When uncontrollable factors such as lack of rain cause farmers' wheat crops to fail, fertilizer and seed dealers, as well as truckers and mechanics, lose business, and fuel suppliers are unable to sell enough diesel fuel to make a profit. Which one of the following claims follows logically from the information above? ["Farmers are not responsible for the consequences of a wheat crop's failing if wheat growth has been affected by lack of rain.", "The consequences of a drought are not restricted to the drought's impact on farm productivity.", "A country's dependence on agriculture can lead to major economic crises.", 'If several of the businesses that sell to farmers do not prosper, it is because farming itself is not prospering.']
