LR Question 7 Explanation, by LSATHacks

QUESTION TEXT: Antibiotics are standard ingredients in animal feed…

QUESTION TYPE: Most Strongly Supported

FACTS:

1. Antibiotics keep animals healthy and improve meat production.
2. Scientists recommend stopping the use of antibiotics. This practice may decrease the effectiveness of antibiotics in humans.
3. If animals produce less meat, then some farmers will go out of business.

ANALYSIS: We know that antibiotics help yields, and that if yields go down, some farmers will go out of business.

We don’t know that antibiotics will be banned. Society might not listen to scientists.

But if we do listen to scientists, some farmers will go out of business.

___________

1. This is only true if we take scientists’ advice and stop giving antibiotics to animals. We don’t do everything scientists say.
2. The stimulus is vague on this point. Antibiotic use in animals may make antibiotics less effective. They might still work to a lesser degree.
3. Meat yields might drop for some other reason. Plague of locusts, perhaps?
4. Close, but we don’t know exactly how antibiotics increase meat yields. It might not be because they increase animals’ health.
5. CORRECT. This has to be true. Meat yields will drop if antibiotic use is phased out, unless farmers find some other way of keeping yields up.
