Bpp revision kit Q3 Becker-Self-review threat

I do not have a copy of the kit but in another version of this past exam question is states that recruitment services create threats of self-interest, familiarity and intimidation (I don’t see self-review).
A “management threat” that is created when an audit firm undertakes an activity that is management’s responsibility, is not a separate category of threat. As the provision of recruitment services illustrates the threats that may arise fall into other categories.

An example of a management responsibility that would give rise to a self-review threat would be if the auditor assumed responsibility for an amount in the financial statements (e.g. a valuation).
