Ans: Heike Kamerlingh Onnes
Ques: He next experimented with a high-pressure hydrogen jet by which low temperatures were realised through the Joule -- Thomson effect, and the successful results he obtained led him to build at the Royal Institution a large regenerative cooling refrigerating machine. Using this machine in 1898, liquid hydrogen was collected for the first time, solid hydrogen following in 1899. He tried to liquefy the last remaining gas, helium, which condenses into a liquid at − 268.9 ° C, but owing to a number of factors, including a short supply of helium, Dewar was preceded by Heike Kamerlingh Onnes as the first person to produce liquid helium, in 1908. Onnes would later be awarded the Nobel Prize in Physics for his research into the properties of matter at low temperatures -- Dewar was nominated several times, but never succeeded in winning the Nobel Prize.

Answer: season two. Now, what could be the question and solution-maybe?
Ques: Mark first appears in season two, introduced as a highly respected otolaryngologist sub-specialized in plastic surgery and the childhood best friend of neurosurgeon Derek Shepherd (Patrick Dempsey). Derek explains that Mark had an affair with his wife, Addison (Kate Walsh) while they were living in New York. Mark travels to Seattle, intent on convincing Addison to return with him, but his offer is rejected and Derek declines to renew their friendship. Mark returns during season three at Addison's drunken behest, but she again rejects him once sober. Undeterred, Mark sells his successful private practice (which he previously shared with Derek) and takes over the plastics program at Seattle Grace Hospital. During Meredith's morphine rampage, Mark finds out about his nickname McSteamy which was given to him by her during his first trip to Seattle back when he attempted to get Addison back and earn Derek's friendship back. It is later revealed that Mark has at some point slept with all of Derek's sisters. Mark has a brief fling with Addison's friend, orthopedic surgeon Callie Torres (Sara Ramirez), and develops a friendship with Derek's girlfriend, intern Meredith Grey (Ellen Pompeo). It is revealed that after Derek left New York, Mark and Addison continued their relationship for two months, during which she conceived and aborted his child. Just weeks after moving to Seattle he quickly observes that Derek's true love was Meredith and tries to convince Addison that her marriage with Derek was over. Mark enters into a sixty-day abstinence pact with Addison, agreeing that if they can remain celibate for that time, Addison will give their relationship another chance. Addison ultimately breaks the pact by having sex with intern Alex Karev (Justin Chambers), and soon thereafter departs from Seattle to work in Los Angeles.

Ans: competitive levels of organized hockey , with AAA being elite competition
Ques: Higher-skilled players will typically play on "representative" or "travel" teams that will travel to play representative (rep) teams from other areas. These teams are classified by skill. Not all cities will have teams at all skill levels, depending on size and the popularity of hockey, however even small communities may field teams at multiple levels. (For example: Orillia, Ontario, with a population of 30,000, has four distinct skill divisions for 7-year-olds.) The classifications are typically not certified by any external organization, so there is speculation about what levels are truly better or stronger than others. AAA, AA, and A hockey are nationally recognized as competitive levels of organized hockey, with AAA being elite competition. The competitive level players generally engage in high levels of physical play from a young age. This physical play can lead to injuries and most often these are related to the head. Injuries have become more prevalent as physical play has increased in the sport.
