Philosophy student: If you accept that we were ought not to treat others in ways that we would not like to be treated, then you must agree that lying is always morally wrong. No one would want to be manipulated by deception into doing something.
Which of the following observations, if true, poses the most serious difficulty for the philosophy student’s argument?
A There are ways of manipulating people without lying.
B Many people would prefer to be lied to rather than have their feeling hurt.
C A claim is not a lie if the speaker believes it to be true.
D Many people unconsciously engage in self-deception to avoid unpleasant truths.
E People can learn how to detect deception in others.


Many in the medical profession are concerned that the widespread use of growth-promoting antibiotics in animal feed is reducing the antibiotics’ effectiveness in humans, because microbes can develop resistance to the drugs. Now MagnaBurger, a large fast-food chain, is considering agreeing not to buy meat from producers that use antibiotics as growth promoters. Such an agreement would certainly induce many producers to stop the use of antibiotics as growth promoters. Thus, if MagnaBurger decides to do this, it will probably reduce significantly the extent to which antibiotics are used as growth promoters.
Which of the following would, if true, most strengthen the argument above?
(A) It is considerably more expensive to raise animals without using growth-promoting antibiotics.
(B) Some countries have banned the general use of antibiotics in animal feed.
(C) If MagnaBurger stops buying meat from producers that use antibiotics that use antibiotics as growth promoters, other large fast-food chains are likely to do so, too.
(D) If MagnaBurger is the only fast-food chain that stops buying meat antibiotics, the prices that its competitors pay to purchase meat will decline.
(E) One study showed that there would be a dramatic drop in the incidence of antibiotic-resistant bacteria if antibiotics were no longer used as growth promoters in agriculture.
