PROBLEM: Passage: Following a life-threatening drug addiction that developed after leaving the Chili Peppers in 1992, Frusciante completed a month of drug rehabilitation at Las Encinas in Pasadena in 1998. Shortly thereafter he was asked to rejoin the band. After several months of writing and recording, the Chili Peppers' next album, Californication was released. The album went on to sell more than 15 million copies worldwide, becoming the Chili Peppers' most successful recording to date. Frusciante's return generated much response from critics, who recognized the album as a commercial revitalization from their previous record, One Hot Minute. A two-year-long, international tour followed, which included several festival appearances, including Woodstock 1999 and Rock in Rio.
The writing and formation of By the Way began immediately following the culmination of Californication's world tour, in the spring of 2001. As with Californication, much of the creation took place in the band members' homes and other practice locations, such as a recording studio stage. Kiedis recalled of the situation: "We started finding some magic and some music and some riffs and some rhythms and some jams and some grooves, and we added to it and subtracted from it and pushed it around and put melodies to it." Frusciante and Kiedis would collaborate for days straight, discussing guitar progressions and sharing lyrics. For Kiedis, "writing By the Way...was a whole different experience from Californication. John was back to himself and brimming with confidence." Prior to recording By the Way, the Chili Peppers decided that they would again have Rick Rubin produce the album. Rubin had, in the past, granted the Chili Peppers creative freedom on their recording material; this was something they thought essential for the album to be unique, and could only occur with his return.
Question: What was Frusciante asked to rejoin after rehab?

SOLUTION: the Chili Peppers.

PROBLEM: Passage: Nansen's Fram expedition of 189396 was an attempt by the Norwegian explorer Fridtjof Nansen to reach the geographical North Pole by harnessing the natural eastwest current of the Arctic Ocean. In the face of much discouragement from other polar explorers, Nansen took his ship Fram to the New Siberian Islands in the eastern Arctic Ocean, froze her into the pack ice, and waited for the drift to carry her towards the pole. Impatient with the slow speed and erratic character of the drift, after 18 months Nansen and a chosen companion, Hjalmar Johansen, left the ship with a team of dogs and sledges and made for the pole. They did not reach it, but they achieved a record Farthest North latitude of 8613.6N before a long retreat over ice and water to reach safety in Franz Josef Land. Meanwhile, Fram continued to drift westward, finally emerging in the North Atlantic Ocean.
The idea for the expedition had arisen after items from the American vessel Jeannette, which had sunk off the north coast of Siberia in 1881, were discovered three years later off the south-west coast of Greenland. The wreckage had obviously been carried across the polar ocean, perhaps across the pole itself. Based on this and other debris recovered from the Greenland coast, the meteorologist Henrik Mohn developed a theory of transpolar drift, which led Nansen to believe that a specially designed ship could be frozen in the pack ice and follow the same track as Jeannette wreckage, thus reaching the vicinity of the pole.
Nansen supervised the construction of a vessel with a rounded hull and other features designed to withstand prolonged pressure from ice. The ship was rarely threatened during her long imprisonment, and emerged unscathed after three years. The scientific observations carried out during this period contributed significantly to the new discipline of oceanography, which subsequently became the main focus of Nansen's scientific work. Fram's drift and Nansen's sledge journey proved conclusively that there were no significant land masses between the Eurasian continents and the North Pole, and confirmed the general character of the north polar region as a deep, ice-covered sea. Although Nansen retired from exploration after this expedition, the methods of travel and survival he developed with Johansen influenced all the polar expeditions, north and south, which followed in the subsequent three decades.
Question: What is the precise geographic name of the pole Nansen and Johansen left the ship with a team of dogs and sledges to make for?

SOLUTION: North Pole.

PROBLEM: Passage: James Barton Longacre (August 11, 1794 January 1, 1869) was an American portraitist and engraver, and the fourth Chief Engraver of the United States Mint from 1844 until his death. Longacre is best known for designing the Indian Head cent, which entered commerce in 1859, and for the designs of the Shield nickel, Flying Eagle cent and other coins of the mid-19th century.
Longacre was born in Delaware County, Pennsylvania, in 1794. He ran away to Philadelphia at age 12, where he became an apprentice in a bookstore. His artistic talent developed and he was released to apprentice in an engraving firm. He struck out on his own in 1819, making a name providing illustrations for popular biographical books. He portrayed the leading men of his day; support from some of them, such as South Carolina Senator John C. Calhoun, led to his appointment as chief engraver after the death of Christian Gobrecht in 1844.
In Longacre's first years as a chief engraver, the Philadelphia Mint was dominated by Mint Director Robert M. Patterson and Chief Coiner Franklin Peale. Conflict between Longacre and the two men developed after Congress ordered a new gold dollar and double eagle, with both to be designed by Longacre. Peale and Patterson nearly had Longacre fired, but the chief engraver was able to convince Treasury Secretary William M. Meredith that he should be retained. Both Patterson and Peale left the Mint in the early 1850s, ending the conflict.
In 1856, Longacre designed the Flying Eagle cent. When that design proved difficult to strike, Longacre was responsible for the replacement, the Indian Head cent, issued beginning in 1859. Other coins designed by Longacre include the silver and nickel three-cent pieces, the Shield nickel, the pattern Washington nickel, and the two-cent piece. In 18661867, he redesigned the coins of Chile. Longacre died suddenly on New Year's Day 1869; he was succeeded by William Barber. Longacre's coins are generally well-regarded today, although they have been criticized for lack of artistic advancement.
Question: What is the full name of the person that was the Chief Engraver after James Barton Longacre?

SOLUTION:
William Barber.
