[EX Q]: Passage: Olvir Hnufa or Ölvir hnúfa was a Norwegian commander in a clan and poet of the late ninth and early tenth centuries, known from, among other sources, Egil's Saga, Skaldatal and the Prose Edda. Olvir was the son of the viking Berle-Kari and brother-in-law of Kveldulf Bjalfason, who married Olvir's sister Salbjorg Karadottir; he was thus uncle to Skallagrim and Thorolf Kveldulfsson and great uncle to the famous poet Egil Skallagrimsson. Olvir also had a brother named Eyvind Lambi. Olvir was a prominent member of the court of King Harald Fairhair, who united Norway under his rule in the late ninth or early tenth century. Among other famous poets, he served as one of King Harald's court poets. He also served as a warrior in Harald's retinue, and fought at the pivotal Battle of Hafrsfjord on the king's flagship. He is best known for his involvement in the conflict between Harald and Olvir's kinsman Thorolf Kveldulfsson, which ended with the latter's death. Only a few fragments of Olvir's poetry survive.

Elfyn Evans climbed up three places in the afternoon loop and edged Jari-Matti Latvala by a second. Dani Sordo completed the day in sixth, only one-tenth of a second ahead of Esapekka Lappi, who failed to come to terms with dirt dragged onto the roads by the early starters. Craig Breen lost some time due to being caught in a heavy rain shower in the early stage in the eighth place, followed by Andreas Mikkelsen, who was struggling with his i20's handling and chose to change his driving style, in ninth, only one second behind. Teemu Suninen, driving a third Fiesta, in tenth. Lacking of power caused Mads Østberg to fail to find the pace like Finland, which made him cleared the day off the leaderboard in eleventh overall.

[EX Q]: Passage: The Chinese giant salamander (Andrias davidianus) is one of the largest salamanders and one of the largest amphibians in the world. It is fully aquatic and is endemic to rocky mountain streams and lakes in the Yangtze river basin of central China. Either it or a close relative has been introduced to Kyoto Prefecture in Japan and Taiwan. It is considered critically endangered in the wild due to habitat loss, pollution, and overcollection, as it is considered a delicacy and used in traditional Chinese medicine. On farms in central China, it is extensively farmed and sometimes bred, although many of the salamanders on the farms are caught in the wild. It has been listed as one of the top-10 "focal species" in 2008 by the Evolutionarily Distinct and Globally Endangered project. The Chinese giant salamander is considered to be a "living fossil". Although protected under Chinese law and CITES Appendix I, the wild population has declined by more than an estimated 80% since the 1950s. Although traditionally recognized as one of two living species of Andrias salamander in Asia, the other being the Japanese giant salamander, evidence indicates that the Chinese giant salamander may be composed of at least five cryptic species, further compounding each individual species' endangerment.
 Link Information: The Japanese giant salamander was first catalogued by Europeans when the resident physician of Dejima Island in Nagasaki, Philipp Franz von Siebold, captured an individual and shipped it back to Leiden in the Netherlands, in the 1820s. Question: When was the Japanese giant salamander first discovered?
[EX A]:
Answer:  in the 1820s
