解释:
C An individual’s credit file will show a history of credit requests, with multiple requests causing an applicant’s credit score to decline. A credit bureau score model (rather than pooled model) will result in scores ranging from 300 to 850. A custom model is more expensive to implement than credit bureau scores. -Gross salary with current employer- is an example of a characteristic, with the actual salary number itself representing an attribute.
