Question

1. which sentence best shows that the narrator is unreliable?

a \i lay back in my chair gasping with horror. my wife and family regarded me in wonder.\
b \knowledge like this was too much for the ordinary run - of - the - mill person.\
c \obviously they were simple beings, uni - cellular, some sort of primitive single - celled things.\
d \i need not, and came to this incredible revelation, tossed off coolly by the author without the faintest tremor\

Explanation:

An unreliable narrator is one whose credibility is questionable. Option D shows the narrator reacting to an "incredible revelation" with a calmness ("tossed off coolly") that is unexpected, which makes the narrator's account seem untrustworthy. Options A, B, and C do not show such a disconnect between the event and the narrator's reaction that would indicate unreliability.

Answer:

D. "I reeled on. And came to this incredible revelation, tossed off coolly by the author without the faintest tremor."
