I think E is right. B doesn't even really make sense. The optimization algorithm is supposed to be used to find out the optimal number of species that can be protected within a hotspot.. It is not a conservation technique to be used in combination with other techniques, nor is it correct to assume that this algorithm would be useful in applying other techniques more efficiently.. Weird if B is the OA

Hi I also thought that it was E, but it is not as E is mentioned in the argument, thus, it is not an inference.

B is an inference as it shows both methods are combined, the argument mentions Method 1 AND Method 2 are used

B it is,

It is an inference question.
As per the argument,
Researchers say that we should use optimization algorithms and conservation methods, so that no aspect of preservation is ignored.

Option B says the exact same thing. So B it is.

It is B straight.

The stimulus initially mentions that biodiversity method is not effective. E twists this and says biodiversity method has better potential which is not true. Potential of biodiversity method is not in question here. Therefore we cannot infer E.

The stimulus provides two steps to improve conservation of species:
1. Use Optimization algorithm to find maximum number of species that can be protected.
2. Use more methods of conservation than are currently being used.

B states exactly the same, use Optimization algorithm along with other conservation techniques.

Hope it helps!

Its B.

We don't have enough information which can help and support option E.

Hello from the GMAT Club VerbalBot!

Thanks to another GMAT Club member, I have just discovered this valuable topic, yet it had no discussion for over a year. I am now bumping it up - doing my job. I think you may find it valuable (esp those replies with Kudos).

Hmm I must say i chose E first.

But when you stop and think about the logical structure as suggested by egmat , i think we can crack this:
1. Biodiversity hot spots ---> NOT most effective method to protect species
Why? ---> Because the overlap of species is small (No problem if you can't understand this)
2. Researchers suggest:
---> Use of optimization algorithm to determine HOW MANY Species can be protected.
---> And also use more and varied conservative techniques

Now analyse E: It says Biodiversity hotspots are not saving as many species as they can. The researchers are not talking about HOW MANY species biodiversity hotspots can save, they are more worried about how well the endangered species can be protected. And that means Optimization algorithm may show that at a hotspot or some environment maybe two species can thrive well and be saved instead of 5 species clogged in together (hypothetical case, just for understanding I am saying ) So basically its not quantity but quality on which the researchers want to focus. E doesn't do that.
Now A, C and D can be ingnored:
A ---> nothing in passage suggests how many techniques environmentalists use
C ---> nowhere is it said the optimization is the most effective!
D ---> No suggestion of whether biodiversity hotspots will benefit

So you're left with B.

Sometimes you don't need to see the answer, you need to know whats wrong to reach the right I learnt it the hard way, will try to incorporate this thought process in all CR questions

Request you not to write your queries/answers/opinions in question window. It prevents ppl from analysing the question. The whole purpose of GMAT Club forum goes wasted by doing so.

You have response windows to do all such things.
