Question

what does the sound of birds chirping after a storm signify?
that the storm is over.
that the storm will blow through again shortly.
that the temperature is going to increase.
that the plants have been destroyed.

Explanation:

Birds chirping after a storm is a common natural behavior. When a storm passes, the environment becomes more stable and safe. Birds start chirping to communicate, forage, and re - establish their territory. There is no scientific basis to suggest that it means the storm will return shortly (as storms are complex meteorological events not signaled by bird chirping in this way). Also, bird chirping after a storm has no direct relation to a temperature increase (temperature changes are part of the overall weather system but not specifically signaled by post - storm bird chirping in the way described) or plant destruction (birds would not chirp in a celebratory or signaling way if plants were destroyed as it would be a negative impact on their habitat).

Answer:

That the storm is over.
