Question: Passage: Nine Inch Nails, an industrial rock band fronted by Trent Reznor, has toured all over the world since its creation in 1988. While Reznor—the only official member until adding Atticus Ross in 2016—controls its creative and musical direction in the studio, the touring band performs different arrangements of the songs. In addition to regular concerts, the band has performed in both supporting and headlining roles at festivals such as Woodstock '94, Lollapalooza 1991 and 2008, and many other one-off performances including the MTV Video Music Awards. Prior to their 2013 tour, the band had played 938 gigs.Nine Inch Nails' live performances contrast with its in-studio counterpart.
Reznor writes and performs nearly all Nine Inch Nails studio material, with occasional instrumental and vocal contributions from others artists. However, Reznor has typically assembled groups of backing musicians to interpret songs for tours and other live performances. Keyboardist Alessandro Cortini said that "if you see the show and you're used to the CDs it's pretty clear that the studio entity is different from the live entity".The only constant member of the live band is Reznor.  Live Nine Inch Nails performances are typically accompanied by lighting, stage, and video projection effects. Since 1999, the visual design components of live shows have been curated by Reznor with Rob Sheridan. Three tours have been chronicled on live albums and tour documentaries.
Critical and commercial response to Nine Inch Nails live performances has generally been positive. Critics have pointed to the concerts' aggressive on-stage dynamic and visual designs as high points. Reznor decided in 2008 to cease touring with the band after a 2009 farewell tour. The band resumed touring in 2013, with the group planning a set of concerts in the U.S. beginning September 28. 
Question: What's the full name of the man who was the only official member of Nine Inch Nails until 2016?

Answer: Trent Reznor.


Question: Passage: After two more EPs on Kompakt, the Orb (now composed of only Paterson and Fehlmann) released Okie Dokie It's The Orb on Kompakt, which featured new material in addition to tweaked versions of their previous Kompakt output. By this stage, Allmusic observed, Thomas Fehlmann had become the primary creative figure in the Orb, "inhibiting Alex Paterson's whimsical impulses". Because of this, Okie Dokie was considerably more focused and less "goofy" than Cydonia and Bicycles & Tricycles. Fehlmann's trademark hypnotic loops and delays made him the centre of Okie Dokie production and, according to Pitchfork Media, made it "difficult to say where [Paterson] is in the picture". The Orb's releases with Kompakt gained them back much of their musical credibility with the press and showed that they could "age gracefully".In August 2006, the founders of the Orb - Paterson and Cauty - released Living in a Giant Candle Winking at God, their debut album as the Transit Kings with Guy Pratt and Pratt's associate, Dom Beken. The album featured appearances from Smiths' guitarist Johnny Marr and comedian Simon Day. Beken described Living in a Giant Candle Winking at God as "self-consciously musically written and less sample-based" compared to the members' previous work. Living had been in production since 2001, but due to members' other obligations, it was delayed for several years. The album received mixed critical reactions, with reviewers such as The Sun comparing the album favourably to the music of DJ Shadow and Röyksopp while other publications, such as The Times, called it "Orb-lite" and proclaimed it to be "Deep Forest-style sludge". Soon after the album's release, Cauty left the Transit Kings on "extended leave", leaving the project in indefinite limbo. Paterson and Beken reunited in 2008 as High Frequency Bandwidth, an ambient hip hop group on the Malicious Damage label. 
Question: What is the first name of the person who it was said was difficult to say where he was in the picture?

Answer: Alex.


Question: Passage: The geography and ecology of the Everglades involve the complex elements affecting the natural environment throughout the southern region of the U.S. state of Florida. Before drainage, the Everglades were an interwoven mesh of marshes and prairies covering 4,000 square miles (10,000 km2). The Everglades is simultaneously a vast watershed that has historically extended from Lake Okeechobee 100 miles (160 km) south to Florida Bay (around one-third of the southern Florida peninsula), and many interconnected ecosystems within a geographic boundary. It is such a unique meeting of water, land, and climate that the use of either singular or plural to refer to the Everglades is appropriate. When Marjory Stoneman Douglas wrote her definitive description of the region in 1947, she used the metaphor "River of Grass" to explain the blending of water and plant life.
Although sawgrass and sloughs are the enduring geographical icons of the Everglades, other ecosystems are just as vital, and the borders marking them are subtle or nonexistent. Pinelands and tropical hardwood hammocks are located throughout the sloughs; the trees, rooted in soil inches above the peat, marl, or water, support a variety of wildlife. The oldest and tallest trees are cypresses, whose roots are specially adapted to grow underwater for months at a time. The Big Cypress Swamp is well known for its 500-year-old cypresses, though cypress domes can appear throughout the Everglades. As the fresh water from Lake Okeechobee makes its way to Florida Bay, it meets salt water from the Gulf of Mexico; mangrove forests grow in this transitional zone, providing nursery and nesting conditions for many species of birds, fish, and invertebrates. The marine environment of Florida Bay is also considered part of the Everglades because its sea grasses and aquatic life are attracted to the constant discharge of fresh water.
These ecological systems are always changing due to environmental factors. Geographic features such as the Western Flatwoods, Eastern Flatwoods, and the Atlantic Coastal Ridge affect drainage patterns. Geologic elements, climate, and the frequency of storms and fire are formative processes for the Everglades. They help to sustain and transform the ecosystems in the Shark River Valley, Big Cypress Swamp, coastal areas and mangrove forests. Ecosystems have been described as both fragile and resilient. Minor fluctuations in water levels have far-reaching consequences for many plant and animal species, and the system cycles and pulses with each change. 
Question: What type of system does minor fluctuations in water levels have far-reaching consequences for?

Answer:
Ecosystems.
