PROBLEM: Passage: Chopin made his last public appearance on a concert platform at London's Guildhall on 16 November 1848, when, in a final patriotic gesture, he played for the benefit of Polish refugees. By this time he was very seriously ill, weighing under 99 pounds (i.e. less than 45 kg), and his doctors were aware that his sickness was at a terminal stage. Question: Who were the beneficiaries of his last public concert?

SOLUTION: Polish refugees.

PROBLEM: Passage: In the later Imperial era, the burial and commemorative practises of Christian and non-Christians overlapped. Tombs were shared by Christian and non-Christian family members, and the traditional funeral rites and feast of novemdialis found a part-match in the Christian Constitutio Apostolica. The customary offers of wine and food to the dead continued; St Augustine (following St Ambrose) feared that this invited the "drunken" practices of Parentalia but commended funeral feasts as a Christian opportunity to give alms of food to the poor. Christians attended Parentalia and its accompanying Feralia and Caristia in sufficient numbers for the Council of Tours to forbid them in AD 567. Other funerary and commemorative practices were very different. Traditional Roman practice spurned the corpse as a ritual pollution; inscriptions noted the day of birth and duration of life. The Christian Church fostered the veneration of saintly relics, and inscriptions marked the day of death as a transition to "new life". Question: What did St Augustine believe that funeral feasts gave an opportunity for?

SOLUTION: alms of food

PROBLEM: Passage: During the Soviet period, the policy toward the languages of the various other ethnic groups fluctuated in practice. Though each of the constituent republics had its own official language, the unifying role and superior status was reserved for Russian, although it was declared the official language only in 1990. Following the break-up of the USSR in 1991, several of the newly independent states have encouraged their native languages, which has partly reversed the privileged status of Russian, though its role as the language of post-Soviet national discourse throughout the region has continued. Question: When did the USSR dissolve?

SOLUTION:
1991
