Zap does zip only if zop. Zop is only if zip is done by someone. Zup does zip. Does zap do zip? Explain your reasoning.
user
So,
zap -> zip, if zop (which requires zip to be done before)
zup -> zip

Therefore, zap does zip only if zip has been done before, otherwise it does not. Zup is not doing anything in this example. I could also formalize this in Python code, if you like.

You say that Zup is not doing anything, but I specifically said that Zup does zip. Fix your logic and try again, please.
user
I apologize, you are correct. Here is the correct construction:

Zup does zip.
Zop is only if zip is done by someone. Therefore, zop.
Zap does zip only if zop. Therefore, zap does zip.

In conclusion, zap does zip.
