China is currently implementing a "soybean action plan" to provide urban and rural residents, especially elementary and middle school students, with high-quality soybean processed products to address the lack of high-quality protein intake. In-plant food production, only soybeans can be directly produced in large quantities. Experts say that at present, the proportion of high-quality protein foods in China's food consumption is relatively small, especially inadequate quality protein intake of rural residents. The most accurate recap of this passage is:. ['The "Soybean Action Plan" is targeted at urban and rural residents, especially primary and secondary school students.', 'Soy is the only high-quality protein food that can be directly produced in large quantities in plant food production.', 'At present, the problem of insufficient protein intake in urban and rural residents, especially rural residents in China.', 'China implements "Soybean Action Plan" to solve the problem of insufficient high-quality protein intake of urban and rural residents.']
