4. Choose the correct form of the verbs. Last month a class of secondary school students (1) was given a half-day holiday by their school after their exams. Two of the students went for a walk but it (2) started to rain, so they went into a second-hand shop to keep dry. All kinds of old furniture (3) were left around the shop. There were bowls and plates everywhere and old photographs and paintings (4) were pushed under tables. The students (5) decided to look at the pictures to pass the time. Most of them (6) were covered in dust. Then one of the students (7) noticed a small picture which (8) was almost hidden behind a cupboard. It (9) showed a vase of flowers which (10) were painted in great detail. The picture (11) wasn’t signed but the shop owner thought it (12) was probably painted about fifty years ago. The students (13) paid £5 for it and (14) took it away. Later they (15) discovered it was five hundred years old. It (16) was sold by a gallery in London last week for one million pounds!
