Input: Article: The main industries are mineral based, agriculture based, and textile based. Rajasthan is the second largest producer of polyester fibre in India. The Pali and Bhilwara District produces more cloth than Bhiwandi, Maharashtra and the bhilwara is the largest city in suitings production and export and Pali is largest city in cotton and polyster in blouse pieces and rubia production and export. Several prominent chemical and engineering companies are located in the city of Kota, in southern Rajasthan. Rajasthan is pre-eminent in quarrying and mining in India. The Taj Mahal was built from the white marble which was mined from a town called Makrana. The state is the second largest source of cement in India. It has rich salt deposits at Sambhar, copper mines at Khetri, Jhunjhunu, and zinc mines at Dariba, Zawar mines and Rampura Aghucha (opencast) near Bhilwara. Dimensional stone mining is also undertaken in Rajasthan. Jodhpur sandstone is mostly used in monuments, important buildings and residential buildings. This stone is termed as "chittar patthar". Jodhpur leads in Handicraft and Guar Gum industry. Rajasthan is also a part of the Mumbai-Delhi Industrial corridor is set to benefit economically. The State gets 39% of the DMIC, with major districts of Jaipur, Alwar, Kota and Bhilwara benefiting.

Now answer this question: What type of fibre is Rajasthan ranked 2nd in production of?

Output: polyester fibre

Input: Article: During ordinary operation, the tungsten of the filament evaporates; hotter, more-efficient filaments evaporate faster. Because of this, the lifetime of a filament lamp is a trade-off between efficiency and longevity. The trade-off is typically set to provide a lifetime of several hundred to 2,000 hours for lamps used for general illumination. Theatrical, photographic, and projection lamps may have a useful life of only a few hours, trading life expectancy for high output in a compact form. Long-life general service lamps have lower efficiency but are used where the cost of changing the lamp is high compared to the value of energy used.

Now answer this question: Which types of lamps may have particularly short lives?

Output: Theatrical, photographic, and projection lamps

Input: Article: Brigham Young University's origin can be traced back to 1862 when a man named Warren Dusenberry started a Provo school in a prominent adobe building called Cluff Hall, which was located in the northeast corner of 200 East and 200 North. On October 16, 1875, Brigham Young, then president of the LDS Church, personally purchased the Lewis Building after previously hinting that a school would be built in Draper, Utah in 1867. Hence, October 16, 1875 is commonly held as BYU's founding date. Said Young about his vision: "I hope to see an Academy established in Provo... at which the children of the Latter-day Saints can receive a good education unmixed with the pernicious atheistic influences that are found in so many of the higher schools of the country."

Now answer this question: What year can BYU's origin be traced to with a building called Cluff Hall?

Output:
1862
