Task: Question Answering
Input (English): Passage: Laika was found as a stray wandering the streets of Moscow. Soviet scientists chose to use Moscow strays since they assumed that such animals had already learned to endure conditions of extreme cold and hunger. This specimen was a 5 kg (11 lb) mongrel female, approximately three years old. Another account reported that she weighed about 6 kg (13 lb). Soviet personnel gave her several names and nicknames, among them Kudryavka (Russian for Little Curly), Zhuchka (Little Bug), and Limonchik (Little Lemon). Laika, the Russian name for several breeds of dogs similar to the husky, was the name popularised around the world. The American press dubbed her Muttnik (mutt + suffix -nik) as a pun on Sputnik, or referred to her as Curly. Her true pedigree is unknown, although it is generally accepted that she was part husky or other Nordic breed, and possibly part terrier. NASA refers to Laika as a "part-Samoyed terrier." A Russian magazine described her temperament as phlegmatic, saying that she did not quarrel with other dogs. Vladimir Yazdovsky, who led the program of test dogs used on rockets, in a later publication wrote that “Laika was quiet and charming”.The Soviet Union and United States had previously sent animals only on sub-orbital flights. Three dogs were trained for the Sputnik 2 flight: Albina, Mushka, and Laika. Soviet space-life scientists Vladimir Yazdovsky and Oleg Gazenko trained the dogs.To adapt the dogs to the confines of the tiny cabin of Sputnik 2, they were kept in progressively smaller cages for periods of up to 20 days. The extensive close confinement caused them to stop urinating or defecating, made them restless, and caused their general condition to deteriorate. Laxatives did not improve their condition, and the researchers found that only long periods of training proved effective. The dogs were placed in centrifuges that simulated the acceleration of a rocket launch and were placed in machines that simulated the noises of the spacecraft. This caused their pulses to double and their blood pressure to increase by 30–65 torr. The dogs were trained to eat a special high-nutrition gel that would be their food in space.Before the launch, one of the mission scientists took Laika home to play with his children. In a book chronicling the story of Soviet space medicine, Dr. Vladimir Yazdovsky wrote, "Laika was quiet and charming...I wanted to do something nice for her: She had so little time left to live.". 
Question: What were the names of the three dogs that were trained to eat high-nutrition gel?
Output (English): Laika.
