Here's why it's tricky:
* The question doesn't ask about time. It asks how the brother can help.
* There's no information about how much the brother can do. It only says he could put it together in 6 hours (which is likely a made-up scenario).
How the brother can help:
* Sorting pieces: He can help Jenny sort the puzzle pieces by color, shape, or edge pieces. This makes it easier for Jenny to find the pieces she needs.
* Finding specific pieces: If Jenny is looking for a particular piece, her brother can help search for it.
* Building sections: They could work together on smaller sections of the puzzle, making it feel less overwhelming.
* Encouragement: He can keep Jenny company and cheer her on as she works!
The most important thing is that they have fun working together. 😊
