Article: The British dealt with range measurement first, when it was realised that range was the key to producing a better fuse setting. This led to the Height/Range Finder (HRF), the first model being the Barr & Stroud UB2, a 2-metre optical coincident rangefinder mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF was soon joined by the Height/Fuse Indicator (HFI), this was marked with elevation angles and height lines overlaid with fuse length curves, using the height reported by the HRF operator, the necessary fuse length could be read off.

Question: The fuse length could be set using height reported by whom?
Ans: HRF operator


Article: The Grands Magasins Dufayel was a huge department store with inexpensive prices built in 1890 in the northern part of Paris, where it reached a very large new customer base in the working class. In a neighborhood with few public spaces, it provided a consumer version of the public square. It educated workers to approach shopping as an exciting social activity not just a routine exercise in obtaining necessities, just as the bourgeoisie did at the famous department stores in the central city. Like the bourgeois stores, it helped transform consumption from a business transaction into a direct relationship between consumer and sought-after goods. Its advertisements promised the opportunity to participate in the newest, most fashionable consumerism at reasonable cost. The latest technology was featured, such as cinemas and exhibits of inventions like X-ray machines (that could be used to fit shoes) and the gramophone.

Question: What were employees taught that made a shopping experience different? 
Ans: exciting social activity not just a routine exercise in obtaining necessities

Article: During this period, Bengal witnessed an intellectual awakening that is in some way similar to the Renaissance in Europe during the 16th century, although Europeans of that age were not confronted with the challenge and influence of alien colonialism. This movement questioned existing orthodoxies, particularly with respect to women, marriage, the dowry system, the caste system, and religion. One of the earliest social movements that emerged during this time was the Young Bengal movement, which espoused rationalism and atheism as the common denominators of civil conduct among upper caste educated Hindus. It played an important role in reawakening Indian minds and intellect across the sub-continent.

Question: What early social movement occurred during this time of awakening?
Ans:
Young Bengal
