Again, it's fascinating testimony from all of our witnesses.
I'm going to ask one initial question of Professor Diamond. I'm going to touch on a number of areas you have suggested for improvement and put those questions to Mr. Khosla.
I noted that in your testimony, when you were discussing the review and assessment process, you suggested that there are two questions that need to be asked. One is, do we need the function provided for by that chemical, and two, do we need that product?
Who are you suggesting would actually make that assessment of whether a product or chemical is needed?
