question: Des Vœux became stipendiary magistrate and superintendent of rivers and creeks in British Guiana from 1863 to 1869, where he championed native causes. He reorganised and codified old French system of law when he was the Administrator and Colonial Secretary of St. Lucia between 1869 and 1880. Afterwards, Des Vœux was appointed Governor of Fiji and High Commissioner Western Pacific from 1880 to 1885. He was appointed Governor of Newfoundland from 1886-1887. Based on his experience in British Guiana where he witnessed many instances of cruel and unjust treatment of indentured servants by plantation owners and managers, des Vœux wrote a 10,000-word report in 1869 to Lord Granville, the Secretary of State for the Colonies in which he detailed many abuses. When the contents of the report were published, there was a great outcry and a commission of inquiry was appointed, the Commission of Inquiry into the Treatment of Immigrants. Des Vœux gave testimony before the commission in Georgetown and its report led to many improvements in the workers' treatment.

question: The Kerma culture was an early civilization which flourished from around 2500 BC to about 1600 BC in Nubia, present day Sudan, centered at Kerma. It seems to have been one of a number of Sudanese states during the Middle Kingdom period of Ancient Egypt. In its latest phase, lasting from about 1700-1500 BC, it absorbed the Sudanese kingdom of Sai and became a sizable, populous empire rivaling Egypt. Around 1500 BC, it was absorbed into the Egyptian Empire, but rebellions continued for centuries. By the 11th century BC, the more 'Egyptianized' Kingdom of Kush emerged, apparently from Kerma, and regained the region's independence from Egypt.
Answer this question: Around how many centuries did the Kerma culture exist?
answer: 9

question: In the next 4 years, the Saudi ruler was preoccupied with consolidation of his domain, undertaking several campaigns in new regions of Arabia, while keeping the Hejazi frontier quiet. Jabal Shammar was annexed in 1920-21, while Kuwait was defeated in 1922, defining the border with Iraq and Transjordan through the Uqair protocol of 1922, while simultaneously conquering Asir in south Arabia. By early 1923, Ibn Saud decided to take over Hejaz, but was unsure over British position. The worsening relations between England and Hashemite rulers and the proclamation of Sharif Husayn as Caliph, finally made Ibn Saud to undertake the campaign, entusiasthically supported by the religiously insigted Ikhwan, who had hoped to take over the holy sites of Islam. The preliminary attack on Taif came in September 1924, beginning the Saudi conquest, which would be complete on December 1925.
Answer this question: How many months did the Saudi conquest take?
answer:
15
