By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What commodity was Houston known for in 1860? 
Ah, so.. cotton

Frequencies for COMPASS are allocated in four bands: E1, E2, E5B, and E6 and overlap with Galileo. The fact of overlapping could be convenient from the point of view of the receiver design, but on the other hand raises the issues of inter-system interference, especially within E1 and E2 bands, which are allocated for Galileo's publicly regulated service. However, under International Telecommunication Union (ITU) policies, the first nation to start broadcasting in a specific frequency will have priority to that frequency, and any subsequent users will be required to obtain permission prior to using that frequency, and otherwise ensure that their broadcasts do not interfere with the original nation's broadcasts. It now appears that Chinese COMPASS satellites will start transmitting in the E1, E2, E5B, and E6 bands before Europe's Galileo satellites and thus have primary rights to these frequency ranges.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are the four bands of frequencies used by the COMPASS system called?
Ah, so.. E1, E2, E5B, and E6

The Syriac term Nasrani (Nazarene) has also been attached to the Saint Thomas Christians of Kerala, India. In the Indian subcontinent, Christians call themselves Isaai (Hindi: ईसाई, Urdu: عیسائی‎), and are also known by this term to adherents of other religions.

If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do people in Nasrani call Jesus?
Ah, so..
