Q: Passage: In late 1996, after more than five years of addiction to heroin, Frusciante quit it cold turkey. However, months later he was still unable to break addictions to crack cocaine and alcohol. In January 1998, urged by longtime friend Bob Forrest, Frusciante checked into Las Encinas, a drug rehabilitation clinic in Pasadena, to begin his recovery. Upon arrival, he was diagnosed with a potentially lethal oral infection, which could only be alleviated by removing all of his rotten teeth and replacing them with dental implants. He also received skin grafts to help repair the abscesses on his ravaged arms. About a month later, Frusciante checked out of Las Encinas and re-entered society.Fully recovered and once again healthy, Frusciante began living a more spiritual, ascetic lifestyle. He changed his diet, becoming more health-conscious and eating mostly unprocessed foods. Through regular practice of vipassana and yoga, he discovered the effect that self-discipline has on the body. To maintain his increased spiritual awareness and reduce distraction from his music, Frusciante decided to abstain from sexual activity stating: "I'm very well without it." All of these changes in his life have led him to a complete change in his attitude toward drugs:
I don't need to take drugs. I feel so much more high all the time right now because of the type of momentum that a person can get going when you really dedicate yourself to something that you really love. I don't even consider doing them, they're completely silly. Between my dedication to trying to constantly be a better musician and eating my health foods and doing yoga, I feel so much more high than I did for the last few years of doing drugs.
At this point I'm the happiest person in the world. These things do not fuck with me at all, and I'm so proud of that—you don't know how proud I am. It's such a beautiful thing to be able to face life, to face yourself, without hiding behind drugs; without having to have anger towards people who love you. There are people who are scared of losing stuff, but you don't lose anything for any other reason than if you just give up on yourself. 
Question: What is the name of the person that was diagnosed with a potentially lethal oral infection?

A: Frusciante.

Q: Passage: The most famous geyser in the park, and perhaps the world, is Old Faithful geyser, located in Upper Geyser Basin. Castle Geyser, Lion Geyser and Beehive Geyser are in the same basin. The park contains the largest active geyser in the world—Steamboat Geyser in the Norris Geyser Basin. A study that was completed in 2011 found that at least 1283 geysers have erupted in Yellowstone.  Of these, an average of 465 are active in a given year.  Yellowstone contains at least 10,000 thermal features altogether. Half of the world's geysers and hydrothermal features are concentrated in Yellowstone.
In May 2001, the U.S. Geological Survey, Yellowstone National Park, and the University of Utah created the Yellowstone Volcano Observatory (YVO), a partnership for long-term monitoring of the geological processes of the Yellowstone Plateau volcanic field, for disseminating information concerning the potential hazards of this geologically active region.In 2003, changes at the Norris Geyser Basin resulted in the temporary closure of some trails in the basin. New fumaroles were observed, and several geysers showed enhanced activity and increasing water temperatures. Several geysers became so hot that they were transformed into purely steaming features; the water had become superheated and they could no longer erupt normally. This coincided with the release of reports of a multiple year United States Geological Survey research project which mapped the bottom of Yellowstone Lake and identified a structural dome that had uplifted at some time in the past. Research indicated that these uplifts posed no immediate threat of a volcanic eruption, since they may have developed long ago, and there had been no temperature increase found near the uplifts. On March 10, 2004, a biologist discovered 5 dead bison which apparently had inhaled toxic geothermal gases trapped in the Norris Geyser Basin by a seasonal atmospheric inversion. This was closely followed by an upsurge of earthquake activity in April 2004. In 2006, it was reported that the Mallard Lake Dome and the Sour Creek Dome—areas that have long been known to show significant changes in their ground movement—had risen at a rate of 1.5 to 2.4 inches (3.8 to 6.1 cm) per year from mid–2004 through 2006. As of late 2007, the uplift has continued at a reduced rate. These events inspired a great deal of media attention and speculation about the geologic future of the region. Experts responded to the conjecture by informing the public that there was no increased risk of a volcanic eruption in the near future. However, these changes demonstrate the dynamic nature of the Yellowstone hydrothermal system. 
Question: What is the full name of the park in which half of the world's geysers and hydrothermal features are concentrated?

A:
Yellowstone National Park.
