A The exhibit's source notes are evidence; the bridge claim is that audit-sampling software would flag unusual transactions faster; the recommendation that an accounting team should use audit-sampling software for routine reviews is the main conclusion; the assumption is that the data used as support measures the same problem that the recommendation is intended to solve.
B The recommendation is evidence; the exhibit is the main conclusion; the caveat proves that the recommendation is unnecessary.
C The exhibit merely provides background; the main conclusion is only that reviewers still need to investigate flagged items; the assumption is that audit-sampling software will eliminate every instance of manual spreadsheet checks immediately.
D The bridge claim is the final conclusion, and the recommendation to use audit-sampling software for routine reviews is just an example of the evidence.
