1. The excessive number of safety regulation that the federal government has placed on industry poses more serious hardships for big businesses than for small ones. Since large companies do everything on a more massive scale， they must alter more complex operations and spend much more money to meet governmental requirements.
Which of the following ， if true， would most weaken the argument above？
（A） Small companies are less likely than large companies to have the capital reserves for improvements.
（B） The operation codes are uniform， established without reference to size of company.
（C） Safety regulation codes are uniform， established without reference to size of company.
（D） Large companies typically have more of their profits invested in other businesses than do small companies.
（E） Large companies are in general more likely than small companies to diversify the markets and products.
2. Banning cigarette advertisements in the mass media will not reduce the number of young people who smoke. They know that cigarettes exist and they know how to get them. They do not need the advertisements to supply that information.
The above argument would be most weakened if which of the following were true？
（A） Seeing or hearing an advertisement for a product tends to increase people’s desire for that product.

（C） Advertisements in the mass media have been an exceedingly large part of the expenditures of the tobacco companies.
（D） Those who oppose cigarette use have advertised against it in the mass media ever since cigarettes were found to be harmful.
（E） Older people tend to be less influenced by mass-media advertisements than younger people tend to be.
3. The average normal infant born in the United States weighs between twelve and fourteen pounds at the age of three months. Therefore， if a three-month-old child weighs only ten pounds， its weight gain has been below the United States average.
Which of the following indicates a flaw in the reasoning above？
（A） Weight is only one measure of normal infant development.
（B） Some three-month-old children weigh as much as seventeen pounds.
（C） It is possible for a normal child to weigh ten pounds at birth.
（D） The phrase “ below average” does not necessarily mean insufficient.
（E） Average weight gain is not the same as average weight.
4. According to a recent survey， marriage is fattening. Cited as evidence is the survey’s finding that the average woman gains 23 pounds and the average man gains 18 pounds during 13 years of marriage.
The answer to which of the following questions would be most relevant in evaluating the reasoning presented in the survey？ （A） Why was the period of time studied in the survey 13 years， rather than 12 or 14？
（B） Did some of the men surveyed gain less than 18 pounds during the time they were married？
（C） How much weight is gained or lost in 13 years by single people of comparable age to those surveyed？
（D） Were the women surveyed as active as the men surveyed， at the time the survey was made？
（E） Will the reported gains be maintained over the lifetimes of the persons surveyed？
5. The cost of the average computer logic device is falling at the rate of 25 percent per year， and the cost of the average computer memory device at the rate of 40 percent per year. It can be concluded that if these ratess of cost decline remain constant for a period of three years， at the end of that time the cost of the average computer memory device will have declined by a greater amount than the cost of the average computer logic device.5.
Accurate information about which of the following would be most useful in evaluating the correctness of the conclusion above？ （A） The number of logic devices and memory devices projected to be purchased during the next three years
（B） The actual prices charged for the average computer logic device and the average computer memory device
（C） The compatibility of different manufacturers’ logic devices and memory devices
（D） The relative durability of logic devices and memory devices
（E） The average number of logic devices and memory devices needed for an average computer system
6. The population of peregrine falcons declined rapidly during the 1950’s and 1960’s and reached an all-time low in the early 1970’s. The decline was attributed by scientists to the widespread use of the pesticide DDT in rural areas.
Which of the following， if true， gives the strongest support to the scientits claim？
（A） DDT was not generally in use in areas devoted to heavy industry.
（B） In the time since the use of DDT was banned in 1972， the population of peregrine falcons has been steadily increasing. （C） Peregrine falcons， like other birds of prey， abandon eggs that have fallen out of the nest， even if the eggs remain intact.
（D） Starlings， house sparrows， and blue jay-birds the peregrine falcon prey on-were not adversely affected by DDT in their habitats.
（E） Other birds of prey， such as the osprey， the bald eagle， and the brown pelican， are found in the same areas as is the peregrine falcon.
7. The price of maple syrup has jumped from 22 dollars three years ago to 40 dollars a gallon today. It can be concluded that maple-syrup harvesters have been artificially inflating prices and that governmental price regulations are necessary to control rising prices.Which of the following， if ture， casts the most doubt on the conclusion drawn above？
（A） The government already requires maple-syrup harvesters to submit their facilities to licensing by the health department. （B） Insect infestation and drought have stunted the growth of syrupproducing maple trees and caused less-abundant syrup harvests.
（C） Maple syrup is produced in rural areas that suffer from high unemployment.
（D） Technological improvements in maple-syrup harvesting have reduced production costs.
（E） Maple-syrup prices have risen many times in the past， though never before at the rate recently observed.
8. Artificial seaweed made of plastic has been placed on a section of coast in order to reverse beach erosion. The inventor of the seaweed has concluded that the recent buildup of sand on that section of coast proves that the artificial seaweed reverse beach erosion.Which of the following， if true， would most seriously weaken the inventor’s conclusion？
（A） The amount of recent sand buildup on that section of coast was less than had been predicted on the basis of the results obtained in controlled experiments.
（B） Because artificial seaweed would be buried eventually by additional sand deposits on the coast， more artificial seaweed would need to be put in place every four years.
（C） Artificial seaweed of another material which had been previously developed by the inventor failed to add sand to coastline in past trials.
（D） The amount of recent sand buildup on that section of coast is the same as the amount of recent sand buildup on otherwise very similar section of coast without artificial seaweed.
（E） The amount of recent sand buildup on that section of coast， although considerable， is not yet enough to replace the amount lost during storms on that section of coast in the last twenty years.
9. The presence of microorganisms that produce a toxin causes seawater to turn brownish red， phenomenon known as a red tide. Sea otters do not feed in areas where clams， their main source of food， have become contaminated with this toxin. According to a proposed explanation of the otters’ behavior， the otters sample the clams in a potential feeding areas and can taste any toxin in them.
Which of the following， if true， would most strongly indicate that the hypothesis described in the last sentence of the passage is not correct？
（A） In some of the areas where red tides occur， neither clams nor sea otters are indigenous species.
（B） The presence of sea otters in a given areas has a significant effect on which other marine organisms are to be found in that area.
（C） When seawater in an area unaffected by red tide is artificially dyed brownish red， sea otters do not feed on the clams in that area.
（D） If the clams in a given area are contaminated with toxins， sea otters move to other areas in search of food.
（E） Although very small amounts of the toxin produced during a red tide are not harmful， large doses can be fatal to animals the size of sea otters.
10. Since 1945 there have been numerous international confrontations as tense as those that precipitated the Second World War， and yet no large-scale conflict has resulted.
