Menopause

Menopause, also known as the climacteric, is the time in most women's lives when menstrual periods stop permanently, and they are no longer able to bear children.[2][8] Menopause typically occurs between 49 and 52 years of age.[3] Medical professionals often define menopause as having occurred when a woman has not had any vaginal bleeding for a year.[4] It may also be defined by a decrease in hormone production by the ovaries.[9] In those who have had surgery to remove their uterus but still have ovaries, menopause may be viewed to have occurred at the time of the surgery or when their hormone levels fell.[9] Following the removal of the uterus, symptoms typically occur earlier, at an average of 45 years of age.[10]

Question: When does Menopause start?

Alfred the Great

Alfred died on 26 October 899 at the age of 50 or 51.[134] How he died is unknown, although he suffered throughout his life with a painful and unpleasant illness. His biographer Asser gave a detailed description of Alfred's symptoms and this has allowed modern doctors to provide a possible diagnosis. It is thought that he had either Crohn's disease or haemorrhoidal disease.[8][135] His grandson King Eadred seems to have suffered from a similar illness.[136][lower-alpha 8]

Gallic Wars

The Gallic Wars were a series of military campaigns waged by the Roman proconsul Julius Caesar against several Gallic tribes. Rome's war against the Gallic tribes lasted from 58 BC to 50 BC and culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul (mainly present-day France and Belgium). While militarily just as strong as the Romans, the internal division between the Gallic tribes helped ease victory for Caesar, and Vercingetorix's attempt to unite the Gauls against Roman invasion came too late.[6][7] The wars paved the way for Julius Caesar to become the sole ruler of the Roman Republic.

Question: When were the Gallic Wars?
Answer: from 58 BC to 50 BC
Guantanamo Bay Naval Base

Guantanamo Bay Naval Base (Spanish: Base Naval de la Bahía de Guantánamo), officially known as Naval Station Guantanamo Bay or NSGB (also called GTMO because of the abbreviation of Guantanamo or Gitmo because of the common pronunciation of this word by the U.S. military[1]), is a United States military base and detention camp located on 120 square kilometers (45sqmi) of land and water at Guantánamo Bay, Cuba, which the U.S. leased for use as a coaling station and naval base in 1903. The lease was $2,000 in gold per year until 1934, when the payment was set to match the value in gold in dollars;[2] in 1974, the yearly lease was set to $4,085.[3] The base is on the shore of Guantánamo Bay at the southeastern end of Cuba. It is the oldest overseas U.S. Naval Base.[4] Since the Cuban Revolution of 1959, the Cuban government has consistently protested against the U.S. presence on Cuban soil and called it illegal under international law, alleging that the base was imposed on Cuba by force.

Question: What is the oldest overseas U.S. military base?
Answer: Guantanamo Bay Naval Base
David (Michelangelo)

The history of the statue begins before Michelangelo's work on it from 1501 to 1504.[3] Prior to Michelangelo's involvement, the Overseers of the Office of Works of Florence Cathedral, consisting mostly of members of the influential woolen cloth guild, the Arte della Lana, had plans to commission a series of twelve large Old Testament sculptures for the buttresses of the cathedral.[4] In 1410 Donatello made the first of the statues, a figure of Joshua in terracotta. A figure of Hercules, also in terracotta, was commissioned from the Florentine sculptor Agostino di Duccio in 1463 and was made perhaps under Donatello's direction.[5] Eager to continue their project, in 1464, the Operai contracted Agostino to create a sculpture of David. A block of marble was provided from a quarry in Carrara, a town in the Apuan Alps in northern Tuscany. Agostino only got as far as beginning to shape the legs, feet and the torso, roughing out some drapery and probably gouging a hole between the legs. His association with the project ceased, for reasons unknown, with the death of Donatello in 1466, and ten years later Antonio Rossellino was commissioned to take up where Agostino had left off.

Question: When did Michelangelo create the David?
Answer: 1501 to 1504
Nazi Party

Hitler's first DAP speech was held in the Hofbräukeller on 16 October 1919. He was the second speaker of the evening, and spoke to 111 people.[43] Hitler later declared that this was when he realised he could really "make a good speech".[30] At first, Hitler spoke only to relatively small groups, but his considerable oratory and propaganda skills were appreciated by the party leadership. With the support of Anton Drexler, Hitler became chief of propaganda for the party in early 1920.[44] Hitler began to make the party more public, and organised its biggest meeting yet of 2,000 people on 24 February 1920 in the Staatliches Hofbräuhaus in München. Such was the significance of this particular move in publicity that Karl Harrer resigned from the party in disagreement.[45] It was in this speech that Hitler enunciated the twenty-five points of the German Workers' Party manifesto that had been drawn up by Drexler, Feder and himself.[46] Through these points he gave the organisation a much bolder stratagem[44] with a clear foreign policy (abrogation of the Treaty of Versailles, a Greater Germany, Eastern expansion and exclusion of Jews from citizenship) and among his specific points were: confiscation of war profits, abolition of unearned incomes, the State to share profits of land and land for national needs to be taken away without compensation.[47] In general, the manifesto was antisemitic, anti-capitalist, anti-democratic, anti-Marxist and anti-liberal.[48] To increase its appeal to larger segments of the population, on the same day as Hitler's Hofbräuhaus speech on 24 February 1920, the DAP changed its name to the Nationalsozialistische Deutsche Arbeiterpartei ("National Socialist German Workers' Party", or Nazi Party).[49][50] The word "Socialist" was added by the party's executive committee, over Hitler's objections, in order to help appeal to left-wing workers.[51]

Question: When was the Nazi party founded?
Answer: 24 February 1920

Llantrisant and Taff Vale Junction Railway

Thomas Powell had extensive colliery interests in Monmouthshire and Glamorganshire, and he needed to get a transport link to pits he owned at Llantwit Fardre. Failing to generate interest elsewhere, he determined to build a railway himself to the Glamorganshire Canal at Maesmawr from Llantwit Fardre. This was known as the Dihewyd Railway or the Llantwit Fardre Railway. It was completed by 28 December 1843 and a connection to the Taff Vale Railway was opened on 25 April 1844, when a train of Powell's coal was taken to Cardiff. His line climbed out of Maesmawr on a 297-yard self-acting incline at a gradient of 1 in 6.6. The line was later extended to Ystradbarwig colliery.[3]

Battle of Morval

The battle was a considerable Anglo-French victory and as no tanks were used in the initial Fourth Army attack, a continuous creeping barrage was maintained.[53] The objective of one German trench system, the original third line, which was less well-developed than the German defences on 15 September, was subjected to 40 percent greater weight of shellfire. Rainfall from 16–22 September and the tempo of attacks, made it difficult for the Germans to improve their defences. Cavalry were even able to seize some tactical objectives and infantry kept well up to the creeping bombardment, limiting losses to 5,000 men in the ten British divisions engaged.[54][55] French attacks in the south beyond Combles, made little progress against massed German artillery fire and Fayolle concluded that an extensive artillery preparation would be needed, to resuming the attack around 7–8 October.[56]

Question: How many British troops died in the Battle of Morval?
Answer: 5,000
