The old woman feeds pigeons in the park every day.

He was put in prison.

He is an expert in ethology, and his research is highly regarded worldwide.

He is good at playing Beethoven's concertos.

My father works at a local broadcasting station.

He is good at playing Beethoven's variations.

He composed a fantasia for the piano.

Conversations with him are always complex, like a game of go.
