[EX Q]: What Latin word means an assualt, or a rushing upon?, Context: By the 9th century, Catalan had evolved from Vulgar Latin on both sides of the eastern end of the Pyrenees, as well as the territories of the Roman province of Hispania Tarraconensis to the south. From the 8th century onwards the Catalan counts extended their territory southwards and westwards at the expense of the Muslims, bringing their language with them. This process was given definitive impetus with the separation of the County of Barcelona from the Carolingian Empire in 988.

[EX Q]: What was West's first chart topping single?, Context: 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.
