Once again Karim thinks about his sister, who, as you
already know, is a civil engineer. She has had years of
education and has worked hard to be an engineer. Karim
remembers the day when he went to her room and
looked at her school work. Until then he had thought that
she had been drawing things like buildings, bridges, etc.
He was surprised when he saw her work and could not
understand anything. What she was doing was very
demanding, difficult and complicated. There were so
many lines and figures on the paper that he could not
even understand what they signified. He asked his sister
what they were, and was amazed when he learned that a
building would be built according to these drawings.
Until that day, Karim had not thought that civil
engineering could be so difficult. Besides, his sister had
told him that she was merely dealing with the design of
the building. In the following stages, workers would
come into play and would build the building, using various
tools and materials.
