Neither, either, so

A: I can't go to the presentation.

B: ____

• Neither can't I

• Neither can I

• So can I

Answer explanation

➪ We use so + auxiliary verb + subject in affirmative sentences and neither + auxiliary verb + subject in negative sentences.  
➪ Neither/nor is a negative word, like not. For this reason, the auxiliary verb after neither should be affirmative.

Answer explanation

➪ We say neither + affirmative auxiliary verb + subject. And we use either at the end of a sentence with a negative verb.

B: Neither ____

Answer explanation

➪ The verb have is an auxiliary verb in the form have got.
➪ After neither we have to use an affirmative auxiliary verb because neither is a negative word, like not.

➪ We can also use too at the end of affirmative sentences to mean the same.
