Answer choice?

@AnkitM let's take a closer look. We have an apparent discrepancy in the stimulus: (1) the TELEPHONE poll in the summer of 1936 predicted that Alfred Landon would soundly defeat Franklin Roosevelt. BUT (2) Roosevelt actually won the election in a landslide. This is a Paradox question asking us to find the answer choice that best explains why the poll's prediction was inaccurate. (C) is a possible explanation for this discrepancy. If phone ownership was less common in 1936 than it is today and only those who could afford telephones would be polled, it serves as a possible explanation as to why the poll's prediction was inaccurate. Remember, on Paradox questions, we are simply looking for a possible explanation for the discrepancy. (C) is clearly a possible explanation because it highlights the possibility that people who could not afford telephones in 1936 (and thereby were excluded from the telephone poll) supported Roosevelt. Hope this helps! Please let us know if you have any other questions.

But in answer choice B, couldn't you say that there were many more people who voted in the election, but merely were not yet registered to vote when the polling service was calling? So therefore explaining why the results might have been inaccurate?

@joryjes no, (B) is irrelevant. Read (B) carefully. "Only people who would be qualified to vote by election time were interviewed . . . " Unqualified voters would not be able to explain why the outcome was radically different than the poll's prediction. Hope that helps! Please let us know if you have any other questions.
