In 1344, Momchil, the independent Bulgarian ruler of the Rhodope and Aegean regions, whose army grew to 2,000 men, took an important role in the Byzantine civil war. While at first he supported John Kantakouzenos, from the spring of 1344 Momchil reneged, provoked by the aggression of the Ottoman allies. In June he defeated the Ottoman fleet near the Portogalos bay. According to sources, at night the Bulgarian ruler sent boats to burn the anchored Ottoman ships and soon after he defeated the army of Kantakouzenos at Mosynopolis. Probably the first local ruler to become aware of the impending Ottoman threat, Momchil unsuccessfully pleaded with the emperors of Bulgaria and Byzantium for help. Even though his troops continued the resistance in the Eastern Rhodopes, in May 1345 the Turks led by Umur Beg marched from Asia Minor and devastated Bulgarian territories driving away people and livestock. Soon after, on 7 July 1345, Ottoman forces under Umur Beg defeated Momchil's army in the battle of Peritor near his capital Xanthi. Sources attest that the independent ruler perished in the battle without leaving asuccessor, and with little political will or leadership left to counter the Ottoman invasion.

Which two groups experienced defeat in 1345?
A: Bulgarian territories

Johann Bayer used the Greek letters Alpha to Eta to label the most prominent eight stars in the constellation, designating two stars as Delta (named Delta1 and Delta2). John Flamsteed numbered fourteen stars, discerning a third star he named Delta3; his star 12 Canis Minoris was not found subsequently. In Bayers 1603 work Uranometria, Procyon is located on the dogs belly, and Gomeisa on its neck. Gamma Canis Minoris, Epsilon Canis Minoris and Eta Canis Minoris lie nearby, marking the dogs neck, crown and chest respectively. Although it has an apparent magnitude of 4.34, Gamma Canis Minoris is an orange stellar classification giant star of spectral class K3-III C, which lies  away. Its colour is obvious when seen through binoculars. It is a multiple system, consisting of the  spectroscopic binary Gamma A and three optical companions, Gamma B, magnitude 13; Gamma C, magnitude 12; and Gamma D, magnitude 10. The two components of Gamma A orbit each other every 389.2 days, with an eccentric orbit that takes their separation between 2.3 and 1.4 astronomical units (AU). Epsilon Canis Minoris is a yellow bright giant of spectral class G6.5IIb of magnitude of 4.99. It lies  from Earth, with 13 times the diameter and 750 times the luminosity of the Sun. Eta Canis Minoris is a giant of spectral class F0III of magnitude 5.24, which has a yellowish hue when viewed through binoculars as well as a faint companion of magnitude 11.1. Located 4 arcseconds from the primary, the companion star is actually around 440 AU from the main star and takes around 5000 years to orbit it.

What is 13 times the diameter of the sun?
A: Epsilon Canis Minoris

The share of value added by the cotton textile industry in Britain was 2.6% in 1760, 17% in 1801 and 22.4% in 1831.  Value added by the British woollen industry was 14.1% in 1801.  Cotton factories in Britain numbered approximately 900 in 1797.  In 1760 approximately one-third of cotton cloth manufactured in Britain was exported, rising to two-thirds by 1800.  In 1781 cotton spun amounted to 5.1 million pounds, which increased to 56 million pounds by 1800.  In 1800 less than 0.1% of world cotton cloth was produced on machinery invented in Britain.  In 1788 there were 50,000 spindles in Britain, rising to 7 million over the next 30 years.

How many more percent was the value added by the cotton textile industry in 1831 compared to 1801?
A:
5.4
