[Q]: Elizabeth's only sibling, Princess Margaret, was born in 1930. The two princesses were educated at home under the supervision of their mother and their governess, Marion Crawford, who was casually known as "Crawfie". Lessons concentrated on history, language, literature and music. Crawford published a biography of Elizabeth and Margaret's childhood years entitled The Little Princesses in 1950, much to the dismay of the royal family. The book describes Elizabeth's love of horses and dogs, her orderliness, and her attitude of responsibility. Others echoed such observations: Winston Churchill described Elizabeth when she was two as "a character. She has an air of authority and reflectiveness astonishing in an infant." Her cousin Margaret Rhodes described her as "a jolly little girl, but fundamentally sensible and well-behaved".

[Q]: As the school suffered reduced income while still under construction, the completion and further development of the school has since depended to some extent on wealthy benefactors. Building resumed when Roger Lupton was Provost, around 1517. His name is borne by the big gate-house in the west range of the cloisters, fronting School Yard, perhaps the most famous image of the school. This range includes the important interiors of the Parlour, Election Hall, and Election Chamber, where most of the 18th century "leaving portraits" are kept.
[A]: Around what year did construction continue after a period of financial struggle?


[Q]: For those with severe persistent asthma not controlled by inhaled corticosteroids and LABAs, bronchial thermoplasty may be an option. It involves the delivery of controlled thermal energy to the airway wall during a series of bronchoscopies. While it may increase exacerbation frequency in the first few months it appears to decrease the subsequent rate. Effects beyond one year are unknown. Evidence suggests that sublingual immunotherapy in those with both allergic rhinitis and asthma improve outcomes.
[A]:
What type of person would use bronchial thermoplasty as an option?
