Because most agricultural practices in North America produce row after row of only a few, genetically identical, varieties of crops, the continent's food system rests precariously on a rapidly eroding genetic base, increasingly susceptible to pests and disease. ███

Purpose of passage
In a Problem-Analysis passage, if the author supports a solution to the problem, the primary purpose of the passage should relate to the author’s support for the solution. Here, the author’s primary purpose is to support research into indigenous knowledge of heirloom crops as a way to solve the problem of North American crops’ eroding genetic base.
a
criticize current efforts ██ █████ █ ███████
Although the author does have a slightly negative attitude toward research focused solely on methods brought from outside North America, the main purpose of the passage is broader than this criticism. The author focuses instead on supporting research into indigenous knowledge.
2%
b
contrast two approaches ██ ███████ █ ███████
This doesn’t capture the author’s support for research into indigenous knowledge. The author’s intention isn’t merely to describe differences between approaches; it’s to support a particular approach.
1%
c
propose a novel ████████ ██ █ ███████
Tempting, but not accurate, because the author doesn’t “propose” a “novel” (new) solution. Rather, the author identifies a potential solution that is being pursued by researchers and experts. The author isn’t the one who comes up with a new solution.
9%
d
praise a definitive ████████ ██ █ ███████
“Definitive” is too strong. The author never suggests that the solution is definitive or otherwise certain to work. Rather, the author uses the phrase “possible solution.”
5%
e
support a promising ████████ ██ █ ███████
This best captures the author’s purpose, which is to support research into indigenous knowledge of heirloom crops as a way to solve the problem of North American crops’ eroding genetic base.

Stems asking us to infer an idea implied by the claims in the passage (as opposed to identifying an idea that appears explicitly). Similar to most strongly supported questions in LR.
Stems that ask us to describe the overall purpose of the passage. Similar to main point questions, but often call for more abstract language in the answer choices (e.g. "to criticize a popular theory").
Passages that present a particular problem and then discuss the implications of that problem. They also often explore one or more solutions to that problem (although they don’t have to).
