Seemingly inconsequential changes in sea temperature due to global warming eventually result in declines in fish and seabird populations. A rise of just two degrees prevents the vertical mixing of seawater from different strata. This restricts the availability of upwelling nutrients to phytoplankton. Since zooplankton, which feed upon phytoplankton, feed the rest of the food chain, the declines are inevitable.

Which of the following most accurately describes the role played in the argument by the statement that zooplankton feed upon phytoplankton ?

A. It is a hypothesis supported by the fact that phytoplankton feed on upwelling nutrients.
B. It is intended to provide an example of the ways in which the vertical mixing of seawater affects feeding habits.
C. It helps show how global temperature changes affect larger sea animals indirectly.
D. It is offered as one reason that global warming must be curtailed.
E. It is offered in support of the idea that global warming poses a threat to all organisms.

Dear BrainLab,
I'm happy to respond. :-) This question really doesn't have the feel of an official GMAT CR question.

The argument has a formal structure of A leads to B, B leads to C, C leads to D, and the statement in question is one of these links.
(A) it is not an hypothesis
(B) it is not an example
(C) promising
(D) & (E) zooplankton feeding phytoplankton is part of the nature cycle: this phenomenon is not a problem!

The detail is mentioned in the context of demonstrating how changes in patterns of upwelling nutrients eventually impact microscopic sea life. In other words, it helps us understand how global temperature changes affect larger sea animals indirectly. This is precisely what (C) says.

Does this make sense?
Mike :-)

Hi Mike, thanks for the response, nice explanation. I've answered this question correctly, I agree with you, it's not a 100% Gmat like question, it's from CR Bible, and they usually post LSAT questions.

Here is my solution:

Rise of 2 degrees --> affects vertical mixing of sea water --> affects upwelling nutrients to Phytoplankton --> affetcs Zooplanktion, as it feeds upon Phyto.. --> affects the whole food chain --> (restating the conclusion at the begining) declines are inevitable (declines seabird and seabird population)

A. It is a hypothesis supported by the fact that phytoplankton feed on upwelling nutrients. --> it's not a hypothesis/conclusion
B. It is intended to provide an example of the ways in which the vertical mixing of seawater affects feeding habits. --> this argument is intended to provide that rise of just 2 degrees affects ...
C. It helps show how global temperature changes affect larger sea animals indirectly. --> CORRECT. That's the first element in my reasoning chain state above
D. It is offered as one reason that global warming must be curtailed. --> it's not stated in the argument that some actions should be maintained against global warming
E. It is offered in support of the idea that global warming poses a threat to all organisms[/color]. --> it's TOO extreme, the argument is talking about some seabirds and fishes and not about ALL organisms

Hi mikemcgarry,

Thanks for your input. Just a quick question,
In the last line of the argument it mentions "feed the rest of the food chain", can "rest of the food chain" imply "to all organisms" mentioned in E?

Thanks and Regards

Dear rezwan001,

I'm happy to respond. :-)

The answer is no. Think about it this way. We don't need to know advanced biology, but we just need to think about some basic everyday facts.

What do you and I, as humans, eat? We eat plants and animals. The land plants we eat are not part of the food chain that begins with phytoplankton. The land animals we eat in turn eat land plants, so they are not part of that food chain either. Now, if we eat fish or other sea critters, that might be part of a food chain that include the phytoplankton. But if for some reasons, all humans everywhere had to stop eating all food from the sea, of course some people would be disappointed, but the human race as a whole would not die off even if we all had to stop eating sea food. There are large quantities of land plants and land animals that can keep at least most of the human race still alive, even with the total absence of sea food. Therefore, we, and the land animals & plants, are not part of the food chain that depends on the phytoplankton, and the "rest of the food chain" is not synonymous with "all organisms."

Does all this make sense?
Mike :-)

Seemingly inconsequential changes in sea temperature due to global warming eventually result in declines in fish and seabird populations. A rise of just two degrees prevents the vertical mixing of seawater from different strata. This restricts the availability of upwelling nutrients to phytoplankton. Since zooplankton, which feed upon phytoplankton, feed the rest of the food chain, the declines are inevitable.

The boldface portion plays which one of the following roles in the argument?

A. It is a hypothesis supported by the fact that phytoplankton feed on upwelling nutrients.
B. It is intended to provide an example of the ways in which the vertical mixing of seawater affects feeding habits.
C. It helps show how global temperature changes affect larger sea animals directly.
D. It is offered as one reason that global warming must be curtailed.
E. It is offered in support of the idea that global warming poses a threat to all organisms.

Question explanation:

(A): The portion referenced in the question stem is not a hypothesis, but rather a statement of fact.
(B): The statement referenced in the question stem is not an example of the way the mixing of seawater affects feeding habits, but rather another premise that is then combined with the vertical mixing premise to help support the conclusion.
(C): This is the correct answer. The phrase “it helps show” describes a premise, and in this case the premise is used to support a statement about
the effect of temperature changes on fish and seabirds.
(D): The argument does not take a position that global warming should be curtailed. Instead, the argument shows how small changes in sea temperature lead to population declines, and no opinion of those effects is stated.
(E): This is an Exaggerated Answer. The argument specifically indicates that fish and seabirds populations will decline. This answer choices states that all organisms are threatened.
