Transcript text: What is wrong with the following flowchart? A is the priming input. B is a selection. C is the main processing. More than one answer may apply. Select one or more: a. Another rectangle with A should follow the Yes selection of B, but before C. b. Another rectangle with $A$ should follow the No selection of $B$. c. Another rectangle with A should follow C . d. The loop back should return below $A$. e. Another diamond with B should follow C.

Solution

Solution Steps

Step 1: Analyze the flowchart

The flowchart starts with process A, followed by a decision B. If B is true, process C is executed. If B is false, the flow loops back to the start. The issue lies in where the loop returns.

Step 2: Identify the incorrect loop return

Currently, the loop returns to the beginning, directly before A. This means that A is always executed, regardless of whether the decision B is true or false. In this scenario, C will only be executed if B is true. However, it also will be followed by A after the "Yes" decision takes place.

Step 3: Identify the correct loop return

The loop should return below A so that A is executed only once at the start. Subsequent executions should only depend on decision B. If the loop returns below A, the “Yes” path executes C and then continues to B for the next iteration of the loop. The "No" path would skip C and move directly to B. This makes A a "priming input," as described in the prompt.
