Fill in the blank with suitable Conjunction: I will call you later _____ I am done with my chores.
- a.once
- b.because
- c.as
- d.so
Answer: (A) once
'Once' used as a conjunction means 'as soon as' or 'after', so the sentence says the call will be made after the chores are finished. 'Because' would make the chores the reason for calling, 'so' introduces a result, and 'as' (while or because) does not give the 'after completion' sense. Grammar point often tested in error-spotting: in time clauses beginning with once, when, after, before, until or as soon as, the present tense is used for future meaning (once I am done, not once I will be done).
