Self-study
Antibiotics are standard ingredients in animal feed because they keep animals healthy and increase meat yields. ████████ ██████████ ████ ███████████ ███████ ███ ████ █████████ █████████ ██ ███ ████ ███████████ ████ █████████ ██ ███████ ██ ████ ██████ ███ ████████ ████████ ████ ███████ ████ ██ ███ ██ █████████
Summary
Antibiotics in animal feed keep animals healthy and increase meat yields. However, scientists recommend reducing antibiotics in animal feed because this practice may cause antibiotics to be less effective for humans. If meat yields are reduced, some farmers will go out of business.
Strongly Supported Conclusions
If antibiotics in animal feed are removed without another way to increase meat yields, then some farmers will go out of business.

Which one of the following ██ ████ ████████ █████████ ██ ███ ███████████ ██████
a
If scientists are ███████ ████ ██████████ ███ ██ ██████ ████ █████ ███████████ ████ █████████ ██ ███████ ████ ████ ███████ ████ ██ ███ ██ █████████
This answer is unsupported. We don’t have any condition that would be triggered if the scientists are correct. The scientists could be correct without any action being taken.
b
If antibiotic use ██ ██████ ████ ██ ███ ██████ ████ ████ ███████████ ████ ██████ ███████████ ██ ███████
This answer is unsupported. First, the stimulus doesn't actually state that the scientists are correct. Second, even if it did, saying the antibiotics would become “ineffective” is too strong.
c
If the scientists' ██████████████ ██ ███ ███████ ██ ███████ ████ ██ ███ ██ ████████ ███ ██ ███████ ████ ███████
This answer is unsupported. There could be other factors that cause reduced meat yields and lead to farmers going out of business.
d
If the health ██ █████ ███████ █████████ ████ ███████ ████ ███ ██ ████ ██ ████ ██ █████████
This answer is unsupported. The stimulus doesn't tell us any direct effects of animals becoming less healthy. And even if we assume that it would reduce meat yields, we can't say that "most" farmers would go out of business.
e
If antibiotic use ██ ██████ ████ ██ ██████ ████ ████ ███████ ████ ██ ███ ██ ████████ ██████ ████ ███ █████ █████ ██ ██████████ ████ ███████
This answer is strongly supported. Antibiotics currently help to keep meat yields high, and reduced yields is sufficient for some farmers to go out of business. So, unless there’s another way of increasing meat yields, some farmers will go out of business if antibiotics are phased out.
