Clothes made from natural fibers such as cotton, unlike clothes made from artificial fibers such as polyester, often shrink when washed at high temperatures. The reason for this shrinkage is that natural fibers are tightly curled in their original state. Since the manufacture of cloth requires straight fibers, natural fibers are artificially straightened prior to being made into cloth. High temperatures cause all fibers in cloth to return to their original states.

Summary
Clothes made from natural fibers, unlike artificial fibers, often shrink when washed at high temperatures. Why? Because natural fibers are tightly curled in their original state. The manufacture of cloth requires straight fibers, so natural fibers are straightened before being made into cloth. High temperatures cause all fibers to return to their original states.

Strongly Supported Conclusions
In their original state, artificial fibers are straight.

A
Washing clothes made from natural fibers at low temperatures causes the fibers to straighten slightly.
This answer is unsupported. We don’t know from the stimulus what effect washing clothes at low temperatures causes. We only know that high temperatures cause natural fibers to shrink.
B
High temperatures have no effect on the straightness of fibers in clothes made from a blend of natural and artificial fibers.
This answer is unsupported. We don’t know from the stimulus what happens when clothes are made from a blend of fibers.
C
Clothes made from natural fibers stretch more easily than do clothes made from artificial fibers.
This answer is unsupported. We don’t know anything about stretching ability of either type of fiber from the stimulus.
D
If natural fibers that have been straightened and used for cloth are curled up again by high temperatures, they cannot be straightened again.
This answer is unsupported. We don’t know from the stimulus whether or not the process used to straighten the fibers originally could be used again once the fibers return to their original state.
E
Artificial fibers are straight in their original state.
This answer is strongly supported. We know from the stimulus that artificial fibers do not shrink when washed at high temperatures. We also know that high temperatures cause all fibers to return to their original state. Therefore, artificial fibers are originally straight.
