Q3 had me thinking about how more solutions might exist in the future that aren’t possible now. Here’s a different riddle, where it’s clear that things have changed:
How many ways can you think of to do shopping using a phone, if the phone is:
a) a corded landline with no extra features ☎
b) a mobile phone with text, calculator etc. but no internet/data/browser and no way to install applications that didn’t come built in
c) a smartphone 📱
There are at least three solutions for part a.
