Q: 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?

A: Ecosystems.

Q: Passage: When charter-boat skipper Jack O'Conner finds a gold Spanish dollar off the Florida Keys, he decides to go in search of a legendary hoard of Spanish doubloons sunk during the "Hundred Years Storm" of 1780. For, as Jack's friend Cap'n Billau reveals, the coin bears a clue to the treasure's whereabouts – one of four islands etched by the infamous pirate, Jacques Un-Oeil upon the original doubloon. At Billau's urging, Jack tracks down the two beautiful women who unknowingly hold the remaining clues.
Streetwise Sandy Sequoia's piece of eight came from her murdered drug dealer boyfriend in Miami. And lonely-heart Portia Pennington inherited her coin from her merchant tycoon grandfather, who died at sea in the "Hundred Years Storm" of 1893, while hunting for the lost gold.
Jack convinces the girls to go in search of the pirate treasure with him. But first, the two must learn to crew his 76' schooner; and then, all three adventurers must learn to trust one another, if they expect to navigate the treacheries of love and the unpredictable Caribbean.
As Jack introduces the girls to life at sea, he starts to fall in love with Sandy. All seems to be going well, until Jack discovers Sandy with drugs on his boat – a kilo of her dead boyfriend's cocaine (which she has steadily been using since coming aboard). He has Portia dump the coke overboard; and while Sandy wrestles to overcome her addiction, Jack turns his attentions to Portia.
When Sandy and Portia realize that Jack has seduced each of them in turn and convinced each to reveal to him the name of the island on her coin, they turn on him. Feeling betrayed and realizing that they no longer need Jack in order to sail the boat or find the gold, they maroon him on a small island and go after the sunken treasure themselves. 
Question: What are the first names of the people who Jack convinces to go in search of the treasure with him?

A: Sandy.

Q: Passage: Kill 'Em All is the debut studio album by the American heavy metal band Metallica, released on July 25, 1983, by the independent record label Megaforce Records. Kill 'Em All is regarded as a groundbreaking album for thrash metal because of its precise musicianship, which fuses new wave of British heavy metal riffs with hardcore punk tempos. The album's musical approach and lyrics were markedly different from rock's mainstream of the early 1980s and inspired a number of bands who followed in similar manner. The album did not enter the Billboard 200 until 1986, when it peaked at number 155, following Metallica's commercial success with its third studio album Master of Puppets; the 1988 Elektra reissue peaked at number 120. Kill 'Em All was critically praised at the time of its release and in retrospect, and was placed on a few publications' best album lists. It was certified 3× Platinum by the Recording Industry Association of America (RIAA) in 1999 for shipping three million copies in the United States. The album generated two singles, "Whiplash" and "Jump in the Fire".
Metallica began by playing shows in local clubs in Los Angeles. They recorded several demos to gain attention from club owners, and eventually relocated to San Francisco to secure the services of bassist Cliff Burton. The group's No Life 'til Leather demo tape (1982) was noticed by Megaforce label head Jon Zazula, who signed them and provided a budget of $15,000 for recording. The album was recorded in May with producer Paul Curcio at the Music America Studios in Rochester, New York. It was originally intended to be titled Metal Up Your Ass, with cover art featuring a hand clutching a dagger emerging from a toilet bowl. The band was asked to change the name because distributors feared that releasing an album with such an offensive title and artwork would diminish its chances of commercial success. Metallica promoted the album on the two-month co-headlining Kill 'Em All for One tour with English heavy metal band Raven in the U.S. Although the initial shipment was 15,000 copies in the U.S., the album sold 60,000 copies worldwide by the end of Metallica's Seven Dates of Hell European tour in 1984. 
Question: What album was reissued?

A:
Kill 'Em All.
