Final answer:
Transitions can reveal information about the time frame or setting of a story. This can include introducing the setting, foreshadowing a problem, showing a change in weather, and indicating the preparedness of the birds.
Step-by-step explanation:
The transitions listed in the question can be matched with different aspects of the story's time frame or setting. For example, the transition 'On a mango tree in a jungle' introduces the setting of the story. The transition 'Before the onset of the rainy season until they had enough to see them through the rainy season' reveals the time frame before the problem in the story arises. The transition 'Soon the rains came. It continued raining for many days' indicates a shift in the weather.
