Answer:
Some the Louisiana Purchase was the best thing Jefferson ever accomplished because of the sheer amount of land the U.S gained for such an infinitesimal price in comparison.
Explanation:
(I'm not sure of the answer choices, but I can still try to help.)
The Louisiana Purchase is an infamous deal made by Thomas Jefferson that doubled the size of the United States. Part, if not all, of some states were founded from this decision. The people that believe the Louisiana Purchase was so great was because doubling the country by buying land for only three cents per acre was one of the greatest deals in history.
Therefore, the immense amount of land gained for such a small price (in comparison), is the reason some believed that the Louisiana Purchase was the best thing Jefferson ever accomplished.
You can also check the first sentence of the paragraph you inserted, which sums up what I just explained. The sentence reads: "Some say that this real estate deal was the best thing Jefferson ever accomplished because it doubled the size of the country and secured ownership of New Orleans."
