GMAT Critical Reasoning (CR) | Re: Compared to us, people who lived a century ago had very few diversions

Main argument is that: people in past likely read much more Because they had very few diversions to amuse them in comparison to today.

A - eliminated because argument doesn't mention anything about quality of books effecting the reading.

C - just because more books are sold today, doesn't mean that people today read more. Population today is much more than it was 100 years ago, so this point is refuted.

D - eliminated because the author doesn't mention 'cost of reading' being a valid cause.
