The Quantitative Reasoning questions cover topics like number properties, algebra, coordinates, permutation and combination, arithmetic word problems – percentages, time and distance, etc. Both PS and DS types have been included. The Verbal reasoning section consists of questions on Sentence correction and Critical reasoning. Some of the questions have been developed inhouse and some borrowed from different sources on GMATclub (which are widely available).

A new test for AIDS has proved helpful in eliminating blood, contaminated with the virus, from the nation’s blood supply.
Some animals, such as dolphins, dogs, and African grey parrots, seem to exhibit cognitive functions typically associated with higherorder primates such as chimpanzees, gorillas, and humans. Some parrots, for example, have vocabularies of hundreds of words that they can string together in a comprehensible syntax. This clearly shows that humans and primates are not the only animals capable of using language to communicate. One parrot, named Alex, has been known to ask to be petted or kissed and will exhibit aggression if the gesture offered is not the specific one requested.
Which of the following, if true, would most strengthen the conclusion above?
Antarctic seals dive to great depths and stay submerged for hours. They do not rely solely on oxygen held in their lungs, but also store extra oxygen in their blood. Indeed, some researchers hypothesize that for long dives these seals also store oxygenated blood in their spleens.
Each of the following, if true, provides some support for the researchers’ hypothesis EXCEPT:
Five years ago, during the first North American outbreak of the cattle disease CXC, the death rate from the disease was 5 percent of all reported cases, whereas today the corresponding figure is over 18 percent. It is clear, therefore, that during these past 5 years, CXC has increased in virulence.
Which one of the following, if true, most substantially weakens the argument?
One year ago a local government initiated an antismoking advertising campaign in local newspapers which it financed by imposing a tax on cigarettes of 20 cents per pack. One year later the number of people in the locality who smoke cigarettes had declined by 3 percent. Clearly, what was said in the advertisements had an effect, although a small one, on the number of people in the locality who smoke cigarettes.
Which one of the following, if true, most helps to strengthen argument?
The noise caused by airplanes during takeoff and landing imposes a large burden on people who live or work near airports. When airports operate late at night or early in the morning, the disturbance can disrupt normal sleeping patterns, even leading to severe sleep deprivation disorders. When the flight paths of airplanes lie too close to the ground, the resulting noise interferes with work performance in nearby businesses and the peaceful enjoyment of life by residents in the proximity. However, the operation of an airport, unlike a neighbor who simply plays music too loudly, provides a valuable benefit to the surrounding community, in the form of convenient transportation for both personal and economic purposes. Thus the only option is to establish standards for the reasonable operation of airports and fine those that violate the guidelines.
The bolded phrase plays which of the following roles in the argument above?
