Warm up
Sometimes it is easy to identify gender with names, especially if the name is taken from a religious tradition. Abraham comes to mind, or Eve. So one day, in a schoolyard, Abraham is looking at Pat, and Pat is looking at Eve.
Can you (reasonably) know if a boy is looking at a girl? [I don't know... I mean I don't know the answer ...]
Seriously?
You're probably uncertain about Pat: Patrick? Patricia?
Hm. Do you need a hint... [Ok. A hint please...]
Does it matter?[Sorry. Of course it matters whether Pat is a girl or a boy - how could it not?]
If you think it matters, you're both right and wrong. You're right in the sense that it makes a difference. But you're wrong that it matters for the answer: if Pat is a girl, the boy Abraham looks at a girl. But if Pat is is a boy, then he is looking at the girl Eve. So the answer is: yes, you can reasonably know that a boy is looking at a girl. Often, you just need to enumerate all possibilities...
Now: why "reasonably"? Well, I can't exclude that some parents named their daughter Abraham, or that they were confused about Eve ... but hey, it's just a puzzle.
