Problem: Tuberculosis (TB) is an infectious disease usually caused by the bacterium Mycobacterium tuberculosis (MTB). Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections do not have symptoms, known as latent tuberculosis. About 10% of latent infections progress to active disease which, if left untreated, kills about half of those infected. The classic symptoms of active TB are a chronic cough with blood-containing sputum, fever, night sweats, and weight loss. The historical term "consumption" came about due to the weight loss. Infection of other organs can cause a wide range of symptoms.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
With the defeat of Marshal Bazaine's Army of the Rhine at Gravelotte, the French were forced to retire to Metz, where they were besieged by over 150,000 Prussian troops of the First and Second Armies. Napoleon III and MacMahon formed the new French Army of Châlons, to march on to Metz to rescue Bazaine. Napoleon III personally led the army with Marshal MacMahon in attendance. The Army of Châlons marched northeast towards the Belgian border to avoid the Prussians before striking south to link up with Bazaine. The Prussians, under the command of Field Marshal Count Helmuth von Moltke, took advantage of this maneuver to catch the French in a pincer grip. He left the Prussian First and Second Armies besieging Metz, except three corps detached to form the Army of the Meuse under the Crown Prince of Saxony. With this army and the Prussian Third Army, Moltke marched northward and caught up with the French at Beaumont on 30 August. After a sharp fight in which they lost 5,000 men and 40 cannons, the French withdrew toward Sedan. Having reformed in the town, the Army of Châlons was immediately isolated by the converging Prussian armies. Napoleon III ordered the army to break out of the encirclement immediately. With MacMahon wounded on the previous day, General Auguste Ducrot took command of the French troops in the field.
Who formed the new French Army of Chalons?
A: Napoleon III and MacMahon

At the time of her accession, the government was led by the Whig prime minister Lord Melbourne, who at once became a powerful influence on the politically inexperienced Queen, who relied on him for advice. Charles Greville supposed that the widowed and childless Melbourne was "passionately fond of her as he might be of his daughter if he had one", and Victoria probably saw him as a father figure. Her coronation took place on 28 June 1838 at Westminster Abbey. Over 400,000 visitors came to London for the celebrations. She became the first sovereign to take up residence at Buckingham Palace and inherited the revenues of the duchies of Lancaster and Cornwall as well as being granted a civil list allowance of £385,000 per year. Financially prudent, she paid off her father's debts.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many people visited London for the Coronation of Queen Victoria? 
Ah, so..
400,000
