which of the following lines from the speech supports the idea that roosevelt thinks truthful investigative journalism is a necessity?

a. "there should be relentless exposure of and attack upon every evil man whether politician or business man, every evil practice, whether in politics, in business, or in social life."

b. "there results a general attitude either of cynical belief in and indifference to public corruption or else of a distrustful inability to discriminate between the good and the bad."

c. "the fool who has not sense to discriminate between what is good and what is bad is well-nigh as dangerous as the man who does discriminate and yet chooses the bad."

d. "such laughter is worse than the crackling of thorns under a pot, for it denotes not merely the vacant mind, but the heart in which high emotions have been choked before they could grow to fruition."
