's' is right next to 'd'

My keen attention to detail spotted a typo in the 48 page US Foreign Service Officer Test guide. Imagining the multitudes of Administrative Assistants pouring over the production of the document, I re-read the paragraph to make sure it wasn't an illusion. A federal document with exponential amounts of eyes glued to it for guidance, and not one pair spotted the 'd' that was supposed to be an 's'. I'm comforted by the fact that even the meticulous editors of the US government are not infallible. More so, it reflects on sheer human error. Even with our fastidious strides towards perfection, the 's' key remains right next to 'd'.
