Special kinds of cotton that grow fibers of green or brown have been around since the 1930s but only recently became commercially feasible when a long-fibered variety that can be spun by machine was finally bred. Since the cotton need not be dyed, processing plants avoid the expense of dyeing and the ecological hazards of getting rid of leftover dye and by-products.

Summary
Special cotton from green/brown fibers havae been around since 1930s. Only recently, this special cotton became commercially feasible when a long-fibered kind that can be spun by machine came about. This long-fibered kind doesn’t need to be dyed, which is why processing plants don’t need to spend money on dyeing. In addition, since the long-fibered variety doesn’t need to use dyes, plants don’t need to get rid of leftover dye from processing, which avoids some ecological damage.

Very Strongly Supported Conclusions
There’s no obvious conclusion to draw from these facts. I’d go into the answers thinking, “There are at least some advantages to the long-fibered variety of cotton from green/brown fibers over the non-long-fibered variety of that cotton.” But the correct answer could be unexpected.

A
It is ecologically safer to process long-fibered cotton than short-fibered cotton.
We know that the long-fibered green/brown cotton doesn’t have a certain ecological risk (because it doesn’t require dyes). But this doesn’t extend to long-fibered cotton that isn’t green/brown. We don’t know about ecological risks of other kinds of long cotton.
B
Green and brown cottons that can be spun only by hand are not commercially viable.
Strongly supported, because the green/brown cotton “only recently” became commercially feasible, and this happened after a variety that could be machine-spun “finally” came about. This suggests that before a machine-spun version came about, it wasn’t commercially viable.
C
Hand-spun cotton is more ecologically safe than machine-spun cotton.
We don’t get a comparison concerning ecological damage between machine-spun vs. hand-spun cotton. All we know about ecological risk is that if you don’t have to use dyes, you avoid at least one ecological risk.
D
Short-fibered regular cottons are economically competitive with synthetic fabrics.
We don’t get any comparison between short-fibered cottons and synthetic fabrics.
E
Garments made of green and brown cottons are less expensive than garments made of regular cotton.
We know that processing plants don’t need to spend on dyes for creating green/brown cotton. This doesn’t suggest that clothes from green/brown cotton are less expensive, however. There are many other costs that go into clothing; we can’t go from the lack of one specific cost with respect to the cotton to a claim about overall cost of clothing from the green/brown cotton compared to other clothing.
