Reading the passage
First state the relationship before looking for a similar pair. Ordinary crop cultivation couldn't readily support such a large, concentrated population in this environment. The cattle economy supplied the food system that made that population possible.
What we’re looking for
So we want something that enables an activity to exist where the natural conditions would otherwise prevent it. “Two things that are important” is too loose; we need the supporting relationship.
Working the answers
- A
Hunting and gathering are two ways of obtaining food. Hunting isn't presented as the support that makes gathering possible in an otherwise unsuitable environment. Sharing a subject doesn't make the relationship match.
- BCorrect
A desert farm needs a way to obtain water despite its dry setting. Irrigation supplies that support, just as the cattle economy supplied a way to sustain a large population despite the local limits on crop production. In each case, the first element makes the second possible under difficult environmental conditions.
- C
Accounting and marketing are different business functions. We aren't given a relationship in which accounting makes marketing possible despite an environmental obstacle.
- D
A stadium provides a venue for athletic contests, but contests can occur without a stadium. That doesn't match overcoming an environmental barrier to sustaining the population, as irrigation does for farming in a desert.
- E
Stones are components of a stone wall. The cattle economy isn't a collection of smaller pieces that make up the city's population; it's what helps sustain that population. A part-to-whole relationship is the wrong structure.
