PROBLEM: Passage: A tropical disturbance moved westward offshore Nicaragua and was declared Tropical Depression Twenty-Four on October15.. During the early afternoon of the next day, ship reports indicated the formation of a tropical depression close to land. The cyclone moved at a quick pace towards the west-northwest south of a warm-core ridge. Early on the morning on October16, Roslyn became a tropical storm. By the morning of the October17, Roslyn had developed into a hurricane south of Acapulco. A vigorous upper trough was deepening offshore Baja California, and Roslyn began to re-curve within a few hundred miles of Manzanillo. The system struck Mazatlan as a marginal hurricane on October20. The low-level center rapidly dissipated, although a frontal low developed in the western Gulf of Mexico, which moved over southeastern Texas and later through the Mississippi Valley. The original upper-level circulation maintained its northeast movement, bringing rainfall to the Southeastern United States.
Link Information: none Question: What is the average temperature of the body of water where the frontal low developed?

SOLUTION: Answer: none

PROBLEM: Passage: White sharks also attack dolphins and porpoises from above, behind or below to avoid being detected by their echolocation. Targeted species include dusky dolphins (Lagenorhynchus obscurus), Risso's dolphins (Grampus griseus), bottlenose dolphins (Tursiops ssp.), Humpback dolphins (Sousa ssp.), harbour porpoises (Phocoena phocoena), and Dall's porpoises (Phocoenoides dalli). Groups of dolphins have occasionally been observed defending themselves from sharks with mobbing behaviour. White shark predation on other species of small cetacean has also been observed. In August 1989, a juvenile male pygmy sperm whale (Kogia breviceps) was found stranded in central California with a bite mark on its caudal peduncle from a great white shark. In addition, white sharks attack and prey upon beaked whales. Cases where an adult Stejneger's beaked whale (Mesoplodon stejnegeri), with a mean mass of around , and a juvenile Cuvier's beaked whale (Ziphius cavirostris), an individual estimated at , were hunted and killed by great white sharks have also been observed. When hunting sea turtles, they appear to simply bite through the carapace around a flipper, immobilizing the turtle. The heaviest species of bony fish, the oceanic sunfish (Mola mola), has been found in great white shark stomachs.
Link Information: largest dusky dolphins have been encountered off the coast of Peru, where they are up to 210cm (6feet) in length Question: Which of the dolphin and porpoise species that the great white sharks attack is the largest?

SOLUTION:
Answer: bottlenose dolphin
