Directiоns: Belоw is the beginning оf аn essаy titled “The Plot Agаinst People” by New York Times columnist Russell Baker. After reading the passage, click on the statements which are most logically supported by the information given. inanimate: lifeless idle: not busy classified: grouped cunning: slyness (1)Inanimate objects are classified scientifically into three major categories—those that break down, those that get lost, and those that don’t work. (2)The goal of all inanimate objects is to resist man and ultimately to defeat him, and the three major classifications are based on the method each object uses to achieve its purpose. (3)As a general rule, any object capable of breaking down at the moment when it is most needed will do so. (4)The automobile is typical of this category. (5)With the cunning peculiar to its breed, the automobile never breaks down while entering a filling station which has a large staff of idle mechanics. (6)It waits until it reaches a downtown intersection in the middle of the rush hour, or until it is fully loaded with family and luggage on the Ohio Turnpike. (7)Thus it creates maximum inconvenience, frustration, and irritability. . . . (8)Many inanimate objects, of course, find it extremely difficult to break down. (9)Pliers, for example, and gloves and keys are almost totally incapable of breaking down. (10)Therefore, they have had to evolve a different technique for resisting man. (11)They get lost. (12)Science has still not solved the mystery of how they do it, and no man has ever caught one of them in the act. Which statement is logically supported by this passage?

(2)Druggists who sold contraceptive devices were arrested. (3)Various states had their own legislation concerning contraception. (4)Some made it a crime to distribute contraceptive literature. (5)Others forbade physicians to prescribe contraceptive devices. (6)Some even (as in Connecticut) made it against the law for couples—single or married—to use contraceptive devices. (7)Many of these anticontraceptive measures continued into the present century, some until recently. (8)The clergy denounced birth control as sinful. (9)Theodore Roosevelt warned of “race suicide.” (10)Condoms were referred to as “rubber articles for immoral use.” (11)In the 1920s, the birth-control-movement leader Margaret Sanger needed diaphragms to distribute to women who came to her birth-control clinic. (12)She was unable to obtain such contraceptives in the United States and had to purchase them from abroad. (13)American manufacturers were by then permitted to manufacture contraceptive devices. (14)But they refused to make the reliable Mensinga diaphragm and, instead, made unsatisfactory cervical caps. (15)However, it was illegal to import contraceptives. (16)Margaret Sanger’s clinic therefore obtained them through illegal channels. (17)The diaphragms were imported from Germany by way of Canada and then smuggled across the border in oil drums. The passage clearly implies that in the 1920s,
