I want to know the answer to the following question:
Which magazine publication carried a statement from the Human Development Report Office in January, 2011?
All the background I'm provided with is that "In a comment to The Economist in early January 2011, the Human Development Report Office responded to a January 6, 2011 article in the magazine which discusses the Wolff et al. paper.". Is that enough to answer the question?
Answer: yes
