stumped

By a preschool readiness worksheet, no less!

Here are the directions:  “Decide how the first 2 pictures in each row relate to each other.  For example, you can live in a house or a tent, but the house is fancier.  Now think about the glass.  Using the pictures from the bottom of the page, cut out the one that could also be used like a glass but is just not as fancy and paste it in the box next to the glass.”  Sounds simple…and the first question is.  There’s a paper cup in the pictures on the bottom of the page. 

Here’s the one I am fairly sure Logan won’t get:

Giraffe is to palm tree as mushroom is to ____________.

Now, I can see the correct answers, but how exactly would you pick BUG as the right one? 

It will be interesting to see how this works…
