A. Building a two-flat apartment requires far more time and effort than building a single-family residential home.
REJECTED - The time it takes in no way has a bearing on how long these flats stand without repair.
B. Two-flat apartments built prior to 1950 are much more commonly renovated than those built after 1950.
RIGHT ANSWER - If the Architects had been right, then there would have been n reason to renovate flats built before 1950. BUt as that is not the case, the architects' reasoning is not right.
C. Building materials used in two-flat apartments prior to 1950 were not much different than those used today.
REJECTED - In that case, then the quality of the construction was better before 1950 - strengthening the Architects' reasoning.
D. Today, the average two-flat apartment can be constructed in one-third the time it took to build a two-flat apartment prior to 1950.
REJECTED - This could mean that Construction techniques have improved after 1950, but in no way counters the architects' easoning.
E. It is extremely time intensive and expensive to renovate a two-flat apartment in compliance with city code.
REJECTED - That means, if there is a need ot renovate these flats, but people are hesitating ot renovate, then it is not because of the long-lasting and high-quality construction, bt because of the difficulty to adhere to the City code.
