The three diagrams highlight a flooding problem in a UK town and outline two solutions to this problem; one solution is less costly but affects the environment more, while the other proposal has a higher cost but is less damaging to the environment. The flooding problem occurs in an area where two river join to form one and the area affected contains residential housing, commercial buildings, and an industrial park.
One solution to the problem is to relocate the affected developments to nearby areas which are slightly further away from the river. The downside of this is that it would be very costly, but the upsides is that it would result in less environmental damage.
The other solution is to dam the two rivers causing the flooding. This is a much cheaper option but would result in more area being taken up by the resulting reservoirs behind the dams, thus leading to more environmental damage.
The process by which bricks are manufactured for the building industry can be outlined in seven consecutive steps. First the raw material, clay, which was just below the surface of soil in certain clay-rich areas has to be dug up by a digger.
Then the lumps of clay are placed on a metal grid in order to break up the big chunks of clay into much smaller areas, which fall through the metal grid onto a roller, whose motion further

segregates the bits of clay. Sand and water are added to make a homogenous mixture, which is then either formed in moulds or cut into brick-shaped pieces by means of a wire cutter.
Those fresh bricks are then kept in a drying oven for at least 24 and a maximum of 48 hours, several dozens if not hundreds of bricks at a time. The dried bricks are then transferred to a socalled kiln, another type of high temperature oven. First they are kept at a moderate temperature of 200 ℃ -1300 ℃. This process is followed by cooling down the finished bricks for 48 to 72 hours in a cooling chamber.
Once the bricks have cooled down and have become hard, they get packaged and delivered to their final destination, be it a building site or storage. (215 words)
