The conclusion of the real estate agent's argument is the following:
a real estate agent familiar with a home and its neighborhood can assess the home's true market value far more accurately than any automated Web site canThe support for that conclusion is the following:
Unlike the Web sites, a real estate agent can take into account a home's intangible aesthetic factors, such as views and interior design.The correct answer must strengthen the support for the conclusion.
A. In general, real estate agents who take into account intangible aesthetic factors assess homes' market values far more accurately than other real estate agents do.This choice strengthens the argument by indicating that taking into account intangible aesthetic factors does result in a more accurate assessment of a home's value.
After all, the fact that "real estate agents who take into account intangible aesthetic factors assess homes' market values far more accurately than other real estate agents do," allows for a comparison of the what occurs when taking into account intangible aesthetic factors is involved in assessments and what occurs when it is not involved.
We see that assessments that DO involve taking into account intangible aesthetic factors are more accurate than similar assessment that DO NOT involve taking into account intangible aesthetic factors.
Thus, this choice provides additional reason to believe that "a real estate agent familiar with a home and its neighborhood can assess the home's true market value far more accurately than any automated Web site can" by indicating that the real estate agent's taking into account intangible aesthetic factors will indeed result in an assessment more accurate than one made by a web site that does not take into account such factors.
Keep.
B. Most real estate agents take into account at least some intangible aesthetic factors when assessing a home's market value.Notice that the conclusion of the argument is that "a real estate agent ... CAN assess the home's true market value far more accurately." The conclusion is not that all real estate agents DO assess homes' true market values far more accurately than web sites.
Also, the support for that conclusion is that "a real estate agent CAN take into account a home's intangible aesthetic factors."
So, the reasoning is about what CAN occur because of what a real estate agent CAN do.
Now, notice that the fact stated by this choice "most real estate agents take into account at least some intangible aesthetic factors" does not mean that, as a result "a real estate agent ... can assess the home's true market value far more accurately." In other words, the fact that real estate agents take into account intangible factors doesn't mean that taking those factors into account makes any difference.
Regardless of what most real estate agents do, taking those factors into account may not make any difference.
So, this choice has no effect on the argument.
Eliminate.
C. By considering a home's own sales history, a Web site can automatically account for many intangible factors specific to that home.If anything, this choice weakens, rather than strengthens, the argument by showing that, even though a web site may not be able to directly evaluate intangible aesthetic factors, an assessment by a web site may still indirectly take into account such factors and thus may not be as different from one made by an agent as the argument supposes.
Eliminate.
D. It is in a home seller's financial interest to have a real estate agent assess the home's market value as accurately as possible.The fact stated by this choice doesn't indicate anything about how accurately a real estate agent can assess a home's market value. After all, what's in a home seller's interest and what a real estate agent can do are two different things.
Eliminate.
E. The recent sales prices of other homes in a neighborhood reflect intangible aesthetic factors that affect the desirability of the neighborhood as a whole.This choice tempts us to choose it by mentioning "aesthetic factors" and thus seeming to be relevant to the argument.
At the same time, this choice certainly doesn't support the conclusion that "a real estate agent ... can assess the home's true market value far more accurately than any automated Web site can."
After all, we know from the passage that web sites do use "recent sales prices of other homes in a neighborhood" in assessing the values of homes. So, this choice indicates that web sites can take into account at least some intangible aesthetic factors, which indicates that real estate agents may have less of an advantage than the argument supposes they have.
Eliminate.
