With all the geeks that the government has employed...it’d seem like you’d dispatch a dozen down...let the PhD guys test through things, and reach some conclusion. The fact that kids within these families aren’t affected, would lead me to a totally different scenario...and I’d be asking if the wives work in the embassy itself.
I know it says that children of these families haven’t been affected, but in my mind, I think the clarifier “yet” could be added. Perhaps their hearing will be affected as they get older?
