   • Здесь мы также говорим о действии в прошлом, поэтому используем Past Simple: allowed.
3. Then they simply (4) … (to reposition) the doors.

Теперь давайте соберем все вместе:

Historians tell us that the problem of pollution existed even in ancient Troy, but it was very simple. The citizens of ancient Troy allowed their refuse to accumulate on the floor until there was such an amount that their doors would not open. Then they simply repositioned the doors. The decrees issued to decrease pollution were recorded as long ago as the Middle Ages. In England, smoke-abatement law was passed in 1273, and in 1306 a man was executed for burning coal. However, the Industrial Revolution changed all prior concepts of pollution. The introduction of power-driven machinery created a pollution problem that has increased steadily from the mid-eighteenth century to the present time. The results of industrial pollution are water and air toxification, respiratory diseases, and even death. That prompted the Environmental Protection Agencies to establish laws to regulate levels of air and water pollution.
