I understood C to mean that "Many people moving into Weston failed to notify either the post office or the driver's license bureau that they had moved to the city" it would strengthen the conclusion because we now have even more reason to assume that reported population number would be low. As in, the real count of people moving into Weston is lower than what could/can be reported in the census. Was it silly to interpret it that way? What should I have caught in the stimulus or answer choice that would not led me go down that road of thinking?

if i can narrow down an RRE question to two answer choices, what's a good question/statement/phrase I can think of in the moment to ground me and remind me what i'm really looking for?
