Answer:
If the mom uses the bigger plunger, the strength of the "vaccum" is greater
Step-by-step explanation:
After the plunger is attached to the hole, when it is pulled back, everything in there is getting sucked up, causing a vaccum. The sudden force of pressure loosens the clog in the kitchen sink. The wider the plunger is, the greater the force. It can't be to big though.
