[1] tia and jackie are partners in science class. [2] they have a big project to complete and are having trouble agreeing on an idea. [3] jackie would prefer to study geology, but tia is more interested in human biology. [4] ultimately, they decides to study fossilization.

which sentence has a subject-verb agreement error?

The answer is: Sentence 4.

Sentence 4 has a subject-verb agreement error. The subject in that sentence is plural ("they") while the verb is conjugated in the third person singular ("decides").

According to the Subject-verb agreement rule, subjects and verbs must agree with one another in number. Thus, a singular subject takes a singular verb while a plural subject takes a plural verb.

The correct version of sentence 4 is the following: "Ultimately, they decided to study fossilization." The reason behind this is that the subject is plural so the verb must also be conjugated in the plural form.

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.
