Question: When was Clements High School established? Passage:KJ Noons is hapa kanaka, hapa haole—mixed ethnicity of native Hawaiian (from his mother's side) and European-American (from his father's side). Born and raised in Kailua-Kona, Hawaii, Noons comes from a family history of fighting. His father Karl was a professional kickboxer and was a top contender during the time he fought. Karl's passion for fighting and competing in combat sports influenced him to introduce his son to martial arts at a young age. At the age of five, Noons started training in Kenpō Karate. Often getting disqualified for fighting too hard in karate tournaments, Noons eventually started training in boxing and Muay Thai at the age of eight out of interest for full contact fighting. Noons competed as an amateur fighter and became the first student in the state of Hawaii to earn a junior black belt under Ed Parker at the age of 11. During his high school years, Noons moved to Houston, Texas due to the location of his father's job. While continuing to compete as a fighter, he also started playing football at Clements High School. At age 17, Noons won the ISKA Super Middleweight International Championship as an amateur in Sanshou. After winning the title and graduating from Clements High School, K.J. decided to pursue a career in combat sports, rather than go to college and continue with football.

Question: Which of the dolphin and porpoise species that the great white sharks attack is the largest? 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.
