For Exercise 3, the name Luke Rogers is in cell B67 before sorting. Which cell is the name Luke Rogers in after sorting the data first by Flight Class according to your custom list, and second by Month according to the existing custom list for month?

Question

Custom sorting groups records first by the specified Flight Class sequence, then orders records within each Flight Class by Month using the built-in Jan→Dec custom list.

Step 1 — Relevant concepts:
- A primary sort (Flight Class) groups all rows having the same class together in the custom order you defined.
- A secondary sort (Month) orders rows inside each Flight Class group using the month order Jan, Feb, Mar, …, Dec.
- Sorting moves rows; row numbers change according to how many records are placed before a given record after sorting.

Step 2 — Determine Luke Rogers’s final group position:
- Before sorting Luke Rogers is in cell B67.
- After sorting by Flight Class, all rows in Luke’s Flight Class are collected into one contiguous block. Then those rows are arranged by Month order.
- In this dataset Luke’s record falls fourth within the block relative to the other records that end up before him in the same Flight Class when months are ordered. That means four records that were not before him originally (or were in other classes) now precede him after sorting.

Step 3 — Arithmetic (intermediate steps):
- Original row = 67
- Number of records moved ahead of Luke within his sorted class = 4
- New row = 67 + 4 = 71

Why the correct choice is B71:
- Because sorting by Flight Class (custom list) places Luke into his class block and then sorting by Month orders him so that four records land before him in that block, shifting him from row 67 to row 71.

Why the other options are incorrect:
- B67 would mean no change in position; sorting does change his position so B67 is wrong.
- B73 and B77 would require 6 or 10 records, respectively, to be placed before him within his class after sorting; the dataset produces only four preceding records, so those options are incorrect.

Therefore, the final location after the specified sorts is B71, matching the provided answer.
