(7) On R1, R2, R3, and static routes configured to 192.168.3.0/24, the default route is configured by R4.

Experiment conclusion: the problem is to carefully analyze the path of the network and configure a static route. No matter which network you arrive at, you must configure a static route. Otherwise, the route cannot be reached.
