Q: Although the federal government does not normally regulate air guns, some state and local governments do; the Law Center to Prevent Gun Violence has compiled a list of states and selected municipalities that regulate air guns, finding that 23 states and the District of Columbia regulate air guns to some degree. Two states (New Jersey and Rhode Island) define all non-powder guns as firearms; one state (Illinois) defines certain high-power and/or large calibre non-powder guns as firearms; three states (Connecticut, Delaware and North Dakota) define non-powder guns as dangerous weapons (but not firearms). The remaining states which regulate air guns impose age restrictions on possession, use, or transfer of non-powder guns, and/or explicitly regulate possession of non-powder guns on school grounds.

Q: The ''Argentine National Anthem'' (Spanish: Himno Nacional Argentino) is the national anthem of Argentina. Its lyrics were written by the Buenos Aires-born politician Vicente Lopez y Planes and the music was composed by the Spanish musician Blas Parera. The work was adopted as the sole official song on May 11, 1813, three years after the May Revolution; May 11 is therefore now Anthem Day in Argentina.
Can we conclude that are there any words to the argentine national anthem?
A: yes

Q: It typically lacks a dry season, as precipitation is more evenly dispersed throughout the year. It is the predominant climate type across much of Western Europe, the Pacific Northwest region of the United States and Canada, portions of central Mexico, southwestern South America, southeastern Australia including Tasmania, New Zealand as well as isolated locations elsewhere. Oceanic climates generally have warm summers and cool (but not cold) winters. They are characterised by a narrower annual range of temperatures than are encountered in other places at a comparable latitude, and generally do not have the extremely dry summers of Mediterranean climates or the hot summers of humid subtropical. Oceanic climates are most dominant in Europe, where they spread much farther inland than in other continents.
Can we conclude that the climate of western europe is a predominantly a marine climate?
A: yes

Q: Twincharger refers to a compound forced induction system used on some piston-type internal combustion engines. It is a combination of an exhaust-driven turbocharger and an engine-driven supercharger, each mitigating the weaknesses of the other. A belt-driven or shaft-driven supercharger offers exceptional response and low-rpm performance as it has no lag time between the application of throttle and pressurization of the manifold (assuming that it is a positive-displacement supercharger such as a Roots type or twin-screw and not a Centrifugal compressor supercharger, which does not provide boost until the engine has reached higher RPMs). When combined with a large turbocharger -- if the ''turbo'' was used by itself, it would offer unacceptable lag and poor response in the low-rpm range -- the proper combination of the two can offer a zero-lag powerband with high torque at lower engine speeds and increased power at the higher end. Twincharging is therefore desirable for small-displacement motors (such as VW's 1.4TSI), especially those with a large operating rpm, since they can take advantage of an artificially broad torque band over a large speed range.
Can we conclude that is it possible to have a supercharger and turbo?
A:
yes
