   No Impact12% picked this

   Even if the quantity of nitrous oxide released into the environment decreased, many environmental problems

   This is saying that even if we stopped using nylon and thus decreased the emission of nitrous oxide, there would still be environmental problems. Yes of course. We didn't think this would solve every environmental problem. The author is only saying we'll be better-off, not that we'll be 100% fixed. This choice might suggest a limitation of the switch, but it does not weaken the argument about the relative benefit of reducing nitrous oxide.

2. B

   Opposite Impact2% picked this

   Even if only some of the thread and rope that is currently being made from nylon were instead made from cotton fiber,

   Choice (B) suggests that switching only some products from nylon to cotton reduces environmental damage, which actually supports the idea that using cotton fiber is less damaging environmentally. This does not weaken the argument; rather, it strengthens it.

   If cotton fiber replaced nylon in the production of thread and rope, there would be a resulting increase in the amount of

   Why this is right

   This suggests that the intended reduction in nitrous oxide emissions might not occur or would be offset by increased nylon use elsewhere, thus negating the environmental benefit the argument claims. This choice effectively weakens the idea that switching to cotton fiber for thread and rope would lead overall to less environmental damage. There would be less damage coming from thread and rope production, but a commensurate increase of nylon use in other products, so we'd still get the environmental damage from nylon.

   Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

   Strengthens2% picked this

   If the quantity of nylon manufactured annually decreased substantially, the volume of several pollutants that are released into the environment during

   This seems to say that if switch to cotton and use less nylon, we'll also get less of several pollutants that often come with producing nylon. That sounds better for the environment, so it strengthens.

5. E

   Irrelevant Comparison2% picked this

   If thread and rope continue to be made from nylon, the production of cotton fiber will not increase as rapidly as it would if

   Choice (E) deals with the production rate of cotton fiber and its impact, not the environmental consequences of using cotton versus nylon. The change in production speed does not inherently affect the environmental damage aspect and thus it does not weaken the comparison made regarding environmental damage.
