Fill in the blank with an appropriate one-word synonym for the bolded word based on the context clues in the sentence.
Answer:The flight instructor signaled that the training drill would commence at sunrise, requiring every pilot to 【begin】 pre-flight inspections promptly at 0600 hours.
Answer
begin (or start)
In this context, 'commence' means to begin or start an activity. Clues such as 'at sunrise' and 'promptly at 0600 hours' establish that the drill is underway at its initial scheduled time. Therefore, 'begin' or 'start' correctly completes the sentence.
