The Ringmaster's Advice
People say, "any publicity is good publicity" allthe
time. It's become a modern truism. But people don't seem
to give much thought to where it came from.
While there is no proof that he used exactly those
words, the quote is widely attributed to showman P.T.
Barnum. I think it's safe to say that even if he never said
"any publicity is good publicity," it describes his lived
ethos.
P.T. Barnum was the founder of the Barnum &
Bailey Circus, billed as "The Greatest Show on Earth." He
advertised fake mermaids and a woman who claimed to
be George Washington's 161-year-old nurse. Barnum's
traveling shows featured midgets, Siamese twins, bearded
ladies, and even "Jo-Jo the Dog-Faced Boy."
There's no record of him saying these exact words
either, but he is also widely credited with the quote,
"there's a sucker born every minute."
P.T. Barnum did describe himself as the "Prince of
Humbug," proudly owning his reputation for hoaxes and
"harmless" deceptions.
Barnum was an interesting character, but he's not
a man we should be encouraging other men, especially
young men, to emulate. Unfortunately, his ethos is more
or less what social media has been teaching kids for the
past ten years.
And at the same time, everyone complains that
everything is "fake and ghey."
Well... if you follow the ringmaster's advice, don't
be surprised when you end up living in a circus.

Analyze the following statements regarding
the phrase the quote is widely attributed to showman
P.T. Barnum:
I. Using the passive voice puts Barnum at the center of the sentence, which fits the paragraph's focus on his reputation and legacy.
II. The point is that it is widely said Barnum is responsible for the quote. The passive voice elegantly generalizes and vagueness the source, which is appropriate for common attribution or collective opinion.
III. The writer wants the reader to pay attention to who receives the credit (P.T. Barnum), not who exactly is doing the crediting ("people say", "historians claim", "critics argue").
The CORRECT statements are:

in the phrase it describes his lived ethos,
