Which of the following seasons is NOT mentioned in the text?

The correct answer is Monsoon because the text specifically addresses the four traditional seasons—Spring, Summer, Autumn, and Winter. Monsoon, while it can be significant in certain regions, especially in South Asia, is typically considered a climatic season rather than one of the four main seasonal divisions recognized globally. Therefore, if the text focused on the general concept of seasons, it likely did not include Monsoon among its discussions. Recognizing that Monsoon is not a universally acknowledged season like the others helps clarify why this option stands out as the correct choice.
