Question 20. Question : 11{7[1(01)77]} Detective: The robbery at the mall was carried out by a mall employee acting alone roughly one hour after the mall closed last Saturday night. The only employees present at the mall at the time of the robbery were security guards Evans and Clark. Since the mall’s surveillance system was disabled by the thief just before the robbery, the thief must be Evans. The argument above would be valid if: Student Answer: Clark is incapable of disabling the mall’s surveillance system. both Evans and Clark are capable of disabling the mall’s surveillance system. Evans and Clark are the mall’s only security guards. the mall’s surveillance system is usually used 24 hours a day, seven days a week. Points Received: 1 of 1 Comments: Question 21. Question : 11{7[3(08)84]} The president spoke to 19 congressmen from Texas to encourage them to vote for a bill. Since four of the 19 congressmen went on to vote for the bill, it is clear that the president persuaded those four to vote the way they did. The argument above assumes that: Student Answer: The bill will not pass because a majority of Texas congressmen did not vote for it. the Texas congressmen who voted against the bill were persuaded by someone other than the president to vote the way they did. The president did not try to influence the votes of any congressmen outside of Texas. The four Texas congressmen who voted for the bill were against it before they spoke to the president.

Question : 11{7[2(03)79]} Looking to increase the profits of his lemonade stand, Johann doubled the price of a cup of lemonade from 25 cents to 50 cents. This clearly shows Johann’s lack of business sense, for now he’ll almost certainly sell fewer cups at the new price and therefore make less money than before. The argument above assumes that: Student Answer: Johann is looking to double the profits of his lemonade stand. the price increase will likely put Johann out of business. profits from the price increase will not offset the money lost when fewer cups are sold even if Johann sells more cups at the new price than he did at the old price, he’ll still lose money on the lemonade stand.
