Problem: The Gregorian reform contained two parts: a reform of the Julian calendar as used prior to Pope Gregory XIII's time and a reform of the lunar cycle used by the Church, with the Julian calendar, to calculate the date of Easter. The reform was a modification of a proposal made by Aloysius Lilius. His proposal included reducing the number of leap years in four centuries from 100 to 97, by making 3 out of 4 centurial years common instead of leap years. Lilius also produced an original and practical scheme for adjusting the epacts of the moon when calculating the annual date of Easter, solving a long-standing obstacle to calendar reform.
What was the second reform of the calendar?
The answer is the following: lunar cycle

Problem: Relocating his court from Jianzhou to Liaodong provided Nurhachi access to more resources; it also brought him in close contact with the Khorchin Mongol domains on the plains of Mongolia. Although by this time the once-united Mongol nation had long since fragmented into individual and hostile tribes, these tribes still presented a serious security threat to the Ming borders. Nurhachi's policy towards the Khorchins was to seek their friendship and cooperation against the Ming, securing his western border from a powerful potential enemy.
Where did Nurhachi move his court from?
The answer is the following: Jianzhou

Problem: While highly effective, the requirement for injection limited the use of norepinephrine[clarification needed] and orally active derivatives were sought. A structurally similar compound, ephedrine, was identified by Japanese chemists in the Ma Huang plant and marketed by Eli Lilly as an oral treatment for asthma. Following the work of Henry Dale and George Barger at Burroughs-Wellcome, academic chemist Gordon Alles synthesized amphetamine and tested it in asthma patients in 1929. The drug proved to have only modest anti-asthma effects, but produced sensations of exhilaration and palpitations. Amphetamine was developed by Smith, Kline and French as a nasal decongestant under the trade name Benzedrine Inhaler. Amphetamine was eventually developed for the treatment of narcolepsy, post-encepheletic parkinsonism, and mood elevation in depression and other psychiatric indications. It received approval as a New and Nonofficial Remedy from the American Medical Association for these uses in 1937 and remained in common use for depression until the development of tricyclic antidepressants in the 1960s.
What were some uses for Amphetamine?
The answer is the following: narcolepsy, post-encepheletic parkinsonism, and mood elevation in depression and other psychiatric indications

Problem: Neoclassical architecture was introduced in Malta in the late 18th century, during the final years of Hospitaller rule. Early examples include the Bibliotheca (1786), the De Rohan Arch (1798) and the Hompesch Gate (1801). However, neoclassical architecture only became popular in Malta following the establishment of British rule in the early 19th century. In 1814, a neoclassical portico decorated with the British coat of arms was added to the Main Guard building so as to serve as a symbol of British Malta. Other 19th century neoclassical buildings include RNH Bighi (1832), St Paul's Pro-Cathedral (1844), the Rotunda of Mosta (1860) and the now destroyed Royal Opera House (1866).
When was Malta introduced to neoclassical architecture?
The answer is the following:
late 18th century
