There / Their / They're is a bird nest in that tree.

There is a bird nest in that tree

Explanation:

There is a bird nest in that tree.

Explanation:

"They're is a bird nest in that tree." is incorrect because that would not make any sense at all since "they're" is a conjunction of the words, "they are", therefore "they're" can be eliminated.

"Their is a bird nest in that tree." is also incorrect because "their" is used to say that something belongs to someone, e.g. "It was their pencil bag." which states that the pencil bag belongs to them, whoever they are.

With the process of elimination and grammatic sense, we can conclude that the answer to fill in this sentence would be "there" for the sentence, "There is a bird nest in that tree."

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
