However, since this new form of the fungus can be killed by increased application of currently used fungicides, it is unlikely that the fungus will cause widespread food shortages in countries that currently rely on potatoes for sustenance.Which of the following, if true, most calls into question the conclusion in the argument above? (A) Though potatoes are an important staple crop in many parts of the world, people in most countries rely primarily on wheat or rice for sustenance.(B) Potato farmers in many countries to which the new form of the fungus has spread cannot afford to increase their spending on fungicides. (C) The new form of the fungus first began to spread when contaminated potato seeds were inadvertently exported from a major potato-exporting country. (D) Potato farmers in most countries use several insecticides on their crops in addition to fungicides of the sort that kill the new form of the fungus. (E) Most governments have funds set aside that can be used to alleviate the effects of large-scale disasters such as severe food shortages and floods.2.As government agencies, faced with budget difficul- ties, reduce their funding for scientific research, a greater amount of such research is being funded by private foundations. This shift means that research projects likely to produce controversial results will almost certainly comprise a smaller proportion of all funded research projects, since private foundations, concerned about their public image, tend to avoid controversy. Which of the following is an assumption on which the argument depends? (A) Only research that is conducted without concern for the possibility of generating controversy is likely to produce scientifically valid results. (B) Private foundations that fund scientific research projects usually recognize that controversial results from those projects cannot always be avoided. (C) Scientists who conduct research projects funded by private foundations are unlikely to allow the concerns of the funding organizations to influ- ence the manner in which they conduct the research. (D) Many government agencies are more concerned about their public image than are most private foundations.(E) Government agencies are more willing than are private foundations to fund research projects that are likely to produce controversial results. 3.Juries in criminal trials do not base verdicts on uncor- roborated testimony given by any one witness. Rightly so, because it is usually prudent to be highly skeptical of unsubstantiated claims made by any one person. But then, to be consistent, juries should end an all- too-common practice: convicting defendants on the basis of an uncorroborated full confession. Which of the following, if true, most strengthens the argument above?(A) Juries often acquit in cases in which a defendant retracts a full confession made before trial. (B) The process of jury selection is designed to screen out people who have a firm opinion about the defendants guilt in advance of the trial. (C) Defendants sometimes make full confessions when they did in fact do what they are accused of doing and have come to believe that the prose- cutor has compelling proof of this. (D) Highly suggestible people who are accused of wrongdoing sometimes become so unsure of their own recollection of the past that they can come to accept the accusations made against them. (E) Many people believe that juries should not con- vict defendants who have not made a full con- fession. 4.Although spinach is rich in calcium, it also contains large amounts of oxalic acid, a substance that greatly impedes calcium absorption by the body. Therefore, other calcium-containing foods must be eaten either instead of or in addition to spinach if a person is to be sure of getting enough calcium.Which of the following, if true, most seriously weakens the argu-ment above? (A)Rice, which does not contain calcium, counteracts the effects of oxalic acid on calcium absorption. (B) Dairy products, which contain even more calcium than spinach does, are often eaten by people who eat spinach on a regularbasis. (C) Neither the calcium nor the oxalic acid in spinach is destroyed when spinach is cooked. (D) Many leafy green vegetables other than spinach that are rich in calcium also contain high concentrations of oxalic acid. (E) Oxalic acid has little effect on the bodys ability to absorb nutrients other than calcium.5.Joyce: Three years ago the traffic commission modified our towns busiest intersection for better visibility, a commendable effort to cut down on traffic accidents there.
