It seems you have gone to tremendous lengths to construct an analysis, and unfortunately, it's all a little off the mark. You see, often in a GMAT CR question, it's hard to make a simple "recipe" for what you can and can't ignore. Think about what we know and don't know by the end of the prompt. What we know:1) We know the environmental advocates want to save fish not targeted by commercial fishing. 2) Toward that end, they have come up with a new kind of net, that appears to be designed specifically for what the commercial fishermen want to catch. 3)The environmental advocates want a solution that saves the fish but doesn't interrupt the business of fishing. What we don't know: 1) Do these nets really work as they are intended? 2) Do we know that these new nets are going to get used?Those are concerns that the prompt leaves open. Anything that strengthens one of these would be helpful? The problem with (C) is not the topic itself, but that it works in the wrong direction. If the new nets were significantly cheaper than the previous nets, we would have no doubt that the fishermen would use them. This would be a strengthener, though not the strongest strengthener. Instead, (C) goes in the opposite direction: the new nets are slightly more expensive than the old nets: that's no a huge impediment, but by itself it doesn't suggest a run on the market. By itself, it doesn't suggest the widespread use of the nets. That's the most compelling reason to reject (C). Does all this make sense?Mike

The passage clearly specifies that the pheromones are for the commercially sought after fish, however the passage does not specify anything how the endangered marine species react to these pheromones.Dear nikhilkayath, I'm happy to respond. My friend, think about the prompt question:Which of the following, if true, most strongly supports the claim that use of the new nets will have the intended effects?This is a relatively standard prompt. In order to evaluate any answer choice, we have to assume that it is completely true, just as the evidence in the prompt argument is. Thus, when we consider (A) as a possible answer choice, as an essential part of that exercise we have to assume that (A) is completely true. Thus, we know how the "endangered marine species" would react, and this reaction significantly strengthens the argument. This question is a strengthen the argument question, and the prompt explicitly tells us that we have to assume that each answer choice is true. By contrast, in other CR questions types, such as an inference question, our job is to figure out whether each answer choice is true. On the different kinds of CR questions, are job is very different, and a student inevitably will get the question wrong if the student is trying to perform one task when another is demanded. It's very important to know and be clear on the different CR tasks. Does all this make sense?Mike

 Author: Gabrielantonioreis [ 30 Oct 2017, 02:37 ] Post subject: Re: Bottom trawling is a type of deep-sea fishing that involves dragging a For me "threat" in A is ambiguous and makes people think that the endangered species would ended up killed because of the use of pheromones on the net. I think that this answer choice should be rephrased.

If the pheromones in the nets simultaneous attract the fish sought by the commercial fishers, and repel the endangered marine species, that kills two birds with one stone! It's good for the commercial fishers, and it does what the environmentalists want: a win-win scenario! This is a very clear strengthener.Choice (B) talks about the large size of some of the endangered species. The nets are quite specifically designed for individual species, some of which are large or small. IF anything, a large endangered marine species would not be caught in any of the nets designed for much smaller animals. Even if it suggests the plan would work for these few large species, that doesn't indicate whether the plan would be successful overall. This is not a particularly compelling strengthener.Choice (C) is tempting --- if the new nets were really cheap, that would help the commercial fishers, which is one of the goals. We have to be careful here. Choice (C) begins "most of the newly designed nets …" Saying that most are not expensive strongly implies that some are, and this would be problematic for the commercial fishers. This does not support all the claims.Choice (D) indicates very broadly that protecting the endangered marine species could be compatible with the business interests of the commercial fishers, but this tell us zilch about whether this particular plan, involving the new nets, will work at all.Choice (E) presents an argument by analogy: freshwater fishers use different hooks to target individual species, much as this plan proposes using different nets. This suggests in a general way that this plan could work, but it doesn't make clear that the new plan involving the nets definitely will work.

 Author: Appler [ 22 Jan 2019, 06:23 ] Post subject: Re: Bottom trawling is a type of deep-sea fishing that involves dragging a Purpose of the plan is to protect the endangered species without interrupting commercial deep-sea fishing.(A) The pheromones that would most attract the food species sought by commercial fishers indicate the presence of a dangerous threat to most of the endangered marine species.Once the endangered species are aware of the presence of the threat, they won’t be endangered any more.(B) Some endangered marine species are particularly large, as large any species targeted by commercial deep-sea fishing. We are not comparing the size of the fish. Size is not our concern.(C) Most of the newly design nets are not significantly more expensive than a typical bottom trawling system. Cost is not our concern.(D) Catching unintended, endangered species adds nothing to the profits of a commercial deep-sea fishing company.Profit is not our concern.(E) Freshwater fishers often increase the odds of catching a desired fish, and avoid catching unintended species, by the specific design of the fishing hook. Does it protect the species we would like to save? Unanswered!

 Author: NinetyFour [ 22 Jan 2019, 23:27 ] Post subject: Re: Bottom trawling is a type of deep-sea fishing that involves dragging a Hi, I chose D over A because A the wording is too soft. It says most of the animals instead of ALL of the animals. Since it is most of the animals, then that means some endangered animals will still be affected.In D however, we get a more definitive reason to say the plan will work. D helps us limit a potential reason fishermen might have to catch the endangered fish. What if the fish adds to their profit? Then the fishermen will not use the new nets.

Note here that nothing is mentioned in the argument about how the endangered species would identify that there is a threat when they go near the nets. If you add the information in Option A, we can support this claim by saying that the pheromones would deter the endangered species from going near the new nets, meaning that the pheromones that the author is suggesting to use actually attract the food species as well as repel the endangered speciesarchanam9449 wrote:For all we know pheromones could have been part of the previously used nets as well.They may or may not have been used with the previous nets. Even if they were used, since the author is suggesting to use pheromones which specifically attract the food species these commercial fishers are interested in, we can safely assume that NOT ALL or FEW were using such specific pheromones previously.Sudheer
