Pick up the most effective words from the given words to fill in the blank to make the sentence meaningfully complete.
The taxi drivers were ________ regions to resolve the issue ________ before it got out of hand and out of reach.
The first blank suggests that regions were delegated and the most fitting word for that is assigned. The other words might mean similar to that of being delegated, however in comparison are not better than assigned.
The second blank suggests that it was done with quickly and the most fitting word for that is hastily. Impulsively might have negative understanding, properly and timely are not the suggested meaning and broadly does not fit in meaningfully. Hence, the right answer is the fourth option.
