████████ █████ ███ ██████ ██ █████ ██ ██████ ██ █████ ████████ ███████
Summary
Clothes made from natural fibers often shrink when washed at high temperatures. This does not happen with clothes made from artificial fibers. Shrinkage occurs because natural fibers are tightly curled in their original state, but must be straightened before being made into cloth. High temperatures cause all fibers to return to their original states.
Strongly Supported Conclusions
The stimulus supports the conclusion that if straightened fibers that were used to make clothing return to being tightly curled, that causes the clothing to shrink. It also supports the conclusion that artificial fibers are straight in their original state.
