Which city is linked to the code 2N?

• A. St. Paul
• B. Canal
• C. Chicago
• D. Buffalo

Answer: (C)

Codes like 2N come from a fixed code chart used in this material, where each city is paired with a unique two-character code. To answer, you look up the code in that chart and identify which city it corresponds to. In this item, the chart maps the code 2N to Chicago. A common way these charts work is by grouping cities into regions and subregions, so the first character hints at the broad area (for example, the Midwest/North Central) and the second narrows to a specific hub within that area; Chicago serves as the representative city for that pairing. The other cities listed don’t carry the 2N code in the chart, so they don’t fit. If you’re ever unsure, keep the code chart handy and practice recalling which city pairs with which code to build familiarity with the mappings.
