Directions (1-3) : Read the following passage carefully and answer the questions given below it.

Vibrio parahaemolyticus is a bacterial organism that has been isolated from sea water, shellfish, finish, plankton and salt springs. It has been a major cause of food poisoning in Japan, compelling the Japanese to do several studies on it. They have confirmed the presence of Vibrio parahaemolyticus in the North and Central Pacific, with the highest abundance in inshore waters, particularly in or near large harbours.   A man, named Nishio, studied the relationship between the chloride content of sea water and the seasonal distribution of Vibrio parahaemolyticus and concluded that while the isolation of the organism was independent of the sodium chloride content, the distribution of the bacteria in sea water was dependent on the water temperature. It has been isolated on high frequencies during summer from June to Sepetember but was not isolated with the same frequency in winter. Within four of five days after eating contaminated foods, a person will begin to experience diarrhoea, the most common symptom, this will very often be accompanied by stomach cramps, nausea and vomiting, headache and fever, with or without chills, may also be experienced.
