Los Angeles Photochemical Smog Incident: In 1943, a large amount of exhaust gas emitted by automobiles in Los Angeles, USA, produced chemical smoke under ultraviolet radiation, which caused a large number of residents to have red and swollen eyes, tears, sore throat, etc., and the mortality rate increased greatly. Donora Smog Incident:

London Smog Incident: In 1952, 4,000 people died in the first two weeks and more than 8,000 in the next two months due to the accumulation of soot and sulphur dioxide emitted by winter coal burning in London, England.

Yokkaichi Asthma Incident: Around 1961, Yokkaichi City, Japan, due to the serious pollution of the atmosphere by the exhaust gas emitted by the burning of heavy oil from petrochemical and industrial combustion, caused a sharp increase in respiratory diseases among residents, especially the incidence of asthma, with an incidence of about 8% and more than 10 deaths in the elderly over 50 years old. Minamata Disease Incident:

From 1953 to 1956, due to the discharge of mercury-containing wastewater from a petrochemical plant in Minamata City, Kumamoto Prefecture, Japan, people ate fish, shrimp, shellfish and other aquatic organisms contaminated with mercury and enriched with methylmercury, resulting in a large number of residents with a mortality rate of 38%, and 283 people were poisoned with mercury, of which more than 60 died.

A, B, C three answers to the high elimination case is a common method to compare the density of objects, to compare the quality of rice, that is, the fullness of the grain as long as the density of the rice can be compared, so A, B, C three in line with the topic

d Comparing the size of the grains just from the shape of the rice to see whether the grains are full or not, it is impossible to know the grains one by one to compare, and it is not in line with the reality of life, so it is not in line with the topic

Therefore, choose D
