input: Please answer the following: Given the following context:  Joe Hickey, his wife Cheryl and his cousin Marvin have developed a money-making scheme – they kidnap the child of rich parents, hold the child for 24 hours and demand ransom money from the father. They each have a specific role in the operation – Marvin kidnaps the child, Joe stays in the victims' house to control the mother, and Cheryl deals with the father.  Dr. Will Jennings is a research physician who has just had his big career break by patenting a new anesthetic drug. His wife, Karen Jennings, who was previously a nurse, is a stay-at-home mother to their daughter Abigail, aka Abby (Dakota Fanning). Joe targets Abigail as the next kidnapping victim and the trio begin to enact their usual plan. Abby is kidnapped by Joe and Marvin and they soon discover that she has asthma and is dependent on an inhaler pump. Marvin takes Abby to his cabin and Joe holds Karen hostage. Cheryl keeps Will at gunpoint and informs him of his daughter's kidnapping. It is subsequently revealed that Cheryl and Joe kidnapped Abby because they believe that Will is responsible for the recent death of their daughter Katie: Katie had a tumor and died while being operated on by Will. Will reveals that Katie died because of unforeseen bleeding accidentally caused by the head surgeon during the operation; the surgeon then lied to Joe and Cheryl, convincing them that Katie's death was as a result of negligence by Will in Katie's recovery to avoid scrutiny by them. It is revealed that Joe's real plan is not to let Abby go home after the ransom is paid, but rather, to keep her and raise her as his own daughter.  answer the following question:  Who actually caused the death of Joe's daughter?
++++++++++
output: the head surgeon


input: Please answer the following: Given the following context:  The newspaper Aftonbladet had supplied the pigeons, bred in northern Norway with the optimistic hope that they would manage to return there, and their message cylinders contained pre-printed instructions in Norwegian asking the finder to pass the messages on to the newspaper's address in Stockholm. Andrée released at least four pigeons, but only one was ever retrieved, by a Norwegian steamer where the pigeon had alighted and been promptly shot. Its message is dated 13 July and gives the travel direction at that point as East by 10° South. The message reads: "The Andree Polar Expedition to the "Aftonbladet", Stockholm. 13 July, 12.30 p.m., 82 deg. north latitude, 15 deg. 5 min. east longitude. Good journey eastwards, 10 deg. south. All goes well on board. This is the third message sent by pigeon. Andree." Lundström and others note that all three messages fail to mention the accident at takeoff, or the increasingly desperate situation, which Andrée described fully in his main diary. The balloon was out of equilibrium, sailing much too high and thereby losing hydrogen faster than even Nils Ekholm had feared, then repeatedly threatening to crash on the ice. It was weighed down by being rain-soaked ("dripping wet", writes Andrée in the diary), and the men were throwing all the sand and some of the payload overboard to keep it airborne. Free flight lasted for 10 hours and 29 minutes and was followed by another 41 hours of bumpy riding with frequent ground contact before the inevitable final crash. The Eagle traveled for two days and three-and-a-half hours altogether, during which time, according to Andrée, none of the three men got any sleep. The definitive landing appears to have been gentle. Neither the men nor the homing pigeons in their wicker cages were hurt, and none of the equipment was damaged, not even the delicate optical instruments and Strindberg's two cameras.  answer the following question:  What was the name of the item that was in an accident at takeoff?
++++++++++
output: The Eagle


input: Please answer the following: Given the following context:  The Chicxulub crater (; Mayan: [tʃʼikʃuluɓ]) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter, the Chicxulub impactor, striking the Earth. The date of the impact coincides precisely with the Cretaceous–Paleogene boundary (K–Pg boundary), slightly less than 66 million years ago, and a widely accepted theory is that worldwide climate disruption from the event was the cause of the Cretaceous–Paleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs. The crater is estimated to be 150 kilometres (93 miles) in diameter and 20 km (12 mi) in depth, well into the continental crust of the region of about 10–30 km (6.2–18.6 mi) depth. It is the second largest confirmed impact structure on Earth and the only one whose peak ring is intact and directly accessible for scientific research.The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatán during the late 1970s. Penfield was initially unable to obtain evidence that the geological feature was a crater and gave up his search. Later, through contact with Alan Hildebrand in 1990, Penfield obtained samples that suggested it was an impact feature. Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas. In 2016, a scientific drilling project drilled deep into the peak ring of the impact crater, hundreds of meters below the current sea floor, to obtain rock core samples from the impact itself. The discoveries were widely seen as confirming current theories related to both the crater impact and its effects.  answer the following question:  What are the full names of the people that discovered the Chicxulub crater?
++++++++++
output:
Antonio Camargo
