Select the correct verb conjugation. She aun really good doctor. Seleccione una: a. knows b. know

She knows really good doctor. The correct answer is "a. knows." Remember, when the subject is third person singular (like 'she' or 'he'), we typically add an 's' to the base form of the verb in the present tense! Now, think of it this way: if you were to say, "I know" or "You know," you're using the base form because you're referring to yourself or someone else. But when it’s “she” or “he,” it gets a tiny bit of flair with that ‘s’!
