İsim Soyisim E-Posta Telefon Q. 1 In the past, consumers would rarely walk into an ice cream store and order low-fat ice cream. But that isn't the case today. An increasing health consciousness combined with a much bigger selection of tasty low-fat foods in all categories has made low-fat ice cream a very profitable item for ice cream store owners.This paragraph best supports the statement thatDeselect Answer low-fat ice cream produces more revenue than other low-fat foods. ice cream store owners would be better off carrying only low-fat ice cream. ice cream store owners no longer think that low-fat ice cream is an unpopular item. low-fat ice cream is more popular than other kinds of ice cream consumers are fickle and it is impossible to please them None Q. 2 Many scientific studies have found links between genius and mental illness, particularly bipolar disorder in which patients have violent mood swings between elation and depression. In one interesting Swedish study, 700,000 Swedes had intelligence tests at age 16 and again 10 years later. Those who scored well were four times more likely than the others to have developed bipolar disorder. The US neurologist James Fallon came up with a convincing argument based on his own findings in the field: the brain area involved in mood swings is the same area where creativity is born. This may explain why some people can draw previously unseen connections among ideas, images, shapes and the like.Which of the following is inferred from the above?Deselect Answer Those with bipolar disorder are likely to be highly intelligent. Most people who excel in creativity are likely suffering from a mental problem. Bipolar disorder can be good for many ways. Often there is a correlation between mental illness and genius. Mental disorders give birth to genius. None Q. 3 More and more computer software that is capable of correcting not just spelling, but also grammar and punctuation is being developed. Therefore, it is increasingly unnecessary for working reporters and writers to have a complete knowledge of the principles of English grammar and punctuation. Consequently, in training journal- ists, less emphasis should be placed on the principles of grammar so that students and professors can concentrate on other important subjects. Which one of the following, if true, most seriously weakens the argument given for the recommendation above?Deselect Answer The effective use of software that corrects grammar and punctuation requires an understanding of grammatical principles. Much of the software that corrects grammar and punctuation is already in use. Development of more complex ethical guidelines for reporters and writers has meant that professors and students in journalism schools must allow time for teaching such issues. Most of the software that is capable of correcting grammar and punctuation can be run on the types of computers available to most media outlets. The journalism curriculum already requires that journalism students be familiar with, and able to use, a variety of software packages. None Q. 4 Physician: The continued use of this drug to treat patients with a certain disease cannot be adequately supported by the proposition that any drug that treats the disease is more effective than no treatment at all. What must also be taken into account is that this drug is very expensive and has notable side effects. Which one of the following most accurately expresses the main point of the physi- cian’s argument?Deselect Answer The drug is more effective than no treatment at all. The drug is more effective than other forms of treatment for the disease. The drug is more expensive than other forms of treatment for the disease. The drug should not be used to treat the disease unless it is either effective or inexpensive. The drug’s possible effectiveness in treating the disease is not sufficient justification for using it. None Q. 5 It is widely accepted that eating sugar can cause weight gain. Indeed, many people who are susceptible to weight gain report that, in their own experience, eating large amounts of sugar is invariably followed by a measurable weight gain within a few days. However, it is likely that common wisdom has confused cause and effect. Recent studies suggest that hormonal changes associated with stress can cause weight gain, and there is ample evidence that people who are fond of sugar tend to eat more of it when they are under stress. The argument employs which one of the following argumentative strategies?Deselect Answer It cites evidence that questions the accuracy of the evidence advanced in support of the position that is being called into question. It gives additional evidence that suggests an alternative interpretation of the evidence offered in support of the position being challenged. It relies upon the superiority of science versus common opinion as a means of dismissing the relevance of evidence based upon common experience. It shows that the position being challenged is not consistent with cited, proven factual evidence. It calls into question the intelligence of those who subscribe to a certain popularly held belief None Q. 6 From a group of seven people—J, K, L, M, N, P, and Q—exactly four will be selected to attend a diplomat’s retirement dinner. Selection conforms to the following conditions: Either J or K must be selected, but J and K cannot both be selected. Either N or P must be selected, but N and P cannot both be selected. N cannot be selected unless L is selected. Q cannot be selected unless K is selected. There is only one acceptable group of four that can be selected to attend the retirement dinner if which one of the following pairs of people is selected?Deselect Answer J and L K and M L and N L and Q M and Q None Q. 7 Pinky is standing in a queue at a ticket counter.

When he bought the books in the first shop, he was given a loyalty card. For every full $10 that he has spent he will get $1 he can use when he buys more books. However, the first shop has reduced its discount to 10% before that offer. The second shop has charged its discount offer to $9 off any purchase totaling $60 or more. The third shop has applied 15% off any book that normally cost $20 or more. John still wants to buy all four books from the same shop. What is the cheapest amount he could pay for them?Deselect Answer 59 60 61 62.25 63.25 None Q. 10 The shapes from the game Tetris are sometimes called ‘tetrominoes’.

Approximately two liters of liquid and nutrient waste are excreted as urine. The remaining fluid and dissolved substances are reabsorbed and continue to circulate throughout the body. Antidiuretic hormone (ADH) is secreted in response to reduced plasma volume. ADH targets the collecting ducts in the kidney, stimulating the insertion of aquaporins into their plasma membranes and an increased reabsorption of water. If ADH secretion is inhibited, which of the following would initially result?Deselect Answer The number of aquaporins would increase in response to the inhibition of ADH. The person would decrease oral water intake to compensate for the inhibition of ADH. The person would produce greater amounts of dilute urine.
