Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Another letter to The New York Times blamed the shark infestation on the maneuvers of German U-boats near America's East Coast. The anonymous writer claimed, "These sharks may have devoured human bodies in the waters of the German war zone and followed liners to this coast, or even followed the Deutschland herself, expecting the usual toll of drowning men, women, and children." The writer concluded, "This would account for their boldness and their craving for human flesh."Decades later, there is no consensus among researchers over Murphy and Lucas's investigation and findings. Richard G. Fernicola published two studies of the event, and notes that "there are many theories behind the New Jersey attacks," and all are inconclusive. Researchers such as Thomas Helm, Harold W. McCormick, Thomas B. Allen, William Young, Jean Campbell Butler, and Michael Capuzzo generally agree with Murphy and Lucas. However, the National Geographic Society reported in 2002 that "some experts are suggesting that the great white may not in fact be responsible for many of the attacks pinned on the species. These people say the real culprit behind many of the reported incidents—including the famous 1916 shark attacks in New Jersey that may have served as inspiration for Jaws—may be the lesser known bull shark."Biologists George A. Llano and Richard Ellis suggest that a bull shark could have been responsible for the fatal Jersey Shore attacks. Bull sharks swim from the ocean into freshwater rivers and streams and have attacked people around the world. In his book Sharks: Attacks on Man (1975), Llano writes,
One of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea. Elsewhere in the book are accounts of well-documented shark-human interactions at Ahwaz, Iran, which is 90 miles (140 km) upriver from the sea. It may also be of interest to note that sharks live in Lake Nicaragua, a fresh-water body, and in 1944 there was a bounty offered for dead freshwater sharks, as they had "killed and severely injured lake bathers recently."
Ellis points out that the great white "is an oceanic species, and Schleisser's shark was caught in the ocean. To find it swimming in a tidal creek is, to say the least, unusual, and may even be impossible. The bull shark, however, is infamous for its freshwater meanderings, as well as for its pugnacious and aggressive nature."  He admits that "the bull shark is not a common species in New Jersey waters, but it does occur more frequently than the white."In an interview with Michael Capuzzo, ichthyologist George H. Burgess surmises, "The species involved has always been doubtful and likely will continue to generate spirited debate." Burgess, however, does not discount the great white:.
What is the first name of the person who said one of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea?
