Input: Article: Raleigh receives an average of 6.0 inches (15.2 cm) of snow in winter. Freezing rain and sleet also occur most winters, and occasionally the area experiences a major damaging ice storm. On January 24–25, 2000, Raleigh received its greatest snowfall from a single storm – 20.3 inches (52 cm) – the Winter Storm of January 2000. Storms of this magnitude are generally the result of cold air damming that affects the city due to its proximity to the Appalachian Mountains. Winter storms have caused traffic problems in the past as well.

Now answer this question: What mountains are the city near?

Output: Appalachian Mountains.


Article: Transport in the Republic of the Congo includes land, air and water transportation. The country's rail system was built by forced laborers during the 1930s and largely remains in operation. There are also over 1000 km of paved roads and two major international airports (Maya-Maya Airport and Pointe Noire Airport) which have flights to Paris and many African cities. The country also has a large port on the Atlantic Ocean at Pointe-Noire and others along the Congo River at Brazzaville and Impfondo.

Question: On what ocean is a major port located?
Ans: Atlantic Ocean


Here is a question about this article: There is no clear consensus on the nature or even the existence of God. The Abrahamic conceptions of God include the monotheistic definition of God in Judaism, the trinitarian view of Christians, and the Islamic concept of God. The dharmic religions differ in their view of the divine: views of God in Hinduism vary by region, sect, and caste, ranging from monotheistic to polytheistic to atheistic. Divinity was recognized by the historical Buddha, particularly Śakra and Brahma. However, other sentient beings, including gods, can at best only play a supportive role in one's personal path to salvation. Conceptions of God in the latter developments of the Mahayana tradition give a more prominent place to notions of the divine.[citation needed]
What is the answer to this question: Does hinduism only believe in a single god?
****
So... ranging from monotheistic to polytheistic to atheistic


The problem: Answer a question about this article:
Small, cheap discoidal ceramic capacitors have existed since the 1930s, and remain in widespread use. Since the 1980s, surface mount packages for capacitors have been widely used. These packages are extremely small and lack connecting leads, allowing them to be soldered directly onto the surface of printed circuit boards. Surface mount components avoid undesirable high-frequency effects due to the leads and simplify automated assembly, although manual handling is made difficult due to their small size.
What is one difficulty when using surface mount components?
****
The answer: manual handling is made difficult due to their small size


Problem: Please answer a question about the following article about Rajasthan:
Modern Rajasthan includes most of Rajputana, which comprises the erstwhile nineteen princely states, two chiefships, and the British district of Ajmer-Merwara. Marwar (Jodhpur), Bikaner, Mewar (Chittorgarh), Alwar and Dhundhar (Jaipur) were some of the main Rajput princely states. Bharatpur and Dholpur were Jat princely states whereas Tonk was a princely state under a Muslim Nawab. Rajput families rose to prominence in the 6th century CE. The Rajputs put up a valiant resistance to the Islamic invasions and protected this land with their warfare and chivalry for more than 500 years. They also resisted Mughal incursions into India and thus contributed to their slower-than-anticipated access to the Indian subcontinent. Later, the Mughals, through skilled warfare, were able to get a firm grip on northern India, including Rajasthan. Mewar led other kingdoms in its resistance to outside rule. Most notably, Rana Sanga fought the Battle of Khanua against Babur, the founder of the Mughal empire.
Bharatpur is an example of what kind of state?
A: princely


Question: Read this and answer the question

Copper occurs naturally as native copper and was known to some of the oldest civilizations on record. It has a history of use that is at least 10,000 years old, and estimates of its discovery place it at 9000 BC in the Middle East; a copper pendant was found in northern Iraq that dates to 8700 BC. There is evidence that gold and meteoric iron (but not iron smelting) were the only metals used by humans before copper. The history of copper metallurgy is thought to have followed the following sequence: 1) cold working of native copper, 2) annealing, 3) smelting, and 4) the lost wax method. In southeastern Anatolia, all four of these metallurgical techniques appears more or less simultaneously at the beginning of the Neolithic c. 7500 BC. However, just as agriculture was independently invented in several parts of the world, copper smelting was invented locally in several different places. It was probably discovered independently in China before 2800 BC, in Central America perhaps around 600 AD, and in West Africa about the 9th or 10th century AD. Investment casting was invented in 4500–4000 BC in Southeast Asia and carbon dating has established mining at Alderley Edge in Cheshire, UK at 2280 to 1890 BC. Ötzi the Iceman, a male dated from 3300–3200 BC, was found with an axe with a copper head 99.7% pure; high levels of arsenic in his hair suggest his involvement in copper smelting. Experience with copper has assisted the development of other metals; in particular, copper smelting led to the discovery of iron smelting. Production in the Old Copper Complex in Michigan and Wisconsin is dated between 6000 and 3000 BC. Natural bronze, a type of copper made from ores rich in silicon, arsenic, and (rarely) tin, came into general use in the Balkans around 5500 BC.[citation needed]

When did Natural bronze start to be used by the general public?
Answer:
5500 BC
