Critical Reasoning (CR) | Re: County building inspectors report that almost fifty percent

More homes are now monitored for poisonous carbon monoxide fumes - (25% to 50%)

Total number of homes with confirmed dangerous fume levels is no higher now than it was fifteen years ago (2 Homes)
25% Homes - 2 Homes
50% Homes - 2 Homes

---> So % of Homes of with malfunctioning equipment must have increased for the conclusion - the same number of homes that breach level.
