Step-by-step explanation:
The number of User Criteria Records that may be applied to a single KB or KB Article is unlimited. According to the given information, there were 294 KBAs that qualified on one or more criteria at the global scale. These KBAs were categorized based on the number of taxon groups that met the criteria. Some sites met the criteria for multiple taxon groups, while others met criteria for only one taxon group.
The greatest number of sites, 94, met the KBA criteria for two taxon groups. This indicates that a single KB or KB Article can have multiple User Criteria Records applied to it.
