The Gurjar Pratihar Empire acted as a barrier for Arab invaders from the 8th to the 11th century. The chief accomplishment of the Gurjara Pratihara empire lies in its successful resistance to foreign invasions from the west, starting in the days of Junaid. Historian R. C. Majumdar says that this was openly acknowledged by the Arab writers. He further notes that historians of India have wondered at the slow progress of Muslim invaders in India, as compared with their rapid advance in other parts of the world. Now there seems little doubt that it was the power of the Gurjara Pratihara army that effectively barred the progress of the Arabs beyond the confines of Sindh, their first conquest for nearly 300 years.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Arab conquest was limited to what region?
Ah, so.. Sindh

In flood lamps used for photographic lighting, the tradeoff is made in the other direction. Compared to general-service bulbs, for the same power, these bulbs produce far more light, and (more importantly) light at a higher color temperature, at the expense of greatly reduced life (which may be as short as two hours for a type P1 lamp). The upper temperature limit for the filament is the melting point of the metal. Tungsten is the metal with the highest melting point, 3,695 K (6,191 F). A 50-hour-life projection bulb, for instance, is designed to operate only 50 C (122 F) below that melting point. Such a lamp may achieve up to 22 lumens per watt, compared with 17.5 for a 750-hour general service lamp.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the typical life of a P1 lamp?
Ah, so.. as short as two hours

Charleston's oldest community theater group, the Footlight Players, has provided theatrical productions since 1931. A variety of performing arts venues includes the historic Dock Street Theatre. The annual Charleston Fashion Week held each spring in Marion Square brings in designers, journalists, and clients from across the nation. Charleston is known for its local seafood, which plays a key role in the city's renowned cuisine, comprising staple dishes such as gumbo, she-crab soup, fried oysters, Lowcountry boil, deviled crab cakes, red rice, and shrimp and grits. Rice is the staple in many dishes, reflecting the rice culture of the Low Country. The cuisine in Charleston is also strongly influenced by British and French elements.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Charleston is known for what type of food?
Ah, so..
