During database startup， he discovers that one of the disks crashed， resulting in the permanent loss of a read-write USERS tablespace. The USERS01.dbf datafile belongs to the USERS tablespace and is 500 MB in size. He needs to recover the USERS tablespace from the backup. While reviewing the backup details， he discovers that the most recent available backup is five days old. This backup was taken when the USERS tablespace was read-only. After correcting the hardware problem that caused the failure， what should Adam do to recover the USERS tablespace？（）
