The problem: Answer a question about this article:
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?
****
The answer: 5500 BC

Another study on men and women's patterns of sexual arousal confirmed that men and women have different patterns of arousal, independent of their sexual orientations. The study found that women's genitals become aroused to both human and nonhuman stimuli from movies showing humans of both genders having sex (heterosexual and homosexual) and from videos showing non-human primates (bonobos) having sex. Men did not show any sexual arousal to non-human visual stimuli, their arousal patterns being in line with their specific sexual interest (women for heterosexual men and men for homosexual men).

Are the patterns related to orientation?
Answer: independent of their sexual orientations


Problem: Continental Portugal's 89,015 km2 (34,369 sq mi) territory is serviced by four international airports located near the principal cities of Lisbon, Porto, Faro and Beja. Lisbon's geographical position makes it a stopover for many foreign airlines at several airports within the country. The primary flag-carrier is TAP Portugal, although many other domestic airlines provide services within and without the country. The government decided to build a new airport outside Lisbon, in Alcochete, to replace Lisbon Portela Airport, though this plan has been stalled due to the austerity. Currently, the most important airports are in Lisbon, Porto, Faro, Funchal (Madeira), and Ponta Delgada (Azores), managed by the national airport authority group ANA – Aeroportos de Portugal.
Near what cities are the Portuguese airports located?
The answer is the following: Lisbon, Porto, Faro and Beja


As the Grand Duchy of Finland was part of the Russian Empire from 1809 to 1918, a number of Russian speakers have remained in Finland. There are 33,400 Russian-speaking Finns, amounting to 0.6% of the population. Five thousand (0.1%) of them are late 19th century and 20th century immigrants or their descendants, and the remaining majority are recent immigrants who moved there in the 1990s and later.[citation needed] Russian is spoken by 1.4% of the population of Finland according to a 2014 estimate from the World Factbook.
What percent of Finns speak Russian?
0.6%
