Hey, there! It actually looks like you're looking at a verb tense agreement error. Subject-verb agreement errors have to do with the *number* of both subject and verb agreeing (for example, if it had said "will they goes with us" you'd know that was a subject-verb agreement error because "goes" is a singular verb and "they" is plural).
The problem in this sentence, though, is that "goes" is the present tense form of "go," but "will" indicates that the question should use the future tense. So, "will he go to the lake with us on Saturday?" agrees on verb tense while "will he goes to the lake with us on Saturday" does not.
Let me know if you have any other questions!

For the sentence "Byron is seeing Diane for three months now." I know the error is "is" and it should be "Byron has been seeing Diane for three months now." Is the error because "is" indicates the idea that something is happening now, at this very moment and has been should be used because it shows that something started in the past and has continued up until now?02/29/20

Hey, yes, you’re correct! If you want to get even more technical with it, “is” is in the simple present tense (where the action is happening right now, with the present moment being the main topic of discussion). “Has been,” however, is the present perfect tense, which means that an action has been happening in the past and is continuing through the present moment. The exact time frame doesn’t matter for the present perfect tense, but it’s used when you’re talking about something that has occurred in both past and present. So, basically what you said, but with fancy vocabulary!02/29/20
