Problem: Please answer a question about the following article about Kanye West:
The College Dropout was eventually issued by Roc-A-Fella in February 2004, shooting to number two on the Billboard 200 as his debut single, "Through the Wire" peaked at number fifteen on the Billboard Hot 100 chart for five weeks. "Slow Jamz", his second single featuring Twista and Jamie Foxx, became an even bigger success: it became the three musicians' first number one hit. The College Dropout received near-universal critical acclaim from contemporary music critics, was voted the top album of the year by two major music publications, and has consistently been ranked among the great hip-hop works and debut albums by artists. "Jesus Walks", the album's fourth single, perhaps exposed West to a wider audience; the song's subject matter concerns faith and Christianity. The song nevertheless reached the top 20 of the Billboard pop charts, despite industry executives' predictions that a song containing such blatant declarations of faith would never make it to radio. The College Dropout would eventually be certified triple platinum in the US, and garnered West 10 Grammy nominations, including Album of the Year, and Best Rap Album (which it received). During this period, West also founded GOOD Music, a record label and management company that would go on to house affiliate artists and producers, such as No I.D. and John Legend. At the time, the focal point of West's production style was the use of sped-up vocal samples from soul records. However, partly because of the acclaim of The College Dropout, such sampling had been much copied by others; with that overuse, and also because West felt he had become too dependent on the technique, he decided to find a new sound.
What was the name of the single off the debut album that gave Kanye mainstream attention?
A: Jesus Walks

Problem: Please answer a question about the following article about Asphalt:
One hundred years after the fall of Constantinople in 1453, Pierre Belon described in his work Observations in 1553 that pissasphalto, a mixture of pitch and bitumen, was used in Dubrovnik for tarring of ships from where it was exported to a market place in Venice where it could be bought by anyone. An 1838 edition of Mechanics Magazine cites an early use of asphalt in France. A pamphlet dated 1621, by "a certain Monsieur d'Eyrinys, states that he had discovered the existence (of asphaltum) in large quantities in the vicinity of Neufchatel", and that he proposed to use it in a variety of ways – "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable. "He expatiates also on the excellence of this material for forming level and durable terraces" in palaces, "the notion of forming such terraces in the streets not one likely to cross the brain of a Parisian of that generation". But it was generally neglected in France until the revolution of 1830. Then, in the 1830s, there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann (BasRhin), the Parc (l'Ain) and the Puy-de-la-Poix (Puy-de-Dome)", although it could also be made artificially. One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835.
In what year did a French magazine describe the use of asphalt?
A: 1838
Problem: Please answer a question about the following article about John von Neumann:
Von Neumann made fundamental contributions to mathematical statistics. In 1941, he derived the exact distribution of the ratio of the mean square of successive differences to the sample variance for independent and identically normally distributed variables. This ratio was applied to the residuals from regression models and is commonly known as the Durbin–Watson statistic for testing the null hypothesis that the errors are serially independent against the alternative that they follow a stationary first order autoregression.
what does null hypothesis test against?
A:
alternative that they follow a stationary first order autoregression
