Question
Taller adults tend to have larger feet.
Monaro: “Your dad wears size 9 shoes, and he’s not as tall as my dad. So my dad’s shoe size must be at least 10.”
Kevin: “No that’s not right. My dad’s feet might be bigger than your dad’s.”
If the information in the box is true, whose reasoning is correct?
