   No Impact2% picked this

   The cost of organic solvents is only one of many expenses involved in industrial

   This just tells us that there are lots of expenses chemical companies consider. It doesn't give us any way to say that it would be worth it to use the more expensive ionic liquids.

   New methods for removing by-products of chemical reactions have recently

   One of the benefits we were hoping to get from ionic liquids was fewer by-products, but this answer is actually helping the 2nd person argue, "Relax -- we can use the cheaper organic solvents, since we've got new ways to get rid of the by-products."

   Doesn't Address Objection1% picked this

   The chemical industry has historically been quick to adopt new techniques that increase the rate

   Ionic liquids do speed up reactions, so this answer would kinda make it sound like ionic liquids are the type of thing the chemical industry has historically been quick to adopt. Although that somewhat fits our goal of arguing for ionic liquids, it doesn't respond at all to the objection that they are way more expensive than organic solvents.

   Ionic liquids can be reused many times, whereas organic solvents can be

   Why this is right

   This gives us a way to defend the higher upfront cost of ionic liquids -- they last much longer than organic solvents. If you can use ionic liquids 5 times and organic solvents only once, then ionic liquids could be 5 times as expensive and still provide the same value.

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

   No Impact (slightly more expensive)3% picked this

   For the sake of public relations, companies will sometimes use a more environmentally friendly process even if it

   Ionic liquids are more environmentally friendly since they lead to less air pollution, so this answer somewhat sounds like it argues in favor of ionic liquids. But they are MANY times more expensive than organic solvents, not just slightly more expensive, so this doesn't really apply to ionic liquids.
