Since the routine use of antibiotics can give rise to resistant bacteria capable of surviving antibiotic environments, the presence of resistant bacteria in people could be due to the human use of prescription antibiotics. Some scientists, however, believe that most resistant bacteria in people derive from human consumption of bacterially infected meat.

Which of the following statements, if true, would most significantly strengthen the hypothesis of the scientists?

(A) Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals.

(B) Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics.

(C) The incidence of resistant bacteria in people has tended to be much higher in urban areas than in rural areas where meat is of comparable quality.

(D) People who have never taken prescription antibiotics are those least likely to develop resistant bacteria.

(E) Livestock producers claim that resistant bacteria in animals cannot be transmitted to people through infected meat.

If livestock are routinely fed antibiotics, as choice A states, meat from livestock is likely to contain the resistant bacteria, since any routine of antibiotics can result in resistance bacteria. Thus, choice A is the best answer.

How cases of food poisoning are treated (choice B) fails to indicate whether the infection bacteria are resistant bacteria. Choice C suggests that meat consumption is not the primary culprit for the high incidence of resistant bacteria. Choice D tends to support the competing hypothesis that prescription antibiotics are responsible. Choice E asserts that livestock farmers claim that the hypothesis is false, but it provides no basis for evaluating the truth of this claim.

A. SUFF. The first sentence talks about bacteria becoming resistant and if A is true, whatever bacteria left from the constant antibacterial injection should be very resistant.
B. This just talks about the "fix"
C. out of scope - quality doesn't equal bacterial infected
D. out of scope
E. weakens the hypothesis

Looks A to me .

Conclusion:Some scientists, however, believe that most resistant bacteria in people derive from human consumption of bacterially infected meat.

A) Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals. - satisfies this conclusion as well as premise

It looks like A.
Constant exposure to antibiotics causes Resistance in bacteria. If antibiotics are injected into all meat for consumption, then, if any meat is infected with bacteria, those bacteria will develop resistance to the antibiotics. On consumption of such infected meat, those resistant bacteria will be transmitted to humans. That makes sense.

According to B, antibiotic use by humans is still responsible for antibiotic resistance in humans. This weakens the scientists' hypothesis.

But in the end, are the antibiotics, not the meat the cause of bacteria resistance...

IMO , its A.
It gives a reason that because Antibiotics are present in the feed , it may lead to develop the resistant bacteria in the meat.

Read the question stem first. It is a strengthen question. Read the stimulus with focus on scientists' hypothesis.
It is the following: most resistant bacteria in people derive from human consumption of bacterially infected meat.
The stimulus also tells us that routine use of antibiotics create resistant bacteria.
Option (A) - Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals.
If livestock get antibiotics, then the livestock that was bacterially infected in the first place, perhaps harbor resistant bacteria. If people ate that infected meat, it is quite possible that they will harbor resistant bacteria too. This would strengthen the hypothesis that resistant bacteria in people derive from consumption of infected meat.

(B) Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics.
If people were prescribed antibiotics, they would develop resistant bacteria in their own bodies. So it doesn't strengthen the hypothesis that the resistant bacteria are transferred from consumption of meat.
(C) The incidence of resistant bacteria in people has tended to be much higher in urban areas than in rural areas where meat is of comparable quality.
Comparison of rural and urban areas is irrelevant.

(D) People who have never taken prescription antibiotics are those least likely to develop resistant bacteria.
It strengthens the other view "the presence of resistant bacteria in people could be due to the human use of prescription antibiotics." given in the stimulus, not the hypothesis of the scientists.

(E) Livestock producers claim that resistant bacteria in animals cannot be transmitted to people through infected meat.
The claim of producers holds no value. Even if it did, it would weaken the hypothesis of the scientists.

Which of the following statements, if true, would most significantly strengthen the hypothesis of the scientists?
(A) Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals.
-->Since antibiotics are fed to the livestock the animals may become resistant to the drugs. If humans eat the meat from these animals they too may become resistant. This strengthens the hypothesis.
(B) Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics.
-->We are not talking about food poisoning and the treatment of it. Eliminate.
(C) The incidence of resistant bacteria in people has tended to be much higher in urban areas than in rural areas where meat is of comparable quality.
-->Out of the scope of the argument. We are looking for something to strengthen why scientists believe most resistant bacteria comes from the consumption of bacterially infected meat.
(D) People who have never taken prescription antibiotics are those least likely to develop resistant bacteria.
-->This may be true but not what we are looking for. Eliminate.
(E) Livestock producers claim that resistant bacteria in animals cannot be transmitted to people through infected meat.
-->This statement weakens the argument.

I actually crossed them all out and had to go back and recheck to end up with A.
Conclusion: Scientist hypothesize that the most resistant bacteria come from the consumption of meat.

I feel like there should be an additional information in A: how do we know if the bacteria in meat actually transmits to humans? Are we assuming it as a common knowledge? Thank you

Scientists hypothesis: most resistant bacteria in people derive from human consumption of bacterially infected meat.

We need to STRENGTHEN!

(A) Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals
Antibiotics lead to resistant bacteria in meat so when these are consumed by humans they get it

C - out of scope, urban and rural meats are not compared.
E - Weakens the argument
B - talks about treatment but doesnt support the hypothesis
D - This is the opposite. It argues that antibiotics are the cause and not the meat.

You should think so much for the questions and then slowly slowly you will develop logic .
