Problem: Sir Richard Francis Burton (; 19 March 1821 - 20 October 1890) was a British explorer, geographer, translator, writer, soldier, orientalist, cartographer, ethnologist, spy, linguist, poet, fencer, and diplomat. He was famed for his travels and explorations in Asia, Africa and the Americas, as well as his extraordinary knowledge of languages and cultures. According to one count, he spoke 29 European, Asian and African languages.

Motivated by his love of adventure, Burton got the approval of the Royal Geographical Society for an exploration of the area, and he gained permission from the board of directors of the British East India Company to take leave from the army. His seven years in India gave Burton a familiarity with the customs and behaviour of Muslims and prepared him to attempt a Hajj (pilgrimage to Mecca and, in this case, Medina). It was this journey, undertaken in 1853, which first made Burton famous. He had planned it whilst traveling disguised among the Muslims of Sindh, and had laboriously prepared for the adventure by study and practice (including undergoing the Muslim tradition of circumcision to further lower the risk of being discovered). Although Burton was certainly not the first non-Muslim European to make the Hajj (Ludovico di Varthema did this in 1503), his pilgrimage is the most famous and the best documented of the time. He adopted various disguises including that of a Pashtun to account for any oddities in speech, but he still had to demonstrate an understanding of intricate Islamic traditions, and a familiarity with the minutiae of Eastern manners and etiquette. Burton's trek to Mecca was dangerous, and his caravan was attacked by bandits (a common experience at the time). As he put it, though "... neither Koran or Sultan enjoin the death of Jew or Christian intruding within the columns that note the sanctuary limits, nothing could save a European detected by the populace, or one who after pilgrimage declared himself an unbeliever". The pilgrimage entitled him to the title of Hajji and to wear the green head wrap. Burton's own account of his journey is given in A Personal Narrative of a Pilgrimage to Al-Madinah and Meccah. When Burton returned to the British Army, he sat for examination as an Arab linguist. The examiner was Robert Lambert Playfair, who disliked Burton. As Professor George Percy Badger knew Arabic well, Playfair asked Badger to oversee the exam. Having been told that Burton could be vindictive, and wishing to avoid any animosity should Burton fail, Badger declined. Playfair conducted the tests; despite Burton's success living as an Arab, Playfair had recommended to the committee that Burton be failed. Badger later told Burton that "After looking [Burton's test] over, I [had] sent them back to [Playfair] with a note eulogising your attainments and ... remarking on the absurdity of the Bombay Committee being made to judge your proficiency inasmuch as I did not believe that any of them possessed a tithe of the knowledge of Arabic you did."

How long did he stay in Mecca?

Problem: Guy Carleton, 1st Baron Dorchester, KB (3 September 1724 - 10 November 1808), known between 1776 and 1786 as Sir Guy Carleton, was an Anglo-Irish soldier and administrator. He twice served as Governor of the Province of Quebec, from 1768 to 1778, concurrently serving as Governor General of British North America in that time, and again from 1785 to 1795. The title Baron Dorchester was created on 21 August 1786. He commanded British troops in the American War of Independence, first leading the defence of Quebec during the 1775 rebel invasion and the 1776 counteroffensive that drove the rebels from the province.

Guy Carleton was born to a Protestant military family that had lived in Ireland since the 17th century, and was one of two brothers (Thomas Carleton) that served in the British military. He also had a sister Connolly Crawford. When he was fourteen his father, Christopher Carleton died, and his mother Catherine Carleton remarried Reverend Thomas Skelton. He received a limited education. In 1742, at the age of seventeen, Carleton was commissioned as an ensign into the 25th Regiment of Foot, in which in 1745 he was promoted lieutenant. During this period he became a friend of James Wolfe; he may have served with Wolfe at the Battle of Culloden during the Jacobite rising of 1745. Two of his brothers, William and Thomas, also joined the British army. In 1740 the War of the Austrian Succession broke out in Europe. Despite British troops having been engaged on the European continent since 1742, it was not until 1747 that Carleton and his regiment were despatched to Flanders. They fought the French, but were unable to prevent the Fall of Bergen-op-Zoom, a major Dutch fortress, and the war was brought to a halt by an armistice. In 1748 the Treaty of Aix-la-Chapelle was signed and Carleton returned to Britain. He was frustrated to still only be a lieutenant, and believed his opportunities of advancement would be limited with the end of the war. In 1751 he joined the 1st Foot Guards and in 1752 was promoted to captain. His career received a major boost when he was chosen, at the suggestion of Wolfe, to act as a guide to the Duke of Richmond during a tour of the battlefields of the recent war. Richmond would become an influential patron to Carleton.
