<span>It is false that comic relief is only found in comedies. Comic relief refers to funny sentences or events in an overall serious or dramatic play/novel so as to lighten up the mood. This type of technique is usually used in tragedies, quite ironically, even though people often think that comedies have more of it. Hope this helps.

The author introduced a clause within the sentence explaining how ‘air conditioning has taken root among big corporations’ was at first introduced by a DASH, but then later concluded with a comma. In order to make this consistent, one must do either of the following:
1. ...air conditioning—which is blah blah blah....powerful corporations—uses the simple power of ice. (replace comma with dash at the end)
OR
2. ...air conditioning, which is blah blah blah....powerful corporations, uses the simple power of ice. (replace dash with comma at the beginning)
Basically, when introducing a clause when breaking a sentence, either use 2 commas or a dash. dont use a mix of both. Hope this helped!
