(D) says, "The average ostrich farm generates almost five times as 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 out.
(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 stimulus.
Does this make sense? Let us know if you have any other questions!

What about food or facilities? I feel as though there is no way of knowing all the eternal factors...
