Step 1: Understanding the Concept
Some disorders linked to adolescence and mental health are matched here with their meanings.
Step 2: Check each pair
Anorexia nervosa is an emotional aversion to food, so the pair is right.
Amnesia means loss of memory, so the pair is right.
Depression is a persistent state of sadness, so the pair is right.
Step 3: Find the wrong pair
