GMAT (Graduate Management Admission Test)

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.

1. Advertisement: Today's clients expect top quality. Every improvement in the standards of service raises client
expectations. The company that is complacent and satisfied with the current quality of its products will soon find
that its clients are not. At Service Enterprises, meeting or exceeding client expectations is our goal.
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!

@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.

@avik.ch yo can only question the conclusion derived from a premise and yo can never question a premise in GMAT even if we know that the premise has a flaw.. Premises are undisputed facts that can never be questioned.

Never question the premise.

@avik.ch i think the answer shd be "E" cause here the argument scope is limited with aerobic and resistive training. the claim is of aerobic training being best bet to reduce fat compared to resistive training and not compared to all the trainings there in the world for that matter. by that standard option A is out of scope...option E is well within the scope and tries to negate the argument by showing that the data used is inappropriate/insufficient to draw conclusion.As far as option A and E are compared, both are claims without justification.

Thanks @avik.ch. In your explanation, yo said like the argument gets weakened if the validity is proved false. Isnt wat they did in choice E?. they say like the X's research is not yet verified.

Hi all, I am bit confused with the CR question I read in a forumThe question is"A recent study has found that aerobic exercising is the best bet to reduce fat compared to resistive training. A research center X had done a head-to-head comparison on aerobic training, resistive training, combo of both and found thataerobic exercising is the most efficient and effective way to reduce one's belly fat. Aerobic exercise reduce 70% more calories compared to resistance training.Which of the following if true, weakens the argument?A. Pilates training, if done for regularly for 6 months can be more effective than the aerobic trainingB. Aerobic exercise, if done without proper training can lead to injuries in neck and back bone.C. 70 % of the people who reduce fat by aerobic training have gained weight in the next 6 monthsD. Aerobic training if not combined with resistive training can reduce the muscle's strength.E. Research center X's study has not been verified independently. Although, the sample were from diverse communities, the total number of people were not enough to draw a conclusion"The answer is A. I'm confused why not E. What if the research center study is flawed.

@EducationAisle CAN YOU SUGGEST ME SOME GUD CHALLENGING MATERIAL FOR CRITICAL REASONING, i have my thinking in line,but very less material with me so far as i was into CAT n all that stuff....

now i want to kickstart GMAT...
