The hyphen in "one-time winner" is used because:
a. time modifies one winner
b. one is a prefix
c. one-time is a number
d. one and time modify winner

The correct answer is D. one and time modify winner.

A is incorrect because time is the word being modified (described), and not the other way round. B is incorrect because one is a number, and not a prefix. C is incorrect because one-time is an adjective, and only one is a number.

That leaves us with D as the correct answer - both words, one and time, modify the word winner - and because it is a compound adjective, it has to have a hyphen.

answer; (external conflict)

read this passage from the crisis. what rationale is paine using for going to war with great britain? my own line of reasoning is to myself as straight and clear as a ray of light. not all the treasures of the world, so far as i believe, could have induced me to support an offensive war, for i think it murder; but if a thief breaks into my house, burns and destroys my property, and kills or threatens to kill me, or those that are in it, and to "bind me in all cases whatsoever" to his absolute will, am i to suffer it? what signifies it to me, whether he who does it is a king or a common man; my countryman or not my countryman; whether it be done by an individual villain, or an army of them? if we reason to the root of things we shall find no difference; neither can any just cause be assigned why we should punish in the one case and pardon in the other.

it is waged war against an army of countrymen

it would lead to independence from britain

it would be an offensive war

it would be a defensive war
