“Hot spot” is a term that ecologists use to describe those habitats with the greatest concentrations of species found only in one place—so-called “endemic” species. Many of these hot spots are vulnerable to habitat loss due to commercial development. Furthermore, loss of endemic species accounts for most modern-day extinctions. Thus, given that only a limited number of environmental battles can be waged, it would be reasonable for organizations dedicated to preserving species to _______.

Which one of the following most logically completes the argument?
(A) try to help only those species who are threatened with extinction because of habitat loss
(B) concentrate their resources on protecting hot spot habitats
(C) treat all endemic species as equally valuable and equally in need of preservation
(D) accept that most endemic species will become extinct
(E) expand the definition of “hot spot” to include vulnerable habitats that are not currently home to many endangered species

GMATNinja could you please help me understand why option 'A'is wrong?

(C) treat all endemic species as equally valuable and equally in need of preservation

(E) expand the definition of “hot spot” to include vulnerable habitats that are not currently home to many endangered species



Let me take a shot at it. I was confused between A and B too.

(A) try to help only those species who are threatened with extinction because of habitat loss

The key here is staying in context of the stimulus. The stimulus describes what a hot spot is and why it is important. (B) logically completes the argument by protecting hotspots (from encroachment) and thereby protecting endemic species from extinction. In the case of (A), it just generally mentions about protecting those species threatened with extinction because of habitat loss.
2 questions arise:
1. Why no context of hot spots? Habitat loss might be occurring in areas other than hot spots as well. If that's the case, concentrating efforts in multiple areas would mean waging a ton of environmental battles.
2. Species threatened with extinction might be anywhere and everywhere. You cannot be waging limited environmental battles going after all of them.

(B) concentrate their resources on protecting hot spot habitats
(C) treat all endemic species as equally valuable and equally in need of preservation
(D) accept that most endemic species will become extinct
(E) expand the definition of “hot spot” to include vulnerable habitats that are not currently home to many endangered species

Argument:

Hot spots house endemic species (species found only in one place).
Hot spots are vulnerable to habitat loss due to commercial development.
Loss of endemic species accounts for most modern-day extinctions
Only a limited number of environmental battles can be waged

So, it would be reasonable for organisations dedicated to preserving species to _______.

What would be the logical course of action for the organisations to preserve species? They should focus on saving the hotspots. That is where endemic species live and if hot spots are lost, the species will be lost.
Answer (B)

VeritasKarishma thank you for your explanation.

While solving the question I thought that the sentence meant that it is very difficult to save the hotspots, considering that only a limited number of environmental battles can be waged, and therefore, the author should accept that the endemic species will become extinct.
I remember studying your explanation from another question which said that we should only focus on what we can do - therefore, since we know that we can only fight a limited number of environmental battles, we should also accept that the species will go extinct.

Could you please explain how did you eliminate option B?

Thank you!

The argument says, "Only a limited number of environmental battles can be waged". It does not say, "Only a limited number of environmental battles for hotspots can be waged."

The point he is trying to make is that hotspots are important since most to-be-extinct species are there. So use your limited resources to save them. Since limited number of environmental battles can be waged, let those battles be waged against conversion of hotspots.

Help is a broad word compared to Protect which directly delivers the meaning.
