Question: During the Cambrian period, Gondwana had a mild climate. West Antarctica was partially in the Northern Hemisphere, and during this period large amounts of sandstones, limestones and shales were deposited. East Antarctica was at the equator, where sea floor invertebrates and trilobites flourished in the tropical seas. By the start of the Devonian period (416 Ma), Gondwana was in more southern latitudes and the climate was cooler, though fossils of land plants are known from this time. Sand and silts were laid down in what is now the Ellsworth, Horlick and Pensacola Mountains. Glaciation began at the end of the Devonian period (360 Ma), as Gondwana became centered on the South Pole and the climate cooled, though flora remained. During the Permian period, the land became dominated by seed plants such as Glossopteris, a pteridosperm which grew in swamps. Over time these swamps became deposits of coal in the Transantarctic Mountains. Towards the end of the Permian period, continued warming led to a dry, hot climate over much of Gondwana.
Is there an answer to this question: In what hemisphere did west Antarctica share during the Cambrian?

Answer: Northern


Question: The Federation of International Gymnastics (FIG) was founded in Liege in 1881. By the end of the nineteenth century, men's gymnastics competition was popular enough to be included in the first "modern" Olympic Games in 1896. From then on until the early 1950s, both national and international competitions involved a changing variety of exercises gathered under the rubric, gymnastics, that would seem strange to today's audiences and that included for example, synchronized team floor calisthenics, rope climbing, high jumping, running, and horizontal ladder. During the 1920s, women organized and participated in gymnastics events. The first women's Olympic competition was primitive, only involving synchronized calisthenics and track and field. These games were held in 1928, in Amsterdam.

Question: From 7 September 1940, one year into the war, London was bombed by the Luftwaffe for 57 consecutive nights. More than one million London houses were destroyed or damaged and more than 40,000 civilians were killed, almost half of them in London. Ports and industrial centres outside London were also attacked. The main Atlantic sea port of Liverpool was bombed, causing nearly 4,000 deaths within the Merseyside area during the war. The North Sea port of Hull, a convenient and easily found target or secondary target for bombers unable to locate their primary targets, was subjected to 86 raids in the Hull Blitz during the war, with a conservative estimate of 1,200 civilians killed and 95 percent of its housing stock destroyed or damaged. Other ports including Bristol, Cardiff, Portsmouth, Plymouth, Southampton and Swansea were also bombed, as were the industrial cities of Birmingham, Belfast, Coventry, Glasgow, Manchester and Sheffield. Birmingham and Coventry were chosen because of the Spitfire and tank factories in Birmingham and the many munitions factories in Coventry. The city centre of Coventry was almost destroyed, as was Coventry Cathedral.
Is there an answer to this question: How many people were killed in Liverpool?

Answer: nearly 4,000 deaths


Question: 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.
Is there an answer to this question: How many parts did the Gregorian calendar reform have?

Answer:
two parts
