much profit as the average cattle ranch."

We know that an ostrich farm can eventually bring in five times as
much as the cattle farm. However, we do not know what happens to the
average ostrich farm, so (D) isn't supported by the stimulus. It's

(A) says, "Two pairs of yearling ostriches are more expensive than a
herd of cows and a bull."

(A) has to be true. Initially, an ostrich farm costs more than a
cattle farm does. Ostrich farms need two ostriches. Cattle farms need
a big herd of cows and one bull. Given this, the two ostriches must
cost more than the cows and the bull cost. However, we know that
everything else isn't equal. Fewer acres are required for the
ostriches than for the cows, so this means that the two ostriches are
definitely more expensive than the cows are. Thus, (A) is the correct
answer, and it's the one that's most strongly supported by the
