RandomizedControlled Trial on ways of delivering chlorine tablets to treat water. They designed this experiment to address two issues that some public health systems have faced. they want to test whether those who need the product do receive it under each delivery mechanism: if there are people who aren't receiving it who should, this is called overexclusion. they want to test if people who receive the tablets waste them by not using them correctly, which is called overinclusion. Both of these issues could happen under the delivery mechanism.

These issues of "targeting" are also crucial in distributing other health goods, such as insecticide-treatedbednets which help prevent malaria. You have been asked by a policymaker in Kenya to evaluate the best way to distribute bednets, accounting for the trade-offs between overexclusion and overinclusion.

(a) In two sentences or less, why should the policymaker care if there is overexclusion in the provision of treated bednets ?

(b) In two sentences or less, why should they care if there is overinclusion ?
