Until the Federal government began providing low-cost flood insurance to coastal property owners, construction along beaches was limited by owners' fears that their property would be washed away. Since the insurance was made available, however, beachfront construction has boomed and therefore lan...

1) Prohibiting beachfront property owners from embellishing or adding to existing buildings
2) Utilizing computer science techniques to obtain detailed information on the extent and rapidity of land erosion along beaches
3) Enacting building codes requiring new beachfront structures in flood-threatened areas to be elevated above the high water level of a storm
4) Compensating beachfront property owners for moving to a new location off the coast while canceling flood insurance benefits for any new or remaining beachfront construction.
5) Requiring beachfront property owners receiving flood insurance coverage to adopt construction standards that will protect their buildings from inundation.

Recently, some critics of the U.S. government have pointed out that this country is the only advanced industrialized nation without a national vaccine laboratory and suggested that this lack makes the American public more vulnerable than other developed nations to infectious diseases, such as avian flu. A government official said these critics were disloyal and thus wrong about the public’s vulnerability. To support his claim, the official cited the generally long life span and low infant mortality of United States citizens, relative to all United Nation member nations. Mentioning the high quality of American hospitals, he added that all of the Europeans that he knew preferred to undergo major medical treatments in the United States rather than in the socialized medical systems in place in their home countries.

All of the following are weaknesses or potential weaknesses in the official’s argument EXCEPT:

• The high quality of hospitals in the United States is not a factor affecting the public’s vulnerability to infectious disease.

• Whether or not the critics are disloyal has no bearing on whether or not they are wrong.

• The Europeans that the official cited are a demographically narrow sample, overwhelmingly composed of wealthy males over the age of fifty.

• The average life span of United States citizens is determined not only by deaths due to infectious diseases but also by deaths due to all other causes.

• Comparing the United States to all United Nations member nations does not address the concern that the U.S. is behind other advanced industrialized nations in a particular way.

ron123 5th point brings out a totally different aspect by showing US to be far behind other nations in some respects. This analogy is no way related to the main argument. So I feel ans should be 5.

". Weakness should show official claim may be wrong. Since it is an except question answer choice should not contain anything related to Weakness in official's claim

Which of the following must be true on the basis of the statements in the advertisement above?
A. Service Enterprises' competitors will succeed in attracting customers only if those competitors adopt Service
Enterprises' goal as their own.
B. A company that does not correctly anticipate the expectations of its customers is certain to fail in advancing
the quality of its products.
C. Service Enterprises goal is possible to meet only if continuing advances in product quality are possible.
D. If a company becomes satisfied with the quality of its products, then the quality of its products is sure to
decline.
E. Service Enterprises' customers are currently satisfied with the quality of its products

I feel its C! i didnt find the answer to this when this was posted earlier!

well this is a must be true question and so first define the scope of the argument and then move on....

A confuses between necessary and sufficient condition, be wary of this kind of choices. Moreover, discussion about competitor is well outside the scope.

B - the arg scope is for companies that anticipates customer expectation - so those who do not is too outside the scope.

D - its a distortion. if the company is satisfied with its produce, its product will soon be perceived as "not satisfactory and good quality" by its customer. So eliminate this - as the argument talks about the "perceived quality" while this option talks about the "absolute quality"

E - there is a difference between a "goal" and what is "achieved". Eliminate.

left with C ---- apply denial test to prove the statement - an inference when negated will not have any value towards the argument. ( but this should be done only when there are 2-3 left which you cannot eliminate ) -

Service Enterprises goal is not possible to meet only if continuing advances in product quality are possible --- woah !! this is exactly opposite to what the argument states !!

hope this helps !!

@avik.ch your knowledge is badly needed for this question...

Although fullerenes- spherical molecules made entirely of carbon-were first found in laboratory , they have since have been found in nature, formed in fissures of the rare mineral Shungites. since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the earth's crust at the time these naturally occuring fullerenes were formed.

Which of the following ,if true, most seriously undermines the argument?

1. confirming that the Shungite genuinely contained fullerenes took careful experimentation.

2. Some fullerenes have also been found in the remains of a meteorite that collided with a spacecraft.

3. The mineral shungite itself contains large amounts of carbon, from which the fullerenes apparantly formed.

4. The naturally occuring fullerenes are arranged in a previously unknown crystalline structure.

5. Shungite itself is formed under distinctive conditions.

Please explain...thanks in advance.

hi, this is a gmat prep question and hence has been discussed many times in many diff forums ---

so here I am quoting a reply from the great Testluv, a kaplan instructor

[ The author's evidence has established that the labaratory conditions leading to fullerenes are unique. He also tells us that we have now found fullerenes in nature (shungite stuff is red herring).

He is arguing that because lab-fullerene-formation requires unique conditions, we can examine these new natural fullerenes to figure out what the conditions in the Earth's crust were like back when these fullerenes were formed.

He is assuming that fullerenes everywhere (ie, the naturally occuring ones, outside of the labaratory) also come about through unique conditions. (It might just be the case that it is only in the labaratory that unique conditions are required or that they have yet to hit upon other ways of making fullerenes in the lab).

We can use the Kaplan denial test to verify whether we have figured out the assumption correctly: what if, outside of the lab, there are many ways that fullerenes can be formed? Then, what happens to the argument that we can examine these naturally ooccuring fullerenes to figure out what the conditions were like when they were formed? Well because there are many was they could have formed, and who knows what the conditions were like back then: the argument now falls apart. Therefore, we have properly identified a necessary assumption.

..now (and only now) are we ready to go to the answer choices.

Because this is a weaken question, we look for a choice that attacks this assumption. Choice D opens up the possibility of fullerenes forming in ways unknown in the lab, and is correct.

In a harder argument, it is very important to resist the temptation to go to the answer choices prematurely. Gotta analyze the stimulus and figure out how, precisely, the evidence is not good enough to estalish the conclusion. Gotta figure out that assumption!

Make sure you always ask what idea is in the conclusion that is not in the evidence and what idea is in the evidence that is not in the conclusion, and then bridge the gap. This is the classic Kaplan method for arguments.

Applied here:

What idea is in the evidence that is not in the conclusion? "lab fullerenes"

And the idea in the conclusion that is not in the evidence? "naturally occuring fullerenes".

Then bridge the gap: "The author is assuming some sort of similarity between the two. The argument is about unique conditions, so he is assuming that conditions are unique for both lab and natural fullerenes." ] - Testluv

ankur_jaini I feel, the answer should be 4. The state of the earth's crust is being determined by the structure of fullereness. And 4 says that naturally occurring fullereness differs from the one being systhesized in lab. Thus, stats available for the lab systhesized fullereness cannot be used against the naturally ouucrring ones to determine info about earth's crust

scrabbler I feel 2...if they were found in a meteorite, then it may be that even the ones on Earth came from some meteorite...in which case they might not be giving info about the state of the Earth's crust at the time but about the meteorite instead!

scrabbler

#2 • 7d ago Like
ankur_jaini umm..You have a point here
But, the statement says we are considering how "naturally" occurring were/are fullerenes . So, i feel we should not consider the fact if fullerenes have come from meteorite.
Secondly, 4th one hits the premise directly that the structure is different. So, 4 still seems more apt to me.
Lemme know your views.
