In the 18th and 19th centuries, it was believed in many coastal American cities that the waterfront was an undesirable location for residential buildings. As a result, much of the waterfront in these cities was never developed aesthetically and instead was left to industry and commerce. Today, however, waterfront properties are generally seen as prestigious, as evidenced by the large sums paid for homes along the beach front. A developer who wishes to make a large profit would be wise to buy urban waterfront lots and erect residential buildings on them.
Which of the following, if true, most strongly supports the claim made about urban waterfront properties?
A.People today have more money, relatively speaking, to spend on real estate than they did in previous centuries.
B. Homeowners will be willing to spend large sums on residential properties in traditionally industrial or commercial districts.
C. Many urban waterfront lots are available for purchase.
D. Many coastal American cities are encouraging developers to rehabilitate the waterfront through tax incentives.
E.Properties in interior residential districts in coastal American cities are significantly more expensive than those along the waterfront.
The question is from MANHATTAN GMAT CAT exam.
I chose C, Ans is B.
My reason is that C is the argument assumption: It Helps the argument in that okay, if you want profit by buying the land, at least you are able to buy the land. Therefore, C supports the argument.
In ManhattanGMAT CR: assumption helps to establish the feasibility of premise of the argument. Therefore, it strengthens the argument.
What is wrong with my logic?
(I suspect that the word "Many" in Choice C makes it wrong?)
Thank you.
PS: Might be this is my last post. I will have the exam in two days. Wish me good luck :v
