I think 12th question answer should be C instead of E if we think about the lines in last paragraph .

6 Mins :o that's awesome!! To read the paragraph itself it took 6 mins for me :P Any tips sir..

I took 12 minutes, all correct.. Yes, last one should be C.

- Read question first - Ignore all the relative clauses , dependent clauses and Examples ; Make structure words exception . Map the paragraph in maximum 4 - 5 words .
General question - guess first
Detail question - use map to come to parah and check
Well i guess this is what a GMAT preparing guy should do. Rather than understanding whole parah and answering form memory.
Think RC is BIG CR question, where background info plays no role.

normally, there are 3 wrong answer which are clear because all of long phrase is incorrect

when there are 2 choices left, the wrong choice has only ONE WORD WRONG.

choice B and C are close. choice b has ONE WORD WRONG which is "one stream".

so B is wrong

when facing two closes answers, find out ONE WORD WRONG.

Please comment!!

Dear tae808,

I'm happy to respond my friend. :-)

A "habitat" is the environment in which a living thing is designed to live, the place where it naturally thrives. For a deer, the habitat is a forest. For a giraffe, the habitat is the Serengeti. For a salmon, the habitat, for at least part of its life cycle, is a stream. Many things live in a healthy stream, so for these animals, it is a habitat. Does this make sense?

Mike


Dear Mike,
Hope you can help with this question

6. Which of the following does the author mention as support for the view that environmental disturbances caused by human activity could increase straying rates?

(A) The existence of salmon populations in rivers where the elimination of salmon habitat by human activity had previously made the fish extinct
(B) The results of studies measuring the impact on straying rates of habitat loss caused by human activity
(C) The potential for disturbances in one environment to cause the introduction of novel genes into salmon populations in neighboring areas
(D) The weaknesses in the view that the extinction of entire salmon populations is the only mechanism by which human destruction of salmon habitat reduces genetic diversity in salmon
(E) The absence of any reason for believing that disturbances brought about by human activitiy would differ in their effects from comparable disturbances brought about by natural causes

I cannot find any support for option D.
No where in the passage does it say or imply " elimination of entire salmon population is the only way that leads to reduction in genetic diversity"

So the question of weakness in this view does not arise.

I thought answer for this question should be E.

May be I am missing something. Thanks for your help.

I'm also having trouble with this one. This is probably wrong but this is the only way I can make the OA fit.

(D) The weaknesses in the view that the extinction of entire salmon populations is the only mechanism by which human destruction of salmon habitat reduces genetic diversity in salmon

what are the weaknesses mentioned?

There is only one as far as I can tell and that is by introducing another possible mechanism by which human destruction of Salmon habitat could reduce genetic diversity. Severe disturbances caused by natural disasters have led to an increase in straying which could limit genetic diversity if as indicated the fish that stray interbreed with the existing stock to such a degree that any local adaptations that are present become diluted. It then goes on to say that environmental disturbances caused by human destruction would likely have the same effect (the reason for the confusion with E.)

So what supports the idea that environmental disturbances caused by human activity could increase straying rates? (D) The fact that environmental disturbances caused by natural disasters have lead to an increase in straying.


(E) The absence of any reason for believing that disturbances brought about by human activity would differ in their effects from comparable disturbances brought about by natural causes

My thinking is that E. might need to be combined with D. for it to be in support and so not correct.

I really hope one of the experts could explain the logic behind this question.

E is clearly wrong because disturbances brought by human activity is indeed different from disturbances by natural causes,
D is correct because D says that the following reasoning is wrong: the disturbances by human activity is the only mechanism that eliminates entire population of the fish (in the first paragraph)
C is the trap that I still do not fully understand

The OA to question #6 appears to be incorrect. A report has been submitted to confirm/update the original post.

Thanks for your replies!

hello experts,

can you explain the answer for this question?

4. The author mentions the “aftermath of the Mount Saint Helens eruption” most likely in order to

(A) provide an example of the process that allows the repopulation of rivers whose indigenous salmon population has become extinct
(B) indicate the extent to which the disturbance of salmon habitat by human activity in one stream might affect the genetic structure of salmon populations elsewhere
(C) provide a standard of comparison against which the impact of human activity on the gene flow among salmon populations should be measured
(D) show how salmons’ homing instinct can be impaired as a result of severe environmental degradation of their natal streams
(E) show why straying rates in salmon populations remain generally low except when spawning streams suffer severe environmental disturbance

Hi Guys,

I found this passage extremely difficult.... Not able to eliminate answer choices for 4 out of 6 questions... And I took almost 14 mintutes of 6 question.

My worry is; what should be a strategy if this passage pops up in actual exam?

Thank you sir for this article.

Luckily I am following almost same strategy. Only issue is with RC initial passage reading. I take almost 4 minutes for easy passage and 4.5/5 minutes of difficult one such as this.

not sure If i can improve onto this .. If you can suggest your view here.
