  2. A delivery manifest shows: Manifest A: 884 packages, 12 routes, 73 stops Manifest B: 884 packages, 21 routes, 73 stops

    Answer: Route count is transposed in B

  4. Compare the sector codes: Code A: RS-44-1192-B Code B: RS-44-1912-B

    Answer: The four-digit group has a transposition

    The four-digit group is '1192' in Code A but '1912' in Code B — positions 2 and 3 within that group are swapped.
