List the numbers 1 through 8 in the table below. Each number represents one of the described situations on the page below. In the table, next to each number, place the capital letter of the control goal that best matches the situation described. Hint: Some letters may be used more than once in each situation. Conversely, some letters may not be used at all.

- The following is a list of six control plans from this chapter, and these are followed by a list of five definitions or descriptions of control plans. Match the five definitions or descriptions with a control plan that best matches the definition. Because there are six control plans, you should have one letter left over. Control Plans A. Limit checks B. Tickler files C. Public key cryptography D. Compare input data with master data E. One-for-one checking F. Manual reconciliation of batch totals (hash totals) Definitions or Descriptions 1. Determines if a customer number has been input correctly. 2. Ensures that transmitted messages can be read only by authorized receivers. 3. A control plan that confirms a value that was entered is within a valid range. 4. An area (electronic or manual) where documents or other items are stored that need follow-up. 5.
