In the case of Class B apartments, landlords are allowed to revise rental rates once every five years, from the time of entering into a rental agreement. The landlord can increase the rent by adding to the previous rent a percentage increase, determined by the rate of inflation and the change in local property prices over the previous five-year period.
Which of the following statements, if true, is the best basis for a criticism of the method of calculating allowed rent increases as an economically appropriate method?
A. Many people decry the increasing percentage of their income that people must spend on rent.
B. Over the past thirty years, the rate of inflation has varied significantly.
C. The rent will be greatly affected by the changes in the locality of the apartment.
D. Renters might continue to pay for unfair rental rates negotiated in the past.
E. The suggested method of calculating rent increases might not encourage landlords to maintain Class B apartments very well.
Experts' Global Explanation: Mind-map: Class B apartment landlords can revise rents every five years à rents can be increased by a percentage of previous rent à increase percentage determined by inflation and increase in property rates in locality à method of calculating allowed rent increases is economically appropriate (implicit conclusion)
Missing-link: Between all the information presented and the conclusion that the method of calculating allowed rent increases is economically appropriate
Expectation from the correct answer choice: To weaken the conclusion that the method of calculating allowed rent increases is economically appropriate
A. The argument is concerned with whether the suggested method of calculating allowed rent increases is economically appropriate; whether many people disapprove the increase thus calculated
provides no information about the economic appropriateness of the method; so, this answer choice is
just a general opinion and does not weaken the argument. Because this answer choice does not weaken the conclusion, this answer choice is incorrect.
B. Trap. The argument mentions that the new rental rates would be calculated by considering inflation; so, if inflation has varied considerably in the past, it
indicates that the increase in rental rates has varied; however,
varying increase in rental rates provides no information about the economic appropriateness of the suggested method; so, this answer choice is just additional detail and does not weaken the conclusion. Because this answer choice does not weaken the conclusion, this answer choice is incorrect.
C. Trap. The argument mentions that the
new rental rates would be calculated by considering the change in local property prices; so, this answer choice, suggesting the influence of the changes in the locality of the apartment,
adds no new information and does not weaken the argument. Because this answer choice does not weaken the conclusion, this answer choice is incorrect.
D.
Correct. The argument mentions that the new rental rates would be based on a percentage increase in previous rental rates; so, if the previous rental rates were poorly negotiated by renters, it indicates that the
unfair rates would continue in successive rental agreements as well; so, this answer choice, highlighting this possibility,
criticizes the suggested method on economic grounds, thus weakening the conclusion. Because this answer choice weakens the conclusion, this answer choice is correct.
E. Trap. The argument is concerned with whether the suggested method of calculating allowed rent increases is economically appropriate; how the landlords’ motivation to maintain apartments is impacted by the method
provides no information about the appropriateness of the method; so, this answer choice is just additional information and does not weaken the argument. Because this answer choice does not weaken the conclusion, this answer choice is incorrect.
D is the best choice.
