Complete the sentence with the correct form of the verb in brackets: 'The printer has run out of paper.' 'I ___ (refill) it now,' Kai replies, making the decision at that moment.
Correct answer
will refill
Explanation
Kai decides how to respond only after hearing about the empty printer, so will expresses the spontaneous decision. Be going to would imply an intention formed before this exchange, contrary to the stated timing.
