Passage: Another potential weapon system for anti-aircraft use is the laser. Although air planners have imagined lasers in combat since the late 1960s, only the most modern laser systems are currently reaching what could be considered "experimental usefulness". In particular the Tactical High Energy Laser can be used in the anti-aircraft and anti-missile role. If current developments continue, some[who?] believe it is reasonable to suggest that lasers will play a major role in air defence starting in the next ten years. Question: When do some people believe that lasers can play a more prominent role in air defence?

Passage: The Pamiri people of Gorno-Badakhshan Autonomous Province in the southeast, bordering Afghanistan and China, though considered part of the Tajik ethnicity, nevertheless are distinct linguistically and culturally from most Tajiks. In contrast to the mostly Sunni Muslim residents of the rest of Tajikistan, the Pamiris overwhelmingly follow the Ismaili sect of Islam, and speak a number of Eastern Iranian languages, including Shughni, Rushani, Khufi and Wakhi. Isolated in the highest parts of the Pamir Mountains, they have preserved many ancient cultural traditions and folk arts that have been largely lost elsewhere in the country. Question: How are they different than most Tajiks?
