Answer :
An eleven percent growth in China's domestic product indicates an overall economic growth, not specifically the growth rate of wheat production. China's agricultural exports have grown, influenced by global economic factors, and these export growth rates are separate from the domestic product growth. The correct choice is option (C).
If China's domestic product grew by eleven percent in the previous year, it implies that China's overall output grew by eleven percent. This does not necessarily mean that the production of wheat specifically grew by that same amount; it could be more or less, as this figure represents the aggregate growth of all sectors in the economy, which includes agriculture, industry, services, and others. Considering that China is the world's largest wheat producer, it is possible that wheat production contributed to this growth, but the statement alone does not confirm the growth rate of wheat production specifically.
Looking at historical data, we know that China's agricultural product exports have seen rapid growth, with the General Administration of Customs reporting a 9.8 percent increase in 2008 to $40.19 billion. However, this growth rate applies to all agricultural exports, not just wheat, and reflects only the export side of the agricultural sector.
It is also important to remember that fluctuations in export amounts can be influenced by global economic conditions, such as the financial crisis and economic downturn at the end of 2008, which led to a decrease in the amount of exports. Therefore, growth in domestic product and export growth rates might diverge.
Thus, the correct answer to the student's question is option C) China's overall output grew by eleven percent.
