why do people say "I could care less"? that implies that they still care when they are trying to say that they couldn't care less. WHO STARTED SAYING I COULD CARE LESS???

No one is certain when the phrase was coined.

Explanation:

Webster the Marriam version (citing Hearst’s International - Cosmopolitan) states that it's earliest use dates as far back as 1929.

It is interesting to note that "I could care less" and I couldn't care less" are used as synonyms to mean that one is not overly concerned about a matter.

An example would be:

Tired and worn out, he sat up. ”I couldn’t care less,” he said, “whether you stay or not.”

compare & contrast informative essay/speech

when speaking or writing for the sole purpose of providing information in order to give audience members a good basis for making a decision, you would present an informative speech or essay.   because you wouldn’t want to be persuading the audience by arguing for one type of exercise over the other, you wouldn’t choose a persuasive/argumentative technique.   to fairly, and without bias, present information about the pros and cons of each type exercise, a compare/contrast, informative speech/essay would be the best bet.

is it rising action, falling action, climax, or resolution? need answer also
