Meat from chickens contaminated with salmonella bacteria can cause serious food poisoning. Capsaicin, the chemical that gives chili peppers their hot flavor, has antibacterial properties. Chickens do not have taste receptors for capsaicin and will readily eat feed laced with capsaicin. When chickens were fed such feed and then exposed to salmonella bacteria, relatively few of them became contaminated with salmonella.

In deciding whether the feed would be useful in raising salmonella-free chicken for retail sale, it would be most helpful to determine which of the following?

(A) Whether feeding capsaicin to chickens affects the taste of their meat
(B) Whether eating capsaicin reduces the risk of salmonella poisoning for humans
(C) Whether chicken is more prone to salmonella contamination than other kinds of meat
(D) Whether appropriate cooking of chicken contaminated with salmonella can always prevent food poisoning
(E) Whether capsaicin can be obtained only from chili peppers

hi,
the Q has already taken that these are salmonella free chickens, so Choice B doesn't help us at all..

Now given that the chickens are salmonella-free chicken and so they have been eating CAPSAICIN, and also the retail sale is to be increased..

Retail sale would depend on Hygiene, cost and taste..
In A, we are given about taste so its OK..

May be a CHOICE talking of increase in PRICE due to use of a particular diet-- couold be also a reason if a part of choices..

I understood option B as if chicken eats capsaicin and this reduces the salmonella effect on humans, this can be used as a marketing strategy and be marketed aggressively and more people will buy these chicken. Where am I going wrong?
The passage doesnot mention about taste of chicken at all. If taste is good and food is still poisonous, people would not buy it right?

The option B talks about humasn eating the capsaicin not the chickens.

Option A talks about the things that can alter the buying trend.
Hence if the chicken still tastes good, people will buy it.

The key portion - whether the feed would be useful in raising salmonella-free chicken for retail sale


If it alters the taste then it would not be suitable for retail sale since the sales could be less.

I feel for option B but the above explainantion helps. The argument already states that if capsaicin is fed to chickens the probability of they being infected is low.

The question is a tricky one as the word RETAIL is mentioned towards the end.
A correctly mentions that if taste of the chicken after feeding capsaicin to them changes it may affect the RETAIL sale.

Its always easier to solve CR questions when you figure out what exactly is the argument saying.

Look at the question stem - "In deciding whether the feed would be useful in raising salmonella-free chicken for retail sale"
The argument's conclusion then would be - useful in raising salmonella-free chicken for retail sale.

Then I can write the argument as -
chicken feed laced with capsaicin --> useful in raising salmonella free chicken for retail sale.

Another thing to note is that "Evaluate" questions are hybrids; i.e. they are combination of strengthen and weaken questions. Supplying a yes/no answer to the correct answer choice must weaken/strengthen the conclusion OR strengthen/weaken the conclusion. (supplying yes/no must yield opposite results).
Let us look at the answer choices -
A - correct answer. Supply a "yes" to the answer option. If the taste of chicken sold is changed, then such meat might not sell well. Weakens the argument. Supply a "no". the meat tastes exactly the same - Strengthens the argument (Sales will not be affected).
B - look the argument written above again. We are evaluating the impact of chicken feed laced with capsaicin on retail sales. The impact of eating capsaicin on humans is irrelevant then.
Let us also try to supply a yes/no the answer option.
"No" - eating capsaicin does not reduce risk of salmonella in humans. We can say that this slightly strengthens the argument. The "yes" must now weaken the argument.

"Yes" - eating capsaicin reduces risk of salmonella in humans. Does not have any effect on the argument about the usefulness of feeding capsaicin to chickens.
Also, note that since capsaicin has a very hot flavor, this strategy might not work after all.(hence, does not weaken the argument). Another thing - which is easier? consuming capsaicin or feeding it to chickens? If feeding it to chickens is easier than consuming capsaicin, this option does not weaken the argument all.
C - Look at the argument written above. It is concerned only with "chicken meat"; other kinds of meat are not relevant.
D - Supply a "yes" and "no" to this option.
"No" - appropriate cooking can sometimes prevent food poisoning. Slightly strengthens.
"Yes" - appropriate cooking always prevents food poisoning. Does not mean that such chicken meat would not sell well. What if many people do not eat cooked meat? What if feeding capsaicin is the easier and cheaper way to go? What if cooking does not eliminate other harmful effects of salmonella but only eliminates food poisoning? Does not weaken.
E - Not relevant to the argument above. The method of obtaining capsaicin is irrelevant. Unless we know that other methods are substantially more expensive than obtaining capsaicin from chilly peppers.(in which case the price of such meat might be unreasonably expensive). Since, this option requires this additional assumption, it is incorrect.

In deciding whether the feed would be useful in raising salmonella-free chicken for retail sale, it would be most helpful to determine which of the following?
(A) Whether feeding capsaicin to chickens affects the taste of their meat: YES - Would you buy chicken that tasted different from the chicken you are used to eating?
(B) Whether eating capsaicin reduces the risk of salmonella poisoning for humans: No relation of humans and salmonella poisoning given
(C) Whether chicken is more prone to salmonella contamination than other kinds of meat: Not concerned about other meats.
(D) Whether appropriate cooking of chicken contaminated with salmonella can always prevent food poisoning: Questions asks about feed laced with capsaicin. We are not concerned about
(E) Whether capsaicin can be obtained only from chili peppers: NO JUST NO!

evaluate question: the answer choice strenghtens claim and weakens if negated
we are looking for an answer choice that would either support or weaken the Q that capsaicin will be useful for raising salmonella-free chickens for retail sales
A fits perfectly
the other are irrelevant

(E) Whether capsaicin can be obtained only from chili peppers

Since the chicken is already salmonella free, Option B,C,D and E are out of the scope. we are only left with A

The correct choice is A - Chickens will readily eat feed laced with capsaicin, which appears to protect them from contamination with salmonella bacteria that can cause food poisoning.

(A) Whether feeding capsaicin to chickens affects the taste of their meat Since we are concerned about how salmonella-free chicken would fare in retail sale, it would be useful to know whether capsaicin affects the taste of the meat.
(B) Whether eating capsaicin reduces the risk of salmonella poisoning for humans out of scope. Not told whether capsaicin affects humans.
(C) Whether chicken is more prone to salmonella contamination than other kinds of meat Not concerned with other kinds of meat
(D) Whether appropriate cooking of chicken contaminated with salmonella can always prevent food poisoning Again, not concerned how cooking impacts food poisoning.
(E) Whether capsaicin can be obtained only from chili peppers Irrelevant. Not concerned about the source of capsaicin.
