Example:
We would like to define this partition for the purposes of creating a new file system. Also, notice that approximately 4 GB of storage is available for this new partition. This is be determined by examining the total amount of space reported with the backup partition (2) and comparing this information with the existing partition’s total disk space sizes.
I'm not sure how to understand that. What's specifically strange to me is how be is used there. Looks suspiciously like a subjunctive, but I'm not entirely sure, to tell you the truth. Would you agree that this is determined without be would sound equally fine?
