The diagram shows how bricks are made for the building industry. 

Overall, brick manufacturing consists of seven consecutive steps.


First the raw material, clay, which lies just below the surface of the 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 ones, 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 homogeneous mixture,

which is then either formed in moulds or cut into brick-shaped pieces by means of a wire cutter.

These 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 so-called kiln,

another type of high temperature oven. First they are kept at a moderate temperature of 200 C-980 C,

then at a high temperature of 870 C-1300 C. 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.

  1.The government's investment in arts, music and theatre is a waste of money. Governments should invest these funds in public services instead. To what extent do you agree with this statement?   It is believed that financing activities related to art, music and theatre by governments is misspending and these investments should be rather spent on public services. I strongly disagree with this because these creative activities promote tourism as well as keep the mental well-being of people in a better state. 2.

  International tourism has brought enormous benefits to many places. At the same time, there is concern about its impact on local inhabitants and the environment. Do the disadvantages of international tourism outweigh the advantages? Give reasons for your answer and include any relevant examples from your own knowledge or experience. Write at least 250 words. The growth of international tourism has undeniably brought significant benefits to various destinations. However, alongside these advantages, there is a growing concern regarding the potential negative impact on local inhabitants and the environment. In my opinion, international tourism leads to the exploitation of local resources. On the other hand, it helps in economic growth and promoting peace. One major concern is the potential exploitation of local resources. Uncontrolled tourism development may result in overcrowding, degradation of natural landscapes, and depletion of resources such as water and energy. Additionally, the
