Problem: A USB packet's end, called EOP (end-of-packet), is indicated by the transmitter driving 2 bit times of SE0 (D+ and D both below max.) and 1 bit time of J state. After this, the transmitter ceases to drive the D+/D lines and the aforementioned pull up resistors hold it in the J (idle) state. Sometimes skew due to hubs can add as much as one bit time before the SE0 of the end of packet. This extra bit can also result in a "bit stuff violation" if the six bits before it in the CRC are 1s. This bit should be ignored by receiver.
What is a USB packet's end called?

Answer: EOP (end-of-packet)

Problem: Strasbourg is situated on the eastern border of France with Germany. This border is formed by the River Rhine, which also forms the eastern border of the modern city, facing across the river to the German town Kehl. The historic core of Strasbourg however lies on the Grande Ile in the River Ill, which here flows parallel to, and roughly 4 kilometres (2.5 mi) from, the Rhine. The natural courses of the two rivers eventually join some distance downstream of Strasbourg, although several artificial waterways now connect them within the city.
How far downstream from Strasbourg does the River Rhine and River ILL meet?

Answer: unanswerable

Problem: From the end of the 1980s to the early 1990s, the FBI reassigned more than 300 agents from foreign counter-intelligence duties to violent crime, and made violent crime the sixth national priority. With reduced cuts to other well-established departments, and because terrorism was no longer considered a threat after the end of the Cold War, the FBI assisted local and state police forces in tracking fugitives who had crossed state lines, which is a federal offense. The FBI Laboratory helped develop DNA testing, continuing its pioneering role in identification that began with its fingerprinting system in 1924.
What priority were violent crimes in the 1990s, according to the FBI?

Answer:
sixth national priority
