question:Motor oil serves to lubricate engines and thus retard engine wear. A study was conducted to assess the effectiveness of various brands of motor oil by using them in taxicabs over a 6, 000mile test period. All the oils did equally well in retarding wear on pistons and cylinders, the relevant parts of the engine. Hence, cheaper brands of oil are the best buys. Which one of the following, if true, most weakens the argument? A: The lubricating properties of all motor oils deteriorate over time, and the rate of deterioration is accelerated by heat. B: Cheaper brands of motor oil are often used by knowledgeable automobile mechanics for their own cars. C: Ability to retard engine wear is not the only property of motor oil important to the running of an engine. D: Tests other than of the ability to reduce engine wear also can reliably gauge the quality of motor oil. Choose A, B, C or D as your solution.

question:Jacqueline: I work one fulltime job. With this job, I can make my own hours and work more if I needed to. However, I want to get a second job to change things up a bit. The second job would be parttime and I could work it on the weekends.

Which one of the following principles, if valid, most helps to justify Jacqueline's reasoning? A: It is better to get a second parttime job because working on weekends does not bother Jacqueline. B: It is better to stay with the fulltime job and add more hours because it pays more. C: It is better to get a second parttime job, even if it pays less, for a mental change. D: It is better not to worry about making so much money; having freedom is the most important thing in life. Choose A, B, C or D as your solution.

question:Cooking teacher: Lima beans generally need about an hour of boiling to reach the proper degree of doneness. The precise amount of time it takes depends on size: larger beans require a longer cooking time than smaller beans do. It is important that lima beans not be overcooked since overcooking robs beans of many of their nutrients. Undercooking should also be avoided, since undercooked beans cannot be completely digested. If the statements above are true, they most strongly support which one of the following? A: Large lima beans, even when fully cooked, are more difficult to digest than small lima beans. B: Lima beans that are added to the pot together should be as close to the same size as possible if they are to yield their full nutritional value. C: The nutrients that are lost when lima beans are overcooked are the same as those that the body fails to assimilate when lima beans are not completely digested. D: Lima beans that are completely digestible have lost many of their nutrients in cooking. Choose A, B, C or D as your solution.
