read the sentence from the passage.

he cannot stop with merely thinking a thing is so and so; he must know it; for this is one of the "exact" sciences.

how does the word "exact" affect the meaning of the sentence?

it shows that the narrator has a mistrust of science.

it suggests that the sentence should be taken literally.

it hints that the narrator's words are meant ironically.

it places emphasis on the precise nature of the science.

I'm going to say C.

Explanation:

This person cannot simply think a thing is so and so - he must KNOW it, which I assume means he would test it out for himself. The entire sentence indicates his mistrust of science. However, if we are just talking about the word "exact", it is in quotations and doesn't make sense with the rest of the sentence (if taken serious) so I think it is meant to be taken ironically.

the answer is a).

i go to the store and buy some cheese,suddenly there was akward silence.   out of no where comes a ninja, and he takes an apple, and chokes the cashier, until he passes out.   the disapeared in a puff of smoke.   the cashier went to the doctor, and everything was fine again.   they all lived happily ever after without anymore ninjas.

go to buy cheese= exposition

akaward silence= rising action

ninja chokes the cashier= climax

cashier goes to the doctor= falling action

they live happily ever after= resolution
