Context and question: The stress of the war had taken its toll on the King's health, exacerbated by his heavy smoking and subsequent development of lung cancer among other ailments, including arteriosclerosis and thromboangiitis obliterans. A planned tour of Australia and New Zealand was postponed after the King suffered an arterial blockage in his right leg, which threatened the loss of the leg and was treated with a right lumbar sympathectomy in March 1949. His elder daughter Elizabeth, the heir presumptive, took on more royal duties as her father's health deteriorated. The delayed tour was re-organised, with Elizabeth and her husband, the Duke of Edinburgh, taking the place of the King and Queen. The King was well enough to open the Festival of Britain in May 1951, but on 23 September 1951, his left lung was removed by Clement Price Thomas after a malignant tumour was found. In October 1951, Princess Elizabeth and the Duke of Edinburgh went on a month-long tour of Canada; the trip had been delayed for a week due to the King's illness. At the State Opening of Parliament in November, the King's speech from the throne was read for him by the Lord Chancellor, Lord Simonds. His Christmas broadcast of 1951 was recorded in sections, and then edited together.
In what year was Lord Simonds made the Lord Chancellor?

Context and question: The gut is generally an almost straight tube supported by the mesenteries (vertical partitions within segments), and ends with the anus on the underside of the pygidium. However, in members of the tube-dwelling family Siboglinidae the gut is blocked by a swollen lining that houses symbiotic bacteria, which can make up 15% of the worms' total weight. The bacteria convert inorganic matter – such as hydrogen sulfide and carbon dioxide from hydrothermal vents, or methane from seeps – to organic matter that feeds themselves and their hosts, while the worms extend their palps into the gas flows to absorb the gases needed by the bacteria.
What gases come from seeps?
Answer: methane
Context and question: Yazid died while the siege was still in progress, and the Umayyad army returned to Damascus, leaving Ibn al-Zubayr in control of Mecca. Yazid's son Muawiya II (683–84) initially succeeded him but seems to have never been recognized as caliph outside of Syria. Two factions developed within Syria: the Confederation of Qays, who supported Ibn al-Zubayr, and the Quda'a, who supported Marwan, a descendant of Umayya via Wa'il ibn Umayyah. The partisans of Marwan triumphed at a battle at Marj Rahit, near Damascus, in 684, and Marwan became caliph shortly thereafter.
Who was a descendant of Marwan?
