Input: Article: As of 2005, there were over 50 churches recognized as cardinalatial deaconries, though there were only 30 cardinals of the order of deacons. Cardinal deacons have long enjoyed the right to "opt for the order of cardinal priests" (optazione) after they have been cardinal deacons for 10 years. They may on such elevation take a vacant "title" (a church allotted to a cardinal priest as the church in Rome with which he is associated) or their diaconal church may be temporarily elevated to a cardinal priest's "title" for that occasion. When elevated to cardinal priests, they take their precedence according to the day they were first made cardinal deacons (thus ranking above cardinal priests who were elevated to the college after them, regardless of order).

Now answer this question: How many years before a cardinal deacon can choose the order of the cardinal priests?

Output: 10 years

Input: Article: Some alloys occur naturally, such as electrum, which is an alloy that is native to Earth, consisting of silver and gold. Meteorites are sometimes made of naturally occurring alloys of iron and nickel, but are not native to the Earth. One of the first alloys made by humans was bronze, which is made by mixing the metals tin and copper. Bronze was an extremely useful alloy to the ancients, because it is much stronger and harder than either of its components. Steel was another common alloy. However, in ancient times, it could only be created as an accidental byproduct from the heating of iron ore in fires (smelting) during the manufacture of iron. Other ancient alloys include pewter, brass and pig iron. In the modern age, steel can be created in many forms. Carbon steel can be made by varying only the carbon content, producing soft alloys like mild steel or hard alloys like spring steel. Alloy steels can be made by adding other elements, such as molybdenum, vanadium or nickel, resulting in alloys such as high-speed steel or tool steel. Small amounts of manganese are usually alloyed with most modern-steels because of its ability to remove unwanted impurities, like phosphorus, sulfur and oxygen, which can have detrimental effects on the alloy. However, most alloys were not created until the 1900s, such as various aluminium, titanium, nickel, and magnesium alloys. Some modern superalloys, such as incoloy, inconel, and hastelloy, may consist of a multitude of different components.

Now answer this question: Around what time where alloys starting to get made by humans?

Output: 1900s

Input: Article: There is a project involving the future relocation of Plymouth City Council's headquarters, the civic centre, to the current location of the Bretonside bus station; it would involve both the bus station and civic centre being demolished and a rebuilt together at the location with the land from the civic centre being sold off. Other suggestions include the demolition of the Plymouth Pavilions entertainment arena to create a canal "boulevard" linking Millbay to the city centre. Millbay is being regenerated with mixed residential, retail and office space alongside the ferry port.

Now answer this question: To connect Millbay to the city centre, what would need to be destroyed?

Output:
the Plymouth Pavilions entertainment arena
