Question Passage:
Every year many people visit Mount Rushmore, where the faces of four U.S presidents were carved in granite by sculptor Glutton Borglum and his son, the late Lincoln Borglum. The creation of Mount Rushmore monument took 114 years and a million of dollars. To move the more than 400,000 tons of rock, Borglum hired laid off workers from it the closed down mines in the Black Hills area, He taught these men to dynamite, drill, carve, and finish the granite as they were hanging in midair in his specially devised chairs. During the carving, many changes in the original design had to be made to keep the carved heads free of large fissures that were uncovered. However, not all the cracks could be avoided, so Borglum concocted a mixture of granite dust, white lead, arid linseed oi] to fill them. Every winter, water from melting snows gets into the fissures and l expands as it freezes, making the fissures bigger. Consequently,.every autumn maintenance work is done to refill the cracks.

Answer the following question:

. Borglum's mixture for filling cracks -

  was very expensive

  was bought from the mines

  was invented by himself

  expands during winter

Question Passage:
erosion is regarded not merely as the physical removal of soil by water and wind, but rather as the ass deterioration of all the component parts of the habitat in Which man and his crops and livestock have to exist. Since there is no conclusive evidence for any major climatic in change in historic times to explain this deterioration, we  must conclude that the eroding of the total environment has been due primarily to thoughtless destruction of the vegetative cover. This has led to deterioration of the micro climate above and below the surface, generally in the | direction of a general drying out of the soil which has exposed it to erosive action of wind and rainfall of high intensity or frequency, and to the loss of organic matter in the soil, thus reducing its capacity to resist erosion by conserving the water that falls on the surface, If everything Possible is done within the total environment to _conserve the naturally planted or cultivated vegetation, this will also sure optimal conservation of soil and water. 

Answer the following question:

Which one is not the driver of soil erosion?

  Water

  wind

  surface water

  rainfall

Answer the following question:

The impoverishment of the world’s habitat is due to-

  man’s irresponsible abuse of the vegetation cover

  gradual deterioration of microclimate.

  drying out the soil
