If a certain brand of chemical fertilizer production enters the river, its wastewater discharge will cause red trout to not spawn, which will reduce the number of fish. A chemical factory built not far from the river produced this brand of chemical fertilizer. The number of ovulations of red trout raised by farmers in the watershed has dropped dramatically, so this chemical plant must have polluted the river water when producing fertilizer. Which of the following reasoning errors is most similar to the above reasoning? ['Malnutrition is easy to get sick. Lee is very fat but he has no malnutrition after checking various indicators, so he is definitely not easy to get sick.', "Severe insomnia often stays up late, Zhang is a university teacher and often stays up to work until two o'clock, so Zhang is likely to be a severe insomniac.", 'People who test positive for Helicobacter pylori will get stomach ulcers, and Zhang will have stomach ulcer disease, so Zhang must be positive for H. pylori.', 'People who eat fatty meat can cause an increase in the incidence of cardiovascular disease. Recently, Pharaoh went out to eat twice and ate meat twice. He gained weight and must have a heart disease.']
