GMAT Critical Reasoning (CR) | Re: There are more opera houses than there were two decades ago,

"D talks about "emphasis on unamplified sound in opera". In this case, I have understood it to mean that because of this, the size of the opera houses has been decreasing. Now this would explain why the average audience has reduced (as capacity is less), while at the same time, because of more interest in opera, more people are contributing to it as charity in order to build more opera houses."
