What must you do to allow write access to the three subnets while allowing read-only access to all other subnets in this scenario?

Exhibit:

In reference to the NFS export-policy rules shown in the exhibit, NFS clients mounted to /data1 from the 192.168.1.0/24, 192.168.2.0/24 and 192.168.3.0/24 subnets are able to mount /data1 and read files but are unable to edit files or write new files. All other subnets require read-only access to /data1.
