Question 2: D.

This topic examines the ability of image analysis and agricultural production in China.

Question 1: According to the map information, the soybean planting area in Heilongjiang has decreased and the total output has increased, that is, the output per unit area has increased. The increase and decrease of soybean planting area in Inner Mongolia and Jilin Province are roughly the same. The latitude of Liaoning province is lower than that of other three provinces, and the heat condition is better. Soybean production in Inner Mongolia increased the most, mainly due to the input of agricultural science and technology. Therefore, item B is correct.

Question 2: Due to the influence of production and marketing income, the most likely crop to be replanted is corn, winter wheat is mainly suitable for planting in warm temperate North China, and cotton and rape are not suitable for planting in Northeast China.
