Input: Read this: The use of alloys by humans started with the use of meteoric iron, a naturally occurring alloy of nickel and iron. It is the main constituent of iron meteorites which occasionally fall down on Earth from outer space. As no metallurgic processes were used to separate iron from nickel, the alloy was used as it was. Meteoric iron could be forged from a red heat to make objects such as tools, weapons, and nails. In many cultures it was shaped by cold hammering into knives and arrowheads. They were often used as anvils. Meteoric iron was very rare and valuable, and difficult for ancient people to work.
Question: What was formed from meteoric iron using hot hammering?

Output: unanswerable

Input: Read this: To the southwest, the principality of Halych had developed trade relations with its Polish, Hungarian and Lithuanian neighbours and emerged as the local successor to Kievan Rus'. In 1199, Prince Roman Mstislavich united the two previously separate principalities. In 1202 he conquered Kiev, and assumed the title of Grand Duke of Kievan Rus', which was held by the rulers of Vladimir-Suzdal since 1169. His son, Prince Daniil (r. 12381264) looked for support from the West. He accepted a crown as a "Rex Rusiae" ("King of Russia") from the Roman papacy, apparently doing so without breaking with Constantinople. In 1370, the patriarch of the Eastern Orthodox Church in Constantinople granted the King of Poland a metropolitan for his Russian subjects. Lithuanian rulers also requested and received a metropolitan for Novagrudok shortly afterwards. Cyprian, a candidate pushed by the Lithuanian rulers, became Metropolitan of Kiev in 1375 and metropolitan of Moscow in 1382; this way the church in the Russian countries was reunited for some time. In 1439, Kiev became the seat of a separate "Metropolitan of Kiev, Galich and all Rus'" for all Greek Orthodox Christians under Polish-Lithuanian rule.
Question: When did Prince Daniil rule?

unanswerable
