TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What did the supercapacitors improve?, Context: Last but not least the electric double-layer capacitor (now Supercapacitors) were invented. In 1957 H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors. Because the double layer mechanism was not known by him at the time, he wrote in the patent: "It is not known exactly what is taking place in the component if it is used for energy storage, but it leads to an extremely high capacity.".

SOLUTION: electrolytic capacitor

PROBLEM: What term did the UK used to use to describe a period of time during someone's school aged years?, Context: Colloquially, the term university may be used to describe a phase in one's life: "When I was at university..." (in the United States and Ireland, college is often used instead: "When I was in college..."). In Australia, Canada, New Zealand, the United Kingdom, Nigeria, the Netherlands, Spain and the German-speaking countries university is often contracted to uni. In Ghana, New Zealand and in South Africa it is sometimes called "varsity" (although this has become uncommon in New Zealand in recent years). "Varsity" was also common usage in the UK in the 19th century.[citation needed] "Varsity" is still in common usage in Scotland.

SOLUTION: Varsity

PROBLEM: What was the purpose of Microsoft's pop-up stores?, Context: Microsoft began an advertising campaign centered around Windows 8 and its Surface tablet in October 2012, starting with its first television advertisement premiering on October 14, 2012. Microsoft's advertising budget of US$1.5–1.8 billion was significantly larger than the US$200 million campaign used to promote Windows 95. As part of its campaign, Microsoft set up 34 pop-up stores inside malls (primarily focusing on Surface), provided training for retail employees in partnership with Intel, and collaborated with the electronics store chain Best Buy to design expanded spaces to showcase devices. In an effort to make retail displays of Windows 8 devices more "personal", Microsoft also developed a character known in English-speaking markets as "Allison Brown", whose fictional profile (including personal photos, contacts, and emails) is also featured on demonstration units of Windows 8 devices.

SOLUTION:
retail displays of Windows 8 devices
