Microbiologist: A lethal strain of salmonella recently showed up in a European country, causing an outbreak of illness that killed two people and infected twenty-seven others. Investigators blame the severity of the outbreak on the overuse of antibiotics, since the salmonella bacteria tested were shown to be drug-resistant. But this is unlikely because patients in the country where the outbreak occurred cannot obtain antibiotics to treat illness without a prescription, and the country’s doctors prescribe antibiotics less readily than do doctors in any other European country.

Which of the following, if true, would most weaken the microbiologist’s reasoning?

A. Physicians in the country where the outbreak occurred have become hesitant to prescribe antibiotics since they are frequently in short supply.
B. People in the country where the outbreak occurred often consume foods produced from animals that eat antibiotics-laden livestock feed.
C. Use of antibiotics in two countries that neighbor the country where the outbreak occurred has risen over the past decade.
D. Drug-resistant strains of salmonella have not been found in countries in which antibiotics are not generally available.
E. Salmonella has been shown to spread easily along the distribution chains of certain vegetables, such as raw tomatoes.

Premise -
1. Microbiologist: A lethal strain of salmonella recently showed up in a European country, causing an outbreak of illness that killed two people and infected twenty-seven others. 2. Investigators blame the severity of the outbreak on the overuse of antibiotics, since the salmonella bacteria tested were shown to be drug-resistant.

Conclusion - But this is unlikely because patients in the country where the outbreak occurred cannot obtain antibiotics to treat illness without a prescription, and the country’s doctors prescribe antibiotics less readily than do doctors in any other European country.

Question Type - weaken, New information can be added to the answers.
Prephase - Investigators blame the severity of the outbreak on the overuse of antibiotics, but patients cannot obtain antibiotics to treat illness without a prescription
Alternate source of Antibiotics injected.
Practitioners prescribing antibiotics for other diseases.
Extreme prephase - Flaw in Microbiologist/ Investigators results.

A. Physicians in the country where the outbreak occurred have become hesitant to prescribe antibiotics since they are frequently in short supply. - Irrelevant.
B. People in the country where the outbreak occurred often consume foods produced from animals that eat antibiotics-laden livestock feed. - Pre-thought ans - Alternate source of antibiotics.
C. Use of antibiotics in two countries that neighbor the country where the outbreak occurred has risen over the past decade. - Doesn't impact the conclusion, as stated the practitioners govern the use of the antibiotics.
D. Drug-resistant strains of salmonella have not been found in countries in which antibiotics are not generally available. - This statement can act as a premise, as it states what already is given in the argument.
E. Salmonella has been shown to spread easily along the distribution chains of certain vegetables, such as raw tomatoes. - Contender,but does not relate the patients to Salmonella

OG Verbal 2017 New Question(Book Question: 172)


Microbiologist says that antibiotics is not the reason for Salmonella infection. Our job is to find that Antibiotics are the reason.

A. Physicians in the country where the outbreak occurred have become hesitant to prescribe antibiotics since they are frequently in short supply. We want to know the status of Antibiotics use before infection took place.

B. People in the country where the outbreak occurred often consume foods produced from animals that eat antibiotics-laden livestock feed. Correct choice. Animals are given antibiotics, and since these animals are eaten by people in the country, people are indirectly consuming antibiotics.

C. Use of antibiotics in two countries that neighbor the country where the outbreak occurred has risen over the past decade. We are not concerned about antibiotics use in neighboring countries.

D. Drug-resistant strains of salmonella have not been found in countries in which antibiotics are not generally available. We want to know if infection happened because of antibiotic resistance.

E. Salmonella has been shown to spread easily along the distribution chains of certain vegetables, such as raw tomatoes. We want to know if infection happened because of antibiotic resistance.

I think E weakens the conclusion whereas B weakeans the reasoning.

E mentions a source of antibiotics but never mentions that people are actually consuming that source (tomatoes).

But option B clearly mentions that people are consuming meat which is a good source of antibiotics.

Therefore I suppose that B is a better option.

But this is unlikely because patients in the country where the outbreak occurred cannot obtain antibiotics to treat illness without a prescription, and the country’s doctors prescribe antibiotics less readily than do doctors in any other European country.

Which of the following, if true, would most weaken the microbiologist’s reasoning?

A. Physicians in the country where the outbreak occurred have become hesitant to prescribe antibiotics since they are frequently in short supply.
(Out of Scope)
B. People in the country where the outbreak occurred often consume foods produced from animals that eat antibiotics-laden livestock feed.-Correct Answer since this choice describes the source of the antiboitics and negates the conclusion
C. Use of antibiotics in two countries that neighbor the country where the outbreak occurred has risen over the past decade.
(Out of Scope )
D. Drug-resistant strains of salmonella have not been found in countries in which antibiotics are not generally available.
(does not weaken)
E. Salmonella has been shown to spread easily along the distribution chains of certain vegetables, such as raw tomatoes.
(out of Scope also it strengthens the argument.)

Situation: Antibiotic-resistant salmonella caused an outbreak of illness in a European country where patients need prescriptions to obtain antibiotics and where doctors dispense such prescriptions less readily than in other European countries

Reasoning: What evidence would most strongly suggest that overuse of antibiotics was likely responsible for the outbreak, despite the cited facts?

B is correct - Weakens the microbiologist's argument by indicating that an assumption implicit in the argument may be false: the salmonella outbreak could easily by explained by overuse of antibiotics in livestock feed (perhaps imported from other countries).

Microbiologist: A lethal strain of salmonella recently showed up in a European country, causing an outbreak of illness that killed two people and infected twenty-seven others. Investigators blame the severity of the outbreak on the overuse of antibiotics, since the salmonella bacteria tested were shown to be drug-resistant. But this is unlikely because patients in the country where the outbreak occurred cannot obtain antibiotics to treat illness without a prescription, and the country’s doctors prescribe antibiotics less readily than do doctors in any other European country.

Which of the following, if true, would most weaken the microbiologist’s reasoning?

A. Physicians in the country where the outbreak occurred have become hesitant to prescribe antibiotics since they are frequently in short supply.
- OPPOSITE. if physicians hesitate to prescribe antibiotics, then it strengthens the idea antibiotics could not have increased severity of the outbreak

B. People in the country where the outbreak occurred often consume foods produced from animals that eat antibiotics-laden livestock feed.
- Breaks the idea that the outbreak was not strongly influenced by antibiotics. in fact, tells us people found other ways of consuming antibiotics (this way, in what they ate)

C. Use of antibiotics in two countries that neighbor the country where the outbreak occurred has risen over the past decade.
- irrelevant. who cares about other neighboring countries? we don't know how they're related -- they could be totally different

D. Drug-resistant strains of salmonella have not been found in countries in which antibiotics are not generally available.
- irrelevant & extreme language "not generally available". that's not said here, what is said is that doctors prescribe antibiotics less readily than in other countries. this could still be a high #

E. Salmonella has been shown to spread easily along the distribution chains of certain vegetables, such as raw tomatoes.
- irrelevant. who cares if it spreads easily and/or how it spreads?

Kudos please if helpful :)
