Quizplus · Accepted Answer

The scenario mentions that the patient had a severe case of anterograde amnesia after the surgery, which means that he cannot form new long-term memories after the surgery. Therefore, the memories that are severely impaired by the surgery are the episodic memories from after the surgery. Short-term and implicit memory were not affected. Thus, B, C, and D are incorrect choices.
