                  16. People of a village are totally dependent on the farmers for their daily food items. Farmers grow new seeds by checking
                     the weather conditions every year. An AI model is being deployed in the village which predicts the chances of heavy
                     rain to alert farmers which helps them in doing the farming at the right time. Which evaluation parameter out of
                     precision, recall and F1 Score is best to evaluate the performance of this AI model? Explain.      2

                     sports and painting. He was quite curious when Ananya told him that he too possessed all these intelligences like every
                     human being does, but only at different levels. He wondered which intelligence she was talking about. Can you help
                     Ashwat in learning about different types of intelligences by naming and explaining any four types of intelligences?  4
