You open the bench drawer and find a pair of plyers, electrical tape and an old bank draw string bag. Do you want any of the items? After collecting what you need, you need to light up the closet. How are you going to do this?

take the plyers and tape and take a look inside the bag

You want to take the plyers and tape but your pockets are full. Laying them on the bench you reach for the bag and almost get bit by the spider inside. The bag is empty and may be useless. Your next move is to light the closet, but lighting the lantern is not required. This is a little tricky so here is a hint. It's cleverly hidden.

Dump the spider from the bag, put the pliers and tape in the bag, and tie the bag to your belt (belt loop, wrist)

You now have the two items in the bag, but no light in the closet yet. How are you going to fix the the light?

take the mirror and use it to reflect light into the room

Ding! Ding! Ding! We have a winner! You remove the mirror now, prop it up against the door jam and reflect the light from the basement onto the light socket. Let's see if that worked.
