问题如下：
Assume the GDP in Country X of year 2016 and 2017 is $200 billion and $220 billion respectively, using 2016 as the base period, the GDP deflator for 2017 is closest to
选项：
A.110
B.90.9
C.10
解释：
A is correct.
The GDP deflator is calculated as 100*(220/200)=110.
考点： GDP deflator
解析：直接依据定义计算100*(220/200)=110.
GDP deflator is the ratio of that year's norminal GDP to that year's quantity of production valued in Base year price. Here we need to assume the quantity of production of 2016 and 2017 is the same, otherwise, we cannot divide the norminal GDP of 2017 by the norminal GDP of 2016 directly to calculate the 2017 GDP Deflator. However, it is not explicitly stated in the question. I wonder whether there is an error in this question.
