So here we can eliminate their ex near by juice and, uh, one times two less with it too. So we'll be Jude Tim's one. And when, uh Ju so is the event zero for banks and then six plus in the six, so he could do zero Wonder why it's well ah, morning, Dan and ministry and, uh, ministry plus with the drought So he means and then doesn't give us though you could use Oh, so here we have on on Lee eso equation Wanna question Judy and multiple me on this? So one way isn't from blast that so it doesnt implies that the question two technical June, uh managed to terms in question one. So now doomed.
