Question 13
A robot knows five flower types from this table.

In English, each row lists petals; leaves; colour; scent; stem:
- Tulip: 6; long and smooth; red/yellow; mild; smooth.
- Daisy: 10-20; medium-sized; white/yellow; mild; thin.
- Rose: 10-20; small and pointed; red/pink; strong; thorny.
- Camellia: 10-20; medium-sized; pink; mild; thin.
- Marigold: more than 20; large and round; yellow/orange; strong; smooth.
The beaver grows one of these types. Each question asks about one feature, and the beaver answers accurately. What is the minimum number of questions that guarantees identifying the type?
Editorial convention: a colour answer gives the actual observed colour of the individual flower, not the entire list of possible colours printed for its type.
