Student A:Passage: Urbanisation began in 1902, when a railroad linking Los Angeles and Salt Lake City attracted many farmers to the area, and fresh water was piped into the settlement. In 1911, the city was incorporated as part of Clark County. In 1931 work started on the Boulder Dam (now the Hoover Dam), bringing a huge influx of young male workers, for whom theatres and casinos were built, largely by the Mafia. Electricity from the dam also enabled the building of many new hotels along the Strip. The arrival of Howard Hughes in 1966 did much to offset mob influence, and helped turn Las Vegas into more of a family tourist centre, now classified as a Megaresort.

Student A:Passage: Texas has no laws regarding possession of any firearm regardless of age, without felony convictions; all existing restrictions in State law mirror Federal law. A person of any age, except certain Felons, can possess a firearm such as at a firing range. Texas and Federal law only regulate the ownership of all firearms to 18 years of age or older, and regulate the transfer of handguns to 21 years or older by FFL dealers. However, a private citizen may sell, gift, lease etc. a handgun to anyone over 18 who is not Felon. NFA weapons are also only subject to Federal restrictions; no State regulations exist. Municipal and county ordinances on possession and carry are generally overridden (preempted) due to the wording of the Texas Constitution, which gives the Texas Legislature (and it alone) the power to "regulate the wearing of arms, with a view to prevent crime". Penal Code Section 1.08 also prohibits local jurisdictions from enacting or enforcing any law that conflicts with State statute. Local ordinances restricting discharge of a firearm are generally allowed as State law has little or no specification thereof, but such restrictions do not preempt State law concerning justification of use of force and deadly force.
