Dairy farmer: On our farm, we have great concern for our cows' environmental conditions. ██ ████ ████████ ████ ████████████ ████ ████████ █████ ████████ ████ ██ █████████ ████ ████ ███████ ████████ ███████████ █████ ███████ ███ ████████ ██ ████████ █████ ████ ██ ███ ██████ ████ █████████ █████ ████ █████ █████ ████ ██████ ███ ████ ████████ ████████
Summary
A dairy farmer explains that his farm is very concerned about its cows’ environmental conditions. To this end, it recently made improvements that increase the cows’ comfort, such as special mattresses that increase blood flow to the udder. The increased blood flow boosts milk output and raises profits.
Strongly Supported Conclusions
This practice (increasing blood flow to the udder) can also improve the cow’s environmental conditions.

Of the following propositions, which ███ ██ ████ ███████████ ██ ███ █████ ████████ ███████████
a
Dairy cows cannot ████ ███████████ ██████ ██████████ ██████ ███████ ████ ████ █████████ █████ ███ ██████████ ██ ████ ███████████
There are no conditions in the stimulus that dictate whether a cow can have comfortable living conditions (much less one that involves knowing the physiology of milk production).
b
Farming practices introduced ███ ███ ████ ██ ██████████ ███████ ███ ███████ ███ ██████ ██████████ ██ ████ ████████
The practice “introduced for the sake of maximizing profits” (special mattresses that increase blood flow) is said to increase the cows' comfort. Thus, this answer choice is supported.
c
More than other ████ ████████ █████ ████ ███████ █████████ ██ ████████████ ██ █████ ██████ █████████████
This has no support and is very difficult to support. The stimulus does not give any information about how cows respond to improvements in living environments, and there is no evidence that they respond more favorably than other farm animals.
d
The productivity of █████ █████ ██████ ██ █████████ ████ ██ ███ ███████ ██ ███ ███████ ██ ███ ████████████
The stimulus does not give any conditions about whether the productivity of a dairy farm should be increased. There is also no mention of the quality of the product.
e
The key to ██████████ ███████ ██ █ █████ ████ ██ ██████ █ ███████ ███ █████ █████ ████████████
The stimulus only says that the farmer is very concerned about the cows’ conditions and that a change to improve these conditions also led to increased profits. There is no evidence that the key to maximizing profits is to have a concern for cows’ environment.
