Final answer:
The therapist is likely to ask Gina to first imagine registering for a college course, as this is the scenario that induces the least anxiety for her.
Step-by-step explanation:
Gina's experience with test anxiety is a situation where systematic desensitization, a technique often used in cognitive-behavioral therapy to help individuals overcome phobias and anxiety, can be useful. In Gina's case, her therapist would likely start with the least anxiety-provoking scenario and gradually work up to the most fear-inducing situation.
Since registering for a course causes her only mild anxiety, it is a logical starting point for therapy. Thus, the therapist is likely to ask Gina first to imagine registering for a college course, which is option (d), before progressing to more anxiety-inducing scenarios such as studying, waiting for the test to be handed out, and actually taking the test.
