Summarize Argument
The agricultural economist claims a worldwide grain shortage is likely. Why is it likely? Increases in grain production have nearly ceased. Additional increases would be difficult because most available farmland is being used at its maximum. While production is stagnant, demand is increasing because of continuous population growth.
Identify Argument Part
The stimulus text refers to a sub-conclusion. The claim that further increases would be difficult is supported with the evidence that farmland is already being used at near-maximum. This stimulus text gives evidence for the conclusion that a grain shortage is likely - thereby giving and receiving support within the argument.

Which one of the following ████ ██████████ █████████ ███ ████ ██████ ██ ███ ████████████ ███████████ ████████ ██ ███ █████ ████ ███████ █████████ ██ █████████ █████ ██████████ ████ ██ █████████ ██████████
a
It is one ██ ███ ███ ███████████ █████ ██ ███ ████████████ ██████████ ███████ ██ █████ ██ ████ ██ ███████ ███████ ███ ███ ██████
The stimulus text does support the ultimate conclusion. Difficulty increasing grain production is a reason to believe there will likely be a grain shortage.
b
It is a ███████████ ██ █ ███████████ █ ██████ ███████████ ██ █████ ██ ███ ████ ██████████ ██ ███ █████████
The conclusion does not explain why it is difficult to increase grain production. The phenomenon is instead used as support for the conclusion.
c
It is the ████ ███████ ███████ ██ ███████ ██ ███ ██████████ ████ ███████████
While it does support the conclusion, the stimulus text is not the only premise. Increased demand for grain and previous cessation of grain production increases also support the conclusion.
d
It is a ██████████ ███ █████ ███ ████████████ ███████████ █████ █████ ██ ███████ ██ ███ ███████ ██████████████
The first claim is not used to support that increased production will be difficult. The first claim is a separate idea about what has happened in the past.
e
It is an ████████████ ██████████ ████ ██ █████████ ██ ████████ ███ ███ ██████████ ████ ███████████
This accurately addresses how this statement both gives and receives support in the argument. The claim supports the conclusion that a grain shortage is likely, and the already near-maximal efficiency supports the claim.
