Can I answer "Yes, you need/have to." to question beginning with "Must" or "Should"?
I saw just few conversation forms from my book. I want to know if there are more possible answers to this type of question forms.
Example1 from my book:
A: Must I go to school?
B1: Yes, you must (= you have to).
B2: No, you don't have to.
B3: No, you don't need to.
Question1: Since B3 is correct, I'd like to know if B4 (as below) is a possible answer to sentence A.
[B4: Yes, you need to. (I made up)]
Example2 from my book:
C: Should I eat dinner?
D1: Yes, you should.
D2: No, you shouldn't (= should not).
D3: No, you don't have to.
D4: No, you don't need to.
Question2: I think 'must' and 'should' are similar.
So could [D5, D6 (as below)] be a possible answer to 'sentence C'?
D5: Yes, you need to. (I made up)
D6: Yes, you have to. (I made up)
Any keywords or suggestions are all welcomed.
If there is anything wrong in my opinion, please help to correct it. Thank you for your attention.
