Read the passage below then pick out ONE best option ( A,B,C or D ) to complete each sentence:
About 120 people have been infected with the virus of bird flu since it spread in Asia in 2003, most of them contacted with chickens. More than 60 people have died from the virus. While some of those infected fell ill after eating sick chickens, doctors cannot quite determine if they were ill because of eating or handling the chickens. But the question about whether eggs are safe has assumed danger since healthy chickens carrying the virus were discovered in Indonesia recently. The chickens do not fall sick and continue laying eggs even though they carry and shed the virus. Scientists cannot agree whether the content of the eggs from such chickens are free from the virus, but they say there is some risk because the surface of the egg shells may still expose to virus. Health experts are extremely concerned about infected birds and poultry which do not show any symptoms because they render the virus so it is much harder to detect and control the illness. Some experts have warned against eating eggs.
