What personal behavior change during her Vienna period drew concern from a teacher?

• A. She started a diary
• B. She started doing drugs
• C. She learned to drive
• D. She joined a sports club

Answer: (B)

Turning to drugs during the Vienna years signals a serious shift in how she’s coping with living abroad and the clash between two cultures. In that period, a teacher would notice if her behavior becomes risky, unpredictable, or unhealthy, because it affects concentration, safety, and performance—red flags that go beyond ordinary teenage changes. Other options—keeping a diary, learning to drive, or joining a sports club—are typically harmless or positive changes that wouldn’t by themselves raise concern. So the drug-use change best fits the idea of a warning sign that drew a teacher’s attention.
