Input: Copper
Chromobacterium violaceum and Pseudomonas fluorescens can both mobilize solid copper, as a cyanide compound. The ericoid mycorrhizal fungi associated with Calluna, Erica and Vaccinium can grow in copper metalliferous soils. The ectomycorrhizal fungus Suillus luteus protects young pine trees from copper toxicity. A sample of the fungus Aspergillus niger was found growing from gold mining solution; and was found to contain cyano metal complexes; such as gold, silver, copper iron and zinc. The fungus also plays a role in the solubilization of heavy metal sulfides.

What fungus helps to soften heavy metal sulfides?
Output: fungus Aspergillus

Input: Article: In 1981 a team of researchers from the Maison de l'Orient et de la Mediterranee, including Jacques Cauvin and Oliver Aurenche divided Near East neolithic chronology into ten periods (0 to 9) based on social, economic and cultural characteristics. In 2002 Danielle Stordeur and Frederic Abbes advanced this system with a division into five periods. Natufian (1) between 12,000 and 10,200 BC, Khiamian (2) between 10,200-8,800 BC, PPNA: Sultanian (Jericho), Mureybetian, early PPNB (PPNB ancien) (3) between 8,800-7,600 BC, middle PPNB (PPNB moyen) 7,600-6,900 BC, late PPNB (PPNB recent) (4) between 7,500 and 7,000 BC and a PPNB (sometimes called PPNC) transitional stage (PPNB final) (5) where Halaf and dark faced burnished ware begin to emerge between 6,900-6,400 BC. They also advanced the idea of a transitional stage between the PPNA and PPNB between 8,800 and 8,600 BC at sites like Jerf el Ahmar and Tell Aswad.

Now answer this question: What traits did researchers use to divide the ten periods?

Output: social, economic and cultural characteristics

Article: Dvaitadvaita was proposed by Nimbarka, a 13th-century Vaishnava Philosopher from the Andhra region. According to this philosophy there are three categories of existence: Brahman, soul, and matter. Soul and matter are different from Brahman in that they have attributes and capacities different from Brahman. Brahman exists independently, while soul and matter are dependent. Thus soul and matter have an existence that is separate yet dependent. Further, Brahman is a controller, the soul is the enjoyer, and matter the thing enjoyed. Also, the highest object of worship is Krishna and his consort Radha, attended by thousands of gopis; of the Vrindavan; and devotion consists in self-surrender.

Question: How many categories of existence are there in Dvaitadvaita?
Ans: three

Here is a question about this article: The city walls include God's House Tower, built in 1417, the first purpose-built artillery fortification in England. Over the years it has been used as home to the city's gunner, the Town Gaol and even as storage for the Southampton Harbour Board. Until September 2011, it housed the Museum of Archaeology. The walls were completed in the 15th century, but later development of several new fortifications along Southampton Water and the Solent by Henry VIII meant that Southampton was no longer dependent upon its fortifications.
What is the answer to this question: What's the name of the wall tower that was the first of its kind in England built for artillery purposes?
****
So... God's House Tower

The problem: Answer a question about this article:
The quail is a small to medium-sized, cryptically coloured bird. In its natural environment, it is found in bushy places, in rough grassland, among agricultural crops, and in other places with dense cover. It feeds on seeds, insects, and other small invertebrates. Being a largely ground-dwelling, gregarious bird, domestication of the quail was not difficult, although many of its wild instincts are retained in captivity. It was known to the Egyptians long before the arrival of chickens and was depicted in hieroglyphs from 2575 BC. It migrated across Egypt in vast flocks and the birds could sometimes be picked up off the ground by hand. These were the common quail (Coturnix coturnix), but modern domesticated flocks are mostly of Japanese quail (Coturnix japonica) which was probably domesticated as early as the 11th century AD in Japan. They were originally kept as songbirds, and they are thought to have been regularly used in song contests.
From what country do most domesticated quails today descend from ?
****
The answer: modern domesticated flocks are mostly of Japanese quail (Coturnix japonica)

The problem: Answer a question about this article:
The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.
Which was built first, the first elevator shaft or the first elevator?
****
The answer:
first elevator shaft
