Choose the correct option to fill up the blank in the given sentence:
Normally, a thunderstorm lasts about 45 minutes but under certain conditions, the storm may_________, becoming ever more severe for as long as four hours.
Solution
✅ Correct Option: 1
The clause 'becoming ever more severe for as long as four hours' shows the storm continues instead of ending, so 'persist' (continue to exist) fits. 'Vacillate' means waver, while 'wane' and 'disperse' mean weaken or scatter, which contradict the context.
