Which of the following is not true with reference to English grammar?
1
When modals like should, could, need, must, etc. are used in the formula 'modal + have + V3', there is a hidden meaning opposite to the sentence's meaning.
2
Do, have, and be, the Primary Auxiliary verbs are only used as helping verbs.
3
To + base form comes after need and dare.
4
If need/dare are used in negative sentences, 'not' is followed by a bare infinitive i.e. only 'V1' and not 'to + V1'.
