India's monsoons are seasonal. What does this reveal about the monsoons?

India's monsoons are seasonal and this reveals that there is a definite kind of pattern about the occurrence of the monsoon in India. In a country like India the monsoon occurs in certain months of the year throughout the country. In other months there is no rainfall. The summer and winter months in India are also very prominent along with the months for monsoon. The pattern of the monsoon is seldom broken. The monsoon might get delayed or come quicker, but it will definitely occur. This pattern has never changed.

I'm not sure if there are choices you can choose from but here is my answer:

It reveals the fact that India's monsoons occur frequently in a pattern because seasons are in patterns as well.
