the earthquake has damaged a lot of the water sources that we are using for people to access water. so, we are trying to assess how many of those have been damaged. for now, we see many 20% are not usable. we're still doing our service and we don't have the final results. of course,if this was more than that, it would pose a problem for the communities because if you don't have access to clean water, immediately, the disease would spread again. >> yeah. beyond the immediate assistance, there's sort of the long-term needs for millions of people at a time when, you know, the world is focused on ukraine. how big of a challenge looking ahead will be the process of rebuilding for these millions of people who will obviously need homes, infrastructure and all of the help they can get?
