The imposition of quotas limiting imported steel will not help the big American steel mills. In fact, the quotas will help "mini-mills" flourish in the United States. Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas.
Which of following, if true, would cast the most serious doubt on the claim made in the last sentence above?
A. Quality rather than price is a major factor in determining the type of steel to be used for a particular application B. Foreign steel mills have long produced grades of steel comparable in quality to the steel produced by the big American mills C. American quotas on imported goods have often induced other countries to impose similar quotas on American goods D. Domestic "mini-mills" consistently produce better grades of steel than do the big American mills E. Domestic "mini-mills"produce low-volume, specialized types of steel that are not produced by the big American steel mills

40. (#32847)
A recent report determined that although only 3% of drivers on Maryland highways equipped their vehicles with radar detectors, 33% of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.
The conclusion drawn above depends on which of the following assumptions?
A. Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not B. Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed C. The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detector D. Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report E. Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report
