Worked solution

- Delta fell from 200 in 2023 to 180 in 2024.
- So declines occurred in both 2023 and 2024.
Answer: In both 2023 and 2024.
The idea
Scan every row rather than stopping at the first decline found. Questions of this shape often have more than one instance.
Shortcut. Only the Beta and Delta rows are not steadily rising; each has one dip, and the dips fall in different years (Beta 2023, Delta 2024).
Common trap. "Only in 2023" — stopping at Beta's dip (200 → 180) and missing Delta's fall from 200 to 180 a year later.
