Event Silurian tree quiz

[GForce0]

Hi, for the tree quiz it asks which type has the least dual type as of generation 5.
Options: normal, steel, fire, dark.
From the table on this site http://bulbapedia.bulbagarden.net/wiki/List_of_type_combinations_by_abundance
I count normal 32, steel 34, fire 24, dark 30.
But when I click fire it says it's wrong.
If it is gen 5 only, then then number are normal 9, steel 9, fire 10, dark 9.

Am I misinterpreting the question? Does anyone have experience with this question and know how I should solve it?

Check this list. As you can see, Normal has the fewest dual typings, having 9. Fire has 13, Steel has 14, and Dark has 13.

Ooh you have to count number of type combinations! I thought how many individual pokemon there actually are with the type combinations. Thanks!
