Input: Article: During the First Opium War, the British navy defeated Eight Banners forces at Ningbo and Dinghai. Under the terms of the Treaty of Nanking, signed in 1843, Ningbo became one of the five Chinese treaty ports opened to virtually unrestricted foreign trade. Much of Zhejiang came under the control of the Taiping Heavenly Kingdom during the Taiping Rebellion, which resulted in a considerable loss of life in the province. In 1876, Wenzhou became Zhejiang's second treaty port.

Now answer this question: When was the Treaty of Nanking signed?

Output: 1843

Input: Article: The monastic communities of the Judean Desert also decorated their monasteries with mosaic floors. The Monastery of Martyrius was founded in the end of the 5th century and it was re-discovered in 1982–85. The most important work of art here is the intact geometric mosaic floor of the refectory although the severely damaged church floor was similarly rich. The mosaics in the church of the nearby Monastery of Euthymius are of later date (discovered in 1930). They were laid down in the Umayyad era, after a devastating earthquake in 659. Two six pointed stars and a red chalice are the most important surviving features.

Now answer this question: Where in the Monastery of Martyrius is the most important mosaic work?

Output: the refectory

Input: Article: Commonly called 'light bulbs', lamps are the removable and replaceable part of a light fixture, which converts electrical energy into electromagnetic radiation. While lamps have traditionally been rated and marketed primarily in terms of their power consumption, expressed in watts, proliferation of lighting technology beyond the incandescent light bulb has eliminated the correspondence of wattage to the amount of light produced. For example, a 60 W incandescent light bulb produces about the same amount of light as a 13 W compact fluorescent lamp. Each of these technologies has a different efficacy in converting electrical energy to visible light. Visible light output is typically measured in lumens. This unit only quantifies the visible radiation, and excludes invisible infrared and ultraviolet light. A wax candle produces on the close order of 13 lumens, a 60 watt incandescent lamp makes around 700 lumens, and a 15-watt compact fluorescent lamp produces about 800 lumens, but actual output varies by specific design. Rating and marketing emphasis is shifting away from wattage and towards lumen output, to give the purchaser a directly applicable basis upon which to select a lamp.

Now answer this question: What is the removable and replaceable part of a light fixture?

Output:
light bulbs
