QUES: PAL LaserDiscs have a slightly longer playing time than NTSC discs, but have fewer audio options. PAL discs only have two audio tracks, consisting of either two analog-only tracks on older PAL LDs, or two digital-only tracks on newer discs. In comparison, later NTSC LDs are capable of carrying four tracks (two analog and two digital). On certain releases, one of the analog tracks is used to carry a modulated AC-3 signal for 5.1 channel audio (for decoding and playback by newer LD players with an "AC-3 RF" output). However, older NTSC LDs made before 1984 (such as the original DiscoVision discs) only have two analog audio tracks.
Which has a longer playing time: PAL LaserDiscs or NTSC discs?

ANS: PAL LaserDiscs

QUES: Even before Han's expansion into Central Asia, diplomat Zhang Qian's travels from 139 to 125 BC had established Chinese contacts with many surrounding civilizations. Zhang encountered Dayuan (Fergana), Kangju (Sogdiana), and Daxia (Bactria, formerly the Greco-Bactrian Kingdom); he also gathered information on Shendu (Indus River valley of North India) and Anxi (the Parthian Empire). All of these countries eventually received Han embassies. These connections marked the beginning of the Silk Road trade network that extended to the Roman Empire, bringing Han items like silk to Rome and Roman goods such as glasswares to China.
Which network was used to exchange goods with Rome?

ANS: Silk Road

QUES: The most notable difference is that, contrary to other European heraldic systems, the Jews, Muslim Tatars or another minorities would be given the noble title. Also, most families sharing origin would also share a coat-of-arms. They would also share arms with families adopted into the clan (these would often have their arms officially altered upon ennoblement). Sometimes unrelated families would be falsely attributed to the clan on the basis of similarity of arms. Also often noble families claimed inaccurate clan membership. Logically, the number of coats of arms in this system was rather low and did not exceed 200 in late Middle Ages (40,000 in the late 18th century).
How would unrelated families be attributed to the clan?

ANS:
on the basis of similarity of arms
