In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Q: Passage: Another letter to The New York Times blamed the shark infestation on the maneuvers of German U-boats near America's East Coast. The anonymous writer claimed, "These sharks may have devoured human bodies in the waters of the German war zone and followed liners to this coast, or even followed the Deutschland herself, expecting the usual toll of drowning men, women, and children." The writer concluded, "This would account for their boldness and their craving for human flesh."Decades later, there is no consensus among researchers over Murphy and Lucas's investigation and findings. Richard G. Fernicola published two studies of the event, and notes that "there are many theories behind the New Jersey attacks," and all are inconclusive. Researchers such as Thomas Helm, Harold W. McCormick, Thomas B. Allen, William Young, Jean Campbell Butler, and Michael Capuzzo generally agree with Murphy and Lucas. However, the National Geographic Society reported in 2002 that "some experts are suggesting that the great white may not in fact be responsible for many of the attacks pinned on the species. These people say the real culprit behind many of the reported incidents—including the famous 1916 shark attacks in New Jersey that may have served as inspiration for Jaws—may be the lesser known bull shark."Biologists George A. Llano and Richard Ellis suggest that a bull shark could have been responsible for the fatal Jersey Shore attacks. Bull sharks swim from the ocean into freshwater rivers and streams and have attacked people around the world. In his book Sharks: Attacks on Man (1975), Llano writes,
One of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea. Elsewhere in the book are accounts of well-documented shark-human interactions at Ahwaz, Iran, which is 90 miles (140 km) upriver from the sea. It may also be of interest to note that sharks live in Lake Nicaragua, a fresh-water body, and in 1944 there was a bounty offered for dead freshwater sharks, as they had "killed and severely injured lake bathers recently."
Ellis points out that the great white "is an oceanic species, and Schleisser's shark was caught in the ocean. To find it swimming in a tidal creek is, to say the least, unusual, and may even be impossible. The bull shark, however, is infamous for its freshwater meanderings, as well as for its pugnacious and aggressive nature."  He admits that "the bull shark is not a common species in New Jersey waters, but it does occur more frequently than the white."In an interview with Michael Capuzzo, ichthyologist George H. Burgess surmises, "The species involved has always been doubtful and likely will continue to generate spirited debate." Burgess, however, does not discount the great white:. 
Question: What is the full name of the book with accounts of well-documented shark-human interactions at Ahwaz, Iran?

A: Sharks: Attacks on Man.

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: Immediately after Aaliyah's death, there was uncertainty over whether the music video for "Rock the Boat" would ever air. It made its world premiere on BET's Access Granted on October 9, 2001. She won two posthumous awards at the American Music Awards of 2002; Favorite Female R&B Artist and Favorite R&B/Soul Album for Aaliyah. Her second and final film, Queen of the Damned, was released in February 2002. Before its release, Aaliyah's brother, Rashad, re-dubbed some of her lines during post-production. It grossed US$15.2 million in its first weekend, ranking number one at the box office. On the first anniversary of Aaliyah's death, a candlelight vigil was held in Times Square; millions of fans observed a moment of silence; and throughout the United States, radio stations played her music in remembrance. In December 2002, a collection of previously unreleased material was released as Aaliyah's first posthumous album, I Care 4 U. A portion of the proceeds was donated to the Aaliyah Memorial Fund, a program that benefits the Revlon UCLA Women's Cancer Research Program and Harlem's Sloan Kettering Cancer Center. It debuted at number three on the Billboard 200, selling 280,000 copies in its first week. The album's lead single, "Miss You", peaked at number three on the Billboard Hot 100 and topped the Hot R&B/Hip-Hop Songs chart. In August of the following year, clothing retailer Christian Dior donated profits from sales in honor of Aaliyah.In 2005, Aaliyah's second compilation album, Ultimate Aaliyah was released in the UK by Blackground Records. Ultimate Aaliyah is a three disc set, which included a greatest hits audio CD and a DVD. Andy Kellman of AllMusic remarked "Ultimate Aaliyah adequately represents the shortened career of a tremendous talent who benefited from some of the best songwriting and production work by Timbaland, Missy Elliott, and R. Kelly." A documentary movie Aaliyah Live in Amsterdam was released in 2011, shortly before the tenth anniversary of Aaliyah's death. The documentary, by Pogus Caesar, contained previously unseen footage shot of her career beginnings in 1995 when she was appearing in the Netherlands.In March 2012, music producer Jeffrey "J-Dub" Walker announced on his Twitter account that a song "Steady Ground", which he produced for Aaliyah's third album, would be included in the forthcoming posthumous Aaliyah album. This second proposed posthumous album would feature this song using demo vocals, as Walker claims the originals were somehow lost by his sound engineer. Aaliyah's brother Rashad later refuted Walker's claim, claiming that "no official album [is] being released and supported by the Haughton family.". 
Question: "Miss You" was the lead single on which album?

A:
I Care 4 U.
