This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Passage: While reliable figures are difficult to obtain, estimated global sales of The Hobbit run between 35 and 100 million copies since 1937. In the UK The Hobbit has not retreated from the top 5,000 books of Nielsen BookScan since 1995, when the index began, achieving a three-year sales peak rising from 33,084 (2000) to 142,541 (2001), 126,771 (2002) and 61,229 (2003), ranking it at the 3rd position in Nielsens "Evergreen" book list. The enduring popularity of The Hobbit makes early printings of the book attractive collectors items. The first printing of the first English-language edition can sell for between £6,000 and £20,000 at auction, although the price for a signed first edition has reached over £60,000.
Question: What year were the most copies of the Hobbit sold?

Passage: According to the United States Geological Survey, U.S. domestic marble production in 2006 was 46,400 tons valued at about $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production (for aggregate and industrial uses) in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate. U.S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for (finished) Marble Index has shown a growth of 12% annually for the 2000–2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile.
Question: What year was marble valued higher when averaged by the ton?
