Lining up what the narrators expected against what turned out to be true makes the theme obvious without needing to weigh all four options equally.
That mismatch between expectation and reality, built entirely on how the man looked, is a direct illustration of appearances being deceptive, not a comment on education, blind faith, or the reliability of stereotypes, none of which describe this specific expected-versus-actual gap.
Two words in the question matter a lot here, 'initial impression' and 'most strongly,' so the answer has to be the theme tied specifically to that first, appearance-based judgment, not to anything that happens afterward.
Anchoring the answer to that specific initial, appearance-based moment leaves only one option standing.
So the correct answer is The deceptive nature of appearances.
A fast check for hyperbole is to ask: could this statement be literally true? If the answer is an obvious no, and it is clearly said for effect, that points to hyperbole.
Since the line is an obvious, impossible-to-take-literally exaggeration used purely for effect, it is hyperbole.
Paying attention to the narrator's tone in this specific line helps rule out the close competitors, irony and allegory, before settling on the answer.
The admiring, over-the-top tone of the line points squarely at deliberate exaggeration rather than any of the other three devices.
So the correct answer is Hyperbole.
Theosophy is the actual name of a nineteenth-century spiritual movement that claimed access to hidden, esoteric knowledge about the universe through spiritual insight rather than ordinary observation. A 'theosophist' is simply a follower of that movement.
Knowing the actual movement behind the word makes 'mystic' the only option consistent with what a theosophist believes.
All four options describe different stances toward spiritual or occult claims, so sorting them along that single spectrum, from denial to belief, makes the answer clear.
A theosophist, by the passage's own description of someone touched by 'magnetism, occult power, or astral body,' belongs firmly at the belief end of that spectrum, which is the mystic.
So the correct answer is Mystic.
'Boorish' comes from 'boor,' an old word for a peasant or country farmer, and it came to describe someone with the rough, unrefined manners stereotypically associated with that word.
Tracing the word back to its root confirms that 'boorish' describes rude, ill-mannered behaviour, matching discourteous.
Every one of these four words carries a connotation, either negative or positive, and sorting them by that connotation alone answers the question quickly.
'Boorish' itself carries a negative connotation, describing crude, unpolished behaviour, so it can only match the one option that shares that negative charge, discourteous, and not the three positive ones.
So the correct answer is Discourteous.
Tracing the specific cause of the feeling makes this quick to answer.
Being pleased at being recorded only makes sense if he enjoys having an effect on his audience, being found impressive enough to write about. That rules out humility or embarrassment (negative feelings), avoiding recognition (which being noted down would work against), and indifference (which is not a feeling at all), leaving satisfaction at impressing and influencing others as the only fit.
This single moment fits a pattern that runs through the whole passage, so reading it alongside the man's other behaviour supports the same conclusion from a different angle.
Seen against the rest of his character in the passage, being quietly pleased fits a man who enjoys impressing and influencing the people around him.
So the correct answer is He derived satisfaction from impressing and influencing others.
