Final answer:
China's estimated GDP in 2013 was approximately $13.39 trillion, and while specific figures for 2016 are not provided, it is known to be the second largest in the world at that time, with the United States GDP for 2016 being around $16.7 trillion after adjustment for inflation.
Step-by-step explanation:
The question regarding China's gross domestic product (GDP) for 2016 is within the field of Social Studies, specifically the area concerning economics and international development. China's estimated GDP in 2013 was approximately $13.39 trillion, and by 2016, the real GDP of the United States (often used for comparison) adjusted for inflation was about $16.7 trillion. While the two pieces of information provided don't give a direct figure for China's GDP in 2016, this context allows us to infer that China's GDP was still growing but likely had not yet surpassed that of the United States. Also worth noting is that GDP per capita is often used to provide insight into living standards, which reveals a large disparity between China and the United States due to China's larger population. It is essential to acknowledge that without access to the exact figures for 2016, one can reference China's GDP as the second-largest in the world during that period, with an upward trend from the $13.39 trillion noted in 2013.
