Complete the food critic's dramatic review of a disastrous baking show finale.
The judges ______________________________________ the sudden explosion of frosting, given their genuinely horrified expressions. To prevent this culinary catastrophe, the industrial mixer _________________________________________ long before Chef Pierre decided to add the dry ice.
The judges can't have been expecting the sudden explosion... the industrial mixer would have had to be unplugged...
can't have been expecting: We use can't have been + -ing to make a strong negative deduction about an ongoing action in the past. The context ("horrified expressions") tells us it is a logical impossibility that they were expecting it.
would have had to be unplugged: This highly complex form combines a past hypothetical conditional (would have), a past necessity (had to), and a passive infinitive (be unplugged) to describe a requirement that was not met in a hypothetical scenario.
