right? No, I don't. I think very good point. No question. So I think we have to be exactly, I think we need to bring in other, capacity is not fixed. Capacity can be enhanced, capacity can be reinforced, even I think can be built and even can be taken as an outside energy. So World Bank can create more basically can put in money. Absolutely. I think I need to be a little bit more careful there. It's not that, so no, let's not assume that the system capacity and constants are fixed. So the question basically, do we need anything else? Because I'm also teaching this similar class at top. So I think we did pose this question. So, and I'm asking maybe you guys also also that okay. So is this a more or less general abstract level of things that we need to do to start addressing the problem? Then we'll get into very quickly our arsenic problem, how this can be applied in real time. So I don't know how much time do we have on image? We have about 10 or 15 minutes. Okay. Yeah. All right. So let's do the I think maybe I'll just go into this. Could you could you just go back one for a minute to the diagram to the list you had you said is you know the question marks at the end is that is that is that sufficient is that do we need anything else like one question you raise I think I need to use my uneasiness with that list is that if you're going to act adapt, adaptively, if you're going to continue to review and change what you're doing
