Three of the sentences below commit number agreement errors. select the sentence that is grammatically correct.
o
there's pencils in the box.
there's something you must know.
there's five marbles on the floor.
o there's several ways to post something online.

There's something you must know.

Explanation:

All of the incorrect sentences contain a subject-verb agreement mistake. The subject-verb agreement refers to that the subject and verb must agree in number (singular or plural).

There's pencils in the box should be There are pencils in the box. As the subject is plural, the verb must be in the plural form as well (are + pencils).

There's five marbles on the floor should be There are five marbles on the floor. Once again, there is more than one marble, so the verb has to be in the plural form (are + five marbles).

There's several ways to post something online should be corrected to There are several ways to post something online. Just like all, both, few, many, and some, several goes together with the plural form of a verb, although in colloquial language you can often hear it used with the singular. Are + several is the grammatically correct option.

There's something you must know is an example of correct subject-verb agreement, as the singular form of the verb (is) is used with the singular pronoun something.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
