Student query:
For #2, where we have to state that they're both more than 25 years
old, =
should we use some function like "current_year()" to return the
current =
year? (or should we just use 2000?) Since you give us a function to =
return the year x was produced, we need some function like it to =
calculate how old it is...
Either one. Just be clear about what terms you are introducing; i.e.,
what types their arguments are and what exactly they mean.
