Read the following passage  and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each for  the question  from 41 to 50. ACID DUST “ Calcite- containing dust particles blow into the air and combine with nitric acid in polluted air from factories to form an entirely new particle – calcium nitrate,” said Alexander Laskin,  a senior  research scientist at the Department of  Energy’s Pacific Northwest National Laboratory in Richland, Washington. These nitrates have optical and chemical properties that are completely different from those of the originally dry dust particles . Due to this , climate models need to be updated to reflect this chemistry . Calcite dust is common in arid areas such as Israel , where scientists collected particles for analysis.     Working from a mountaintop, the team collected dust that had blown in from the northern shores of Egypt, Sinai, and southern Israel. The particles had combined with air containing pollutants that came from Cairo. They analyzed nearly 2,00 individual particles and observed the physical and chemical changes at the W.R Wiley Environmental Sciences Laboratory.     A key change in the properties of the newly formed nitrate particles is that they begin to absorb water and  retain the moisture. These wet particles can scatter and absorb sunlight-presenting climate modelers, who need to know where the energy is going, a new wild card to deal with . Companion studies of dust samples from the Sahara and the Saudi coast and loess from China  show that the higher the calcium in the mineral , the more reactive they are in with nitric acid .And once the particle is changed, it stays that way.         “When dust storms kick up these particles and they enter polluted areas, the particles change,” Laskin said. “ To what extent this is happening globally, as more of the world  becomes industrialized, we don’t know. But now e have the laboratory and field evidence that shows it is definitely  happening. The story is much more complicated than anybody thought .”
