Context and question: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors.
What color LEDs are now not used more?
Answer: unanswerable
Context and question: During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother. Oxford fired twice, but either both bullets missed or, as he later claimed, the guns had no shot. He was tried for high treason and found guilty, but was acquitted on the grounds of insanity. In the immediate aftermath of the attack, Victoria's popularity soared, mitigating residual discontent over the Hastings affair and the bedchamber crisis. Her daughter, also named Victoria, was born on 21 November 1840. The Queen hated being pregnant, viewed breast-feeding with disgust, and thought newborn babies were ugly. Nevertheless, over the following seventeen years, she and Albert had a further eight children: Albert Edward, Prince of Wales (b. 1841), Alice (b. 1843), Alfred (b. 1844), Helena (b. 1846), Louise (b. 1848), Arthur (b. 1850), Leopold (b. 1853) and Beatrice (b. 1857).
How old was Edward Oxford?
Answer: 18
Context and question: Within the Army, British officers who initially trained at the company's own academy at the Addiscombe Military Seminary, always outranked Indians, no matter how long their service. The highest rank to which an Indian soldier could aspire was Subadar-Major (or Rissaldar-Major in cavalry units), effectively a senior subaltern equivalent. Promotion for both British and Indian soldiers was strictly by seniority, so Indian soldiers rarely reached the commissioned ranks of Jamadar or Subadar before they were middle aged at best. They received no training in administration or leadership to make them independent of their British officers.
Who received no training for the military?
