Answer 1

b. The burning of coal coats the area with black soot.

The 'black triangle' refers to an industrial region in Poland, eastern Germany, and the Czech Republic known for its historical environmental pollution from coal burning, leading to the area being coated with black soot.

Step-by-step explanation:

The industrial area of Poland, eastern Germany, and the Czech Republic is often referred to as the black triangle. This name originates from the environmental pollution that plagued the region during the era of industrialization under communist rule, particularly due to the burning of coal which left the area coated with black soot.

This region, occupied by the modern Czech Republic was historically known as Bohemia and Moravia, and along with Slovakia, formed Czechoslovakia until they became independent nations in 1993.

During the communist period, there was heavy emphasis on industry, which continued after the shift to a market economy post-communism. Poland, for example, which transitioned to a market economy, still maintains a focus on heavy industry, producing cars, buses, helicopters, trains, and military equipment.
