I have a different answer to number 3.......It's the name of the state flower for Alaska.

When the words "we hear" appear in a question it usually means the answer sounds similar. ie sounds like "Alaska." which is the 49th state.
Wheelbarrow is one of the other answers in this 100 question quiz, so unlikely to be so similar an answer but thank you both for offering suggestions.
