Problem: In June 1837 Chopin visited London incognito in the company of the piano manufacturer Camille Pleyel where he played at a musical soirée at the house of English piano maker James Broadwood. On his return to Paris, his association with Sand began in earnest, and by the end of June 1838 they had become lovers. Sand, who was six years older than the composer, and who had had a series of lovers, wrote at this time: "I must say I was confused and amazed at the effect this little creature had on me ... I have still not recovered from my astonishment, and if I were a proud person I should be feeling humiliated at having been carried away ..." The two spent a miserable winter on Majorca (8 November 1838 to 13 February 1839), where, together with Sand's two children, they had journeyed in the hope of improving the health of Chopin and that of Sand's 15-year-old son Maurice, and also to escape the threats of Sand's former lover Félicien Mallefille. After discovering that the couple were not married, the deeply traditional Catholic people of Majorca became inhospitable, making accommodation difficult to find. This compelled the group to take lodgings in a former Carthusian monastery in Valldemossa, which gave little shelter from the cold winter weather.
What adjective is used to describe Frédéric and Sand's time together during the winter of 1838?

Problem: Public expenditure of the GDP was less in 2002–05 than in 1991. Public education is theoretically free and mandatory for under-16-year-olds, but in practice, expenses exist. Net primary enrollment rate was 44% in 2005, much less than the 79% in 1991. The country has universities. Education between ages six and sixteen is compulsory. Pupils who complete six years of primary school and seven years of secondary school obtain a baccalaureate. At the university, students can obtain a bachelor's degree in three years and a master's after four. Marien Ngouabi University—which offers courses in medicine, law and several other fields—is the country's only public university. Instruction at all levels is in French, and the educational system as a whole models the French system. The educational infrastructure has been seriously degraded as a result of political and economic crises. There are no seats in most classrooms, forcing children to sit on the floor. Enterprising individuals have set up private schools, but they often lack the technical knowledge and familiarity with the national curriculum to teach effectively. Families frequently enroll their children in private schools only to find they cannot make the payments.
What courses are not offered at Marien Ngouabi University?

Problem: YouTube relies on its users to flag the content of videos as inappropriate, and a YouTube employee will view a flagged video to determine whether it violates the site's terms of service. In July 2008, the Culture and Media Committee of the House of Commons of the United Kingdom stated that it was "unimpressed" with YouTube's system for policing its videos, and argued that "proactive review of content should be standard practice for sites hosting user-generated content". YouTube responded by stating:
