Question

give up a sample, the technologist recalls, adding that contents of the ragtag bale looked even less promising when it was opened. cotton at this stage is a mass of tangled fibers of varied lengths. it contains dirt, sand, particles of leaf and stalk of the cotton plant, and some seed fragments.
④ after opening, cotton from many bales was blended, then vigorously cleaned in several operations, damaging the fibers as little as possible. the matted clumps of cotton, sometimes hard as wood, were then reduced to small tufts and eventually to separate fibers on their way to spinning into yarn.
⑤ over the years, the southern laboratory has made uncounted improvements in every step of cotton processing. these include better machinery; smoother, more efficient processes; and innovative testing equipment. these developments helped save the u.s. cotton industry.
how does the author connect the details about cotton processing in paragraphs 1 and 5?
by revealing the need for regional leadership in improving american industries.
by conveying how the once - stagnant cotton industry improved its processes after world war ii
by demonstrating the need for skilled workers at every stage of cotton processing.
by proving how assembly line offer the most efficient method of textile production.

Explanation:

Paragraph 1 describes the initial state of cotton (mass of tangled fibers etc.). Paragraph 5 talks about improvements in cotton processing (better machinery, more efficient processes etc.). The connection is that it shows how the once - stagnant cotton industry (as described in its initial state in paragraph 1) improved its processes (as detailed in paragraph 5).

Answer:

By conveying how the once - stagnant cotton industry improved its processes after World War II.
