Problem: Question: "What, according to Thapar, is given too little weight in considerations of Indian history?" Context: "Romila Thapar notes that the division into Hindu-Muslim-British periods of Indian history gives too much weight to "ruling dynasties and foreign invasions", neglecting the social-economic history which often showed a strong continuity. The division into Ancient-Medieval-Modern periods overlooks the fact that the Muslim conquests occurred gradually during which time many things came and went off, while the south was never completely conquered. According to Thapar, a periodisation could also be based on "significant social and economic changes", which are not strictly related to a change of ruling powers.[note 1]" Answer:

A: social-economic history

Problem: Question: "What did the crew do?" Context: "Nevertheless, it was radar that proved to be critical weapon in the night battles over Britain from this point onward. Dowding had introduced the concept of airborne radar and encouraged its usage. Eventually it would become a success. On the night of 22/23 July 1940, Flying Officer Cyril Ashfield (pilot), Pilot Officer Geoffrey Morris (Observer) and Flight Sergeant Reginald Leyland (Air Intercept radar operator) of the Fighter Interception Unit became the first pilot and crew to intercept and destroy an enemy aircraft using onboard radar to guide them to a visual interception, when their AI night fighter brought down a Do 17 off Sussex. On 19 November 1940 the famous RAF night fighter ace John Cunningham shot down a Ju 88 bomber using airborne radar, just as Dowding had predicted." Answer:

A: became the first pilot and crew to intercept and destroy an enemy aircraft using onboard radar to guide them to a visual interception

Problem: Question: "What was the custom in Ottoman Empire during the time of carpet weaving?" Context: "The art of carpet weaving was particularly significant in the Ottoman Empire, carpets having an immense importance both as decorative furnishings, rich in religious and other symbolism, and as a practical consideration, as it was customary to remove one's shoes in living quarters. The weaving of such carpets originated in the nomadic cultures of central Asia (carpets being an easily transportable form of furnishing), and was eventually spread to the settled societies of Anatolia. Turks used carpets, rugs and kilims not just on the floors of a room, but also as a hanging on walls and doorways, where they provided additional insulation. They were also commonly donated to mosques, which often amassed large collections of them." Answer:

A:
remove one's shoes in living quarters
