After the setback at Aspern-Essling, Napoleon took more than six weeks in planning and preparing for contingencies before he made another attempt at crossing the Danube. From 30 June to the early days of July, the French recrossed the Danube in strength, with more than 180,000 troops marching across the Marchfeld towards the Austrians. Charles received the French with 150,000 of his own men. In the ensuing Battle of Wagram, which also lasted two days, Napoleon commanded his forces in what was the largest battle of his career up until then. Neither side made much progress on 5 July, but the 6th produced a definitive outcome. Both sides launched major assaults on their flanks. Austrian attacks against the French left wing looked dangerous initially, but they were all beaten back. Meanwhile, a steady French attack against the Austrian left wing eventually compromised the entire position for Charles. Napoleon finished off the battle with a concentrated central thrust that punctured a hole in the Austrian army and forced Charles to retreat. Austrian losses were very heavy, reaching well over 40,000 casualties. The French were too exhausted to pursue the Austrians immediately, but Napoleon eventually caught up with Charles at Znaim and the latter signed an armistice on 12 July.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How long did the Battle of Wagram last?
Ah, so.. two days

On 29 May 1842, Victoria was riding in a carriage along The Mall, London, when John Francis aimed a pistol at her but the gun did not fire; he escaped. The following day, Victoria drove the same route, though faster and with a greater escort, in a deliberate attempt to provoke Francis to take a second aim and catch him in the act. As expected, Francis shot at her, but he was seized by plain-clothes policemen, and convicted of high treason. On 3 July, two days after Francis's death sentence was commuted to transportation for life, John William Bean also tried to fire a pistol at the Queen, but it was loaded only with paper and tobacco and had too little charge. Edward Oxford felt that the attempts were encouraged by his acquittal in 1840. Bean was sentenced to 18 months in jail. In a similar attack in 1849, unemployed Irishman William Hamilton fired a powder-filled pistol at Victoria's carriage as it passed along Constitution Hill, London. In 1850, the Queen did sustain injury when she was assaulted by a possibly insane ex-army officer, Robert Pate. As Victoria was riding in a carriage, Pate struck her with his cane, crushing her bonnet and bruising her forehead. Both Hamilton and Pate were sentenced to seven years' transportation.

Ah, so.. William Hamilton

USB device communication is based on pipes (logical channels). A pipe is a connection from the host controller to a logical entity, found on a device, and named an endpoint. Because pipes correspond 1-to-1 to endpoints, the terms are sometimes used interchangeably. A USB device could have up to 32 endpoints (16 IN, 16 OUT), though it's rare to have so many. An endpoint is defined and numbered by the device during initialization (the period after physical connection called "enumeration") and so is relatively permanent, whereas a pipe may be opened and closed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many endpoints can a USB device have?
Ah, so..
up to 32 endpoints
