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.

Q: Passage: Digital distribution of movies has the potential to save money for film distributors.  To print an 80-minute feature film can cost US$1,500 to $2,500, so making thousands of prints for a wide-release movie can cost millions of dollars. In contrast, at the maximum 250 megabit-per-second data rate (as defined by Digital Cinema Initiatives for digital cinema), a feature-length movie can be stored on an Commercial off-the-shelf 300 Gigabyte hard drive for $50 and a broad release of 4000 digital prints might cost $200,000. In addition hard drives can be returned to distributors for reuse. With several hundred movies distributed every year, the industry saves billions of dollars. The digital-cinema roll-out was stalled by the slow pace at which exhibitors acquired digital projectors, since the savings would be seen not by themselves but by distribution companies. The Virtual Print Fee model was created to address this by passing some of the saving on to the cinemas. As a consequence of the rapid conversion to digital projection, the number of theatrical releases exhibited on film is dwindling. As of 4 May 2014, 37,711 screens (out of a total of 40,048 screens) in the United States have been converted to digital, 3,013 screens in Canada have been converted, and 79,043 screens internationally have been converted.
Question: As of 4 May 2014, how many screens world-wide have been converted to digital?

A: number

Q: Passage: Unemployment hovered at 8-10% after the start of the economic slowdown in 1999, above the 7% average for the 1990s. Unemployment finally dipped to 7.8% in 2006, and continued to fall in 2007, averaging 6.8% monthly (up to August). Wages have risen faster than inflation as a result of higher productivity, boosting national standard of living. The percentage of Chileans with household incomes below the poverty line - defined as twice the cost of satisfying a persons minimal nutritional needs - fell from 45.1% in 1987 to 11.7% in 2015, according to government polls. Critics in Chile, however, argue that poverty figures are considerably higher than those officially published; until 2016, the government defined the poverty line based on an outdated 1987 household consumption poll, instead of more recent polls from 1997 or 2007. According to critics who use data from the 1997 poll, the poverty rate goes up to 29%; a study published in 2017 claims that it reaches 26%. Using the relative yardstick favoured in many European countries, 27% of Chileans would be poor, according to Juan Carlos Feres of the ECLAC. Starting in 2016, a new Multidimensional Poverty Index is also used, which reached 20.9% using 2015 data.
Question: How many percent difference is there between the data in the 1997 poll of the poverty rate compared to the study published in 2017?

A:
number
