Problem: Eta Carinae is the most prominent variable star in Carina; with a mass of approximately 100 solar masses and 4 million times as bright as the Sun. It was first discovered to be unusual in 1677, when its magnitude suddenly rose to 4, attracting the attention of Edmond Halley. Eta Carinae is inside NGC 3372, commonly called the Carina Nebula. It had a long outburst in 1827, when it brightened to magnitude 1, only fading to magnitude 1.5 in 1828. Its most prominent outburst made Eta Carinae the equal of Sirius; it brightened to magnitude 1.5 in 1843. However, since 1843, Eta Carinae has remained relatively placid, having a magnitude between 6.5 and 7.9. However, in 1998, it brightened again, though only to magnitude 5.0, a far less drastic outburst. Eta Carinae is a binary star, with a companion that has a period of 5.5 years; the two stars are surrounded by the Homunculus Nebula, which is composed of gas that was ejected in 1843.
Answer this question based on the article: How many years after Eta Carinae was first discovered to be unusual did it brighten to magnitude 1.5?
A: 166

Problem: During the 9th century, Norway was divided between several local kings controlling their own fiefdoms. By the end of the century, King Harald Fairhair managed, mainly due to the military superiority gained by his alliance with Sigurd Ladejarl of Nidaros, to subjugate these mini-kingdoms, and he created a unified Norwegian state. This alliance came apart after Harald's death. The jarls of Lade and various descendants of Harald Fairhair would spend the next century interlocked in feuds over power. As well as power politics, religion also played a part in these conflicts, as two of the descendants of Harald Fairhair, Hakon the Good and Olaf Tryggvason attempted to convert the then heathen Norwegians to Christianity. In the year 1000, Svein and Erik of Lade took control over Norway, being supported by the Danish King Svein. In 1015, Olaf Haraldsson, representing the descendants of Harald Fairhair, returned from one of his Viking trips and was immediately elected as King of Norway. In June 1016, he won the Battle at Nesjar against the Jarls of Lade. Olav Haraldsson's success in becoming King of Norway was helped by the Danes being kept occupied with the ongoing fighting in England. In the year 1028, the Danish King Cnut the Great made an alliance with the Lades, and Olaf had to go into exile in Kievan Rus . In the year of 1029 the last Lade, Hakon Jarl, drowned and Olaf returned to Norway with his army to regain his throne and the Kingdom of Norway.
Answer this question based on the article: Ho took over Norway first, Svein and Erik of Lade or Olav Haraldsson?
