the correct sentence here is definitely (c).
also note that this is actually an OG supplement problem (it's #65 in the OG verbal supplement).
however, this thread dates from before the ban on that source (the thread was posted in july 2007; the ban didn't go into effect until october 2007), so we'll leave it up.
However, after analyzing further I realised that the answer is E.
no.
The correct sentence would be (choice E):
The market for recycled commodities, like the commodities of aluminum and other metals, remains strong despite economic changes in the recycling industry.
there are two gigantically huge problems in this answer choice.
1/
this sentence mistakenly says that
the market for recycled stuff is "like the commodities of xxxxxx".
that's nonsense; a market is not "like" a bunch of commodities.
2/
the aluminum and other metals
are the commodities, so "the commodities of aluminum and other metals" is nonsense.
as an analogy, "the color of my skin" makes sense; "the color of my skin tone" is nonsense (because "skin tone" already refers to a color).
Aluminum and other metals cannot be recycled commodities.
hm? sure they can. aluminum is recycled all the time.
