Input: Read this: In the Middle Ages, the site of the future palace formed part of the Manor of Ebury (also called Eia). The marshy ground was watered by the river Tyburn, which still flows below the courtyard and south wing of the palace. Where the river was fordable (at Cow Ford), the village of Eye Cross grew. Ownership of the site changed hands many times; owners included Edward the Confessor and his queen consort Edith of Wessex in late Saxon times, and, after the Norman Conquest, William the Conqueror. William gave the site to Geoffrey de Mandeville, who bequeathed it to the monks of Westminster Abbey.
Question: Which river runs underneath the palace?

Input: Read this: In 2000, Dell announced that it would lease 80,000 square feet (7,400 m2) of space in the Las Cimas office complex in unincorporated Travis County, Texas, between Austin and West Lake Hills, to house the company's executive offices and corporate headquarters. 100 senior executives were scheduled to work in the building by the end of 2000. In January 2001, the company leased the space in Las Cimas 2, located along Loop 360. Las Cimas 2 housed Dell's executives, the investment operations, and some corporate functions. Dell also had an option for 138,000 square feet (12,800 m2) of space in Las Cimas 3. After a slowdown in business required reducing employees and production capacity, Dell decided to sublease its offices in two buildings in the Las Cimas office complex. In 2002 Dell announced that it planned to sublease its space to another tenant; the company planned to move its headquarters back to Round Rock once a tenant was secured. By 2003, Dell moved its headquarters back to Round Rock. It leased all of Las Cimas I and II, with a total of 312,000 square feet (29,000 m2), for about a seven-year period after 2003. By that year roughly 100,000 square feet (9,300 m2) of that space was absorbed by new subtenants.

Input: Read this: When a USB device is first connected to a USB host, the USB device enumeration process is started. The enumeration starts by sending a reset signal to the USB device. The data rate of the USB device is determined during the reset signaling. After reset, the USB device's information is read by the host and the device is assigned a unique 7-bit address. If the device is supported by the host, the device drivers needed for communicating with the device are loaded and the device is set to a configured state. If the USB host is restarted, the enumeration process is repeated for all connected devices.
Question: When is the device assigned a unique 7-bit address?

Output: After reset
