Read the excerpt from The Building of Manhattan. In 1930, these workmen either went bare­headed, wore a cloth cap—often worn backward—or wore a battered felt hat. The rigid plastics needed for molded head protection, called "hard hats," would not appear until after World War Il.

Which choice is the best paraphrase of the text?

The types of stiff plastic needed in the manufacturing of “hard hats,” or hats that protect the heads of construction workers, were not available until after World War ll. For this reason, construction workers in 1930 either did not wear hats or wore cloth caps, often backward, or shabby felt hats.
Plastics to make hard hats were not available in the 1930s, so workers either did not wear hats or wore hats made from cloth or felt.
I would not have wanted to be a construction worker in 1930, because they were not given protective headwear. The kinds of plastics needed to make “hard hats” had not been invented yet, so construction work was more dangerous.
