I think this is just a followup research on how affective is the policy. Is the acceptance high. Are there still those wearing white n why. I think la. I have explained before, even after a policy is already implemented, gov will still keep track n do tests to see how affective is the policy. To make sure higher rate of success.

I think la. Coz it doesnt make sense to make a study on black shoe when its already enforced. 🤔
