Quizplus · Accepted Answer

The sentence mentions doubts about the generalizability of results, which implies a need to replicate the experiment in more cities to ensure that the results are applicable to other populations. Option B correctly reflects this need for replication. Option A is incorrect because it is essentially repeating the same experiment in multiple cities, rather than replicating the results of the initial experiment. Option C is not mentioned in the sentence and is therefore irrelevant. Option D is also incorrect because the sentence does not mention measurement invalidity as a concern.
