Sunflowers in the farmyard

Because I was too early for the exam at the computer centre, I had time for a look around in the neighbour hood unfamiliar to me. It wasn't very inspiring. The computer centre was on an industrial estate on the outskirts of Maastricht. There were cows on the meadows and in the distance I could see the hills. Passing a farmstead, I saw these sunflowers.

The exam went well, I guess. I answered all questions and I hope to receive the message in a few weeks, if they were all the best answers.
