Choose the right option. Susan ... lobster before.

The correct answer is 'has never cooked'. This is because 'before' indicates that the sentence should be in the present perfect tense, which is formed with 'has/have' + past participle. Since Susan is singular, we use 'has'. The word 'never' goes between 'has' and the past participle 'cooked'. Therefore, the correct sentence is: 'Susan has never cooked lobster before.' Answer: has never cooked
