The sentence "either the farmer or the hunters is literate" is not correct because it contains a subject-verb disagreement. Here's why:
The subject of the sentence is "either the farmer or the hunters." In this case, "either...or" is a correlative conjunction used to connect two subjects. When two subjects are connected by "either...or," the verb should agree with the subject closer to it, in this case, "hunters."
Since "hunters" is plural, the correct verb form should be "are" instead of "is." Therefore, the correct sentence would be: "Either the farmer or the hunters are literate."
