Listen to each assistant's responses to the following instruction, and give each a score out of 100 and an explanation for the score. Here are some additional guidelines: * Do not award bonus points. * If the instruction includes additional context from which the response should be generated, deduct points if the response includes details not found within the provided context. * The assistants should not be making assumptions about the intent of the question. * If the instruction asks for results in a specific format, e.g. JSON, 50% of the score should be whether or not the assistant produced the correct format. * Award points for effort and problem formulation when the instruction is related to solving mathematical equations or coding. Respond in format "[assistant number]. [score]/100 - [explanation] Instruction: According to the text, what year was the first successful human heart transplant performed? The Eurasian lynx (Lynx lynx) is a medium-sized wild cat native to the forests of Europe and Asia. This elusive predator is known for its distinctive ear tufts, which can grow up to 4 centimeters in length, and its short tail, which measures around 25 centimeters on average. The species' coat varies in color from reddish-brown to gray, with darker spots and stripes that provide camouflage in their forested habitat. Eurasian lynxes are solitary animals, with males and females only coming together during the mating season, which occurs between January and April. Females give birth to one to four kittens after a gestation period of approximately 67 days. These kittens remain with their mother for about ten months before venturing out on their own. As carnivorous mammals, the diet of the Eurasian lynx primarily consists of small ungulates such as roe deer, chamois, and reindeer. However, they have also been known to prey on smaller mammals like hares, rodents, and birds when larger prey is scarce. Their excellent night vision and stealthy hunting techniques make them efficient predators within their ecosystem. Although the Eurasian lynx has no natural predators, it faces threats from habitat loss, poaching, and declining prey populations. Conservation efforts are currently underway to protect this species and maintain healthy population levels. In some regions, reintroduction programs have been successful in reestablishing the presence of these elusive cats. Assistant 1's response: The text does not provide information about the first successful human heart transplant performed. Assistant 2's response: The text does not provide any information about the year the first successful human heart transplant was performed. Assistant 3's response: The first successful human heart transplant was performed in 1967. Assistant 4's response: The first successful human heart transplant was performed on December 3, 1967, by a team of surgeons led by Dr. Christiaan Barnard in Cape Town, South Africa. The recipient of the transplant, Louis Washkansky, lived for 18 days after the operation before succumbing to pneumonia. Assistant 5's response: The first successful human heart transplant was performed in 1967. Assistant 6's response: According to the text, the first successful human heart transplant was performed in 1967 by Dr. Christiaan Barnard in Cape Town, South Africa.
