Investing in real estate would be a profitable venture at this time. A survey in House magazine revealed that 85% of the magazine's readers are planning to buy a second home over the next few years. A study of the real estate industry, however, revealed that the current supply of homes could only provide for 65% of that demand each year.
Which of the following, if true, reveals a weakness in the evidence cited above?
Premise: 85% of magazine readers want to buy houses
Premise: 65% of those are satisfied.
Conclusion: real estate is profitable (why? because demand is greater than supply)
Possible weaken choice: when we see percentage, we should be cautious and think whether it could be translated into numbers. In addition, since the percentage here seems to describe surveyed people. We can think of: whether samples were biased, whether questions were biased (not shown here), whether the responses were biased (not shown here).
(If you couldn't think of the above, it's ok. Look at my explanations below)(A) Real estate is a highly labor-intensive business.
labor intensive doesn't have anything to do with the "profit" side of real estate in this problem.
Someone might think that labor intensive might mean higher wages, etc. But it is possible that we have the same number of people with the same wages (ps: happens a lot in developing counties where people were exploited by capitalism). Therefore, labor-intensive is unable to prove that real estate is not profitable.(B) Home builders are not evenly distributed across the country.
Whether home builders are evenly distributed have nothing to do with profitability. Unless the choice says, home builders are not evenly distributed which somehow make real estate not profitable etc. (C) The number of people who want second homes has been increasing each year for the past ten years.
Increasing number of people only make this industry more opportunities/clients -> more lucrative. Strengthen the conclusion.(D) Readers of House magazine are more likely than most people to want second homes.
I haven't seen any good explanations for this choice under this problem. Here is my try:
85% of the magazines readers. The people who conduct the research automatically apply this percentage 85% to the broader groups / entire society. And that 65% is obtained by real research. Ehh that sounds horrible. For example: let's say an entire society have 100 people. The magazine surveyed 20 ppl and 85% of them (17 ppl) want to buy a house. Then the magazine simply apply this 85% to that 100 people society. At the same time, there is a research saying currently there are 65 people being fulfilled. Note: 17 vs. 65. Not very profitable!
I seriously doubt that I made myself clear... But srsly, by looking at other answer choices, this is the only one that make a little tiny sense. But any opinions and discussions are welcomed!(E) House magazine includes articles about owning a second home as well as articles about building a second home.
Isn't that what a typical house magazine includes? I don't know why so many people chose E, but I thought what E can do is this: by including so many things about second house, increase someone's desire to buy a house. Therefore, the survey is biased because most of these ppl now want to buy a second house after reading all those articles! But isn't that what D is saying? D is much clearer. _________________
