[EX Q]: Passage: Sherman 'Tank' Turner is a help line operator and a ladies man with a hobby: If a guy loses a girl and wants her back, he gets in touch with Tank and pays him to take the girl on a bad date.  Throughout the evening Tank inevitably behaves in the most moronic fashion causing the girl to realize that her ex was not really such a bad guy after all and get back to their ex.
He shares an apartment with his step cousin Dustin who has fallen for his colleague Alexis. Dustin takes Alexis on a date and confesses his love but she insists they remain friends. After the date Dustin explains his situation to Tank who volunteers his services as a good friend (instead of having to pay for his services as usual). Dustin initially turns him down, not wanting Tank to be close to Alexis, but the next day sees Alexis flirting with another co-worker and begs Tank to take Alexis out. He accepts.
Tank bumps into Alexis and they arrange to go out.  He behaves badly all night but Alexis is too drunk to care. When he drops her off she expects him to come in but he resists the temptation out of loyalty to Dustin. Alexis calls Dustin but when they meet she explains that her date with Tank has motivated her to see other men.  Dustin sends Alexis roses and an apology poem in Tank's name. Alexis calls Tank at work and berates him for leaving early the previous night.  Tank goes to see Alexis and they end up having casual sex on a regular basis while Dustin begins a series of desperate attempts to stay friends with her after all. 
Question: What is the alias of the person who volunteers his services to his cousin?
[EX A]: Tank.

[EX 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?
[EX A]: Ecosystems.
