Question: Paragraph: In the interview, Bolsonaro also stuck to the government's assertion that a Greek freighter caused the oil spill scattered across beaches along 1,300 miles (2,100 kilometers) of coastline even after the shipowner's denial of any leakage from its vessel. "All signs point to this Greek cargo ship. All of them," he told Record TV, adding that the leak, "by all accounts looks like it was criminal." Brazil's government has been striving to investigate the cause of the spill that has hit 321 beaches along the northeast coast since early September, hurting fishing and tourism. Authorities have described the spill as one of the country's worst environmental disasters. The crude's density renders it invisible from above, making it hard to track its origin or to have a clear picture of the amount of oil yet to reach Brazil's coast. Some 4,000 tons of oil has been collected from northeastern beaches thus far, according to a statement Sunday from the Navy, Brazil's environmental regulator, and the national petroleum agency. "To say how much oil there still is very difficult to say," Commander Leonardo Puntel of the Brazilian Navy said at a press conference on Monday. "Since the oil is underwater, we don't know if there's still a lot or a little. There is effectively no correct and accurate way to monitor these oil spots," he said, adding that they have seen a decrease in oil arriving onto beaches in recent days. He called the disaster "unprecedented." "There is no case in the world of a large-scale oil spill where the origins are totally unknown. This case has no parallel, we don't know who polluter is," Puntel said. Brazil's defense minister, Gen. Fernando Azevedo e Silva, also stressed how challenging it is to calculate the spill's scope. "It is not detectable by satellite. ... It is imperceptible. We do not know how much will still come," he said. David Zee, an oceanographer at the State University of Rio de Janeiro, said that the 4,000 tons of collected oil is "just the tip of the iceberg," both because the cleanup effort is mostly limited to sandy beaches in populated areas and also because a large portion of spilled oil is likely spread deep beneath the ocean's surface. Furthermore, when currents bring oil to sandy shores, it is relatively easy to collect, while is nearly impossible to remove from corals and mangrove forests, which make up part of the affected area, Zee said. Brazilian prosecutors have named Greek shipping company Delta Tankers Ltd as a suspect of the leak's origins. The company issued a statement earlier saying it found no evidence of leakage after reviewing the ship's cameras and sensors. "This material will be willingly shared with Brazilian authorities, should they contact the company regarding this investigation. So far, no such contact has been made," the statement said. Federal Police officer Franco Perazzoni said at Monday's press conference that the company will be officially notified via Interpol. Brazilian prosecutors said previously that Delta's oil tanker, named Bouboulina, was navigating through Brazilian waters at the time and location of the spill. The ship was carrying oil from Venezuela to Malaysia. In a search order seen Friday by The Associated Press, Brazilian prosecutors said "there is no indication of another boat" that could have discharged the Venezuelan crude into the sea. Brazilian armed forces along with environmental protection agencies and petroleum authorities are leading an operation to clean, monitor and investigate the oil spill. Several public universities are conducting research about the spill's origins and impact. Television footage has also shown volunteers flocking to beaches to help with the cleanup, often without government supervision. Of particular concern at the moment is the Abrolhos national marine park, home to Brazil's largest coral reefs. Authorities said Sunday night that they had removed the fragments of oil that had appeared in the park and so far no new traces had been found. "A very small amount of oil arrived on November 2, on November 3 only a few fragments remained, today there's none," Puntel said in the Monday press conference. "Will more oil fragments come? Maybe." Claim: Brazil reckons with new oil spill mystery: When will it end?.

Answer: Brazilian authorities said on Monday that they have no way of knowing how much more oil will wash ashore the country's northeastern coast, despite President Jair Bolsonaro's ominous warning during a Sunday night TV interview that "the worst is yet to come."

Question: Paragraph: The Miami-based hurricane center issued a tropical storm warning for islands including hurricane-hit Abacos and Grand Bahama, saying the system could become a tropical depression or storm before making landfall as early as Friday. Hurricane Dorian slammed into the Bahamas on Sept. 1 as a Category 5 storm, one of the strongest Atlantic hurricanes on record to hit land, packing top sustained winds of 185 miles per hour (298 km per hour). The tropical cyclone was not expected to bring anywhere near that level of devastation, but was capable of winds of 30 miles per hour and 2 to 4 inches of rain through Sunday, according to the hurricane center. Aid groups rushed shelter material to residents living in the shells of former homes or whose homes had been stripped of their roofs. "We're seeing plastic tarps go out all over the islands, and that's extremely important because now you've got another tropical storm coming," said Ken Isaacs, vice president of programs for U.S. relief organization Samaritan's Purse. The prime minister of the Bahamas, Hubert Minnis, on Wednesday said the official death toll was 50 but was expected to rise. Former Prime Minister Hubert Ingraham said he believed "hundreds" were dead on Abaco "and significant numbers on Grand Bahama," the Nassau Guardian newspaper reported on Thursday. Minnis said there were problems coordinating aid due to the level of devastation and he was trying to remove "bureaucratic roadblocks." With 1,300 people still missing, according to the Bahamian government, relief services are focused on search and rescue as well as providing life-sustaining food, water and shelter. Officials have erected large tents in Nassau to house those made homeless by Dorian and plan to erect tent cities on Abaco capable of sheltering up to 4,000 people. A flood of aid has caused bottlenecks at docks and airports, creating "a lot of delays" in relief supplies, said Nat Abu-Bonsrah of the Adventist Development and Relief Agency, the global humanitarian organization of the Seventh-day Adventist Church. Due to a shortage of functioning vehicles and facilities on Grand Bahama, the group turned to church members to lend their cars and kitchens for its program providing hot meals to over 400 people a day in Freeport. "We've not been able to reach them as much as we want," he said of efforts to get hundreds of hygiene kits to survivors. Groups like Samaritan's Purse, with their own aircraft or logistics chains, said they had not encountered issues with coordination or government red tape. "I think we're accomplishing our mission, any roadblocks we have right now are our own," said Dennis Clancey, a field operations manager for relief group Team Rubicon, which has deployed mobile medical units to treat patients. Claim: Tropical storm warning issued for Bahamas; 1,300 still missing.

Answer: A tropical cyclone was forecast to move across the northwestern Bahamas in the coming days, potentially bringing more rain and wind to islands already devastated by Hurricane Dorian, the U.S. National Hurricane Center warned on Thursday.

Question: Paragraph: The New Hampshire Department of Health and Human Services' Division of Public Health Services says the four people likely acquired Legionella at the end of July or beginning of August in a localized area of Hampton. Legionnaire's disease, also called Legionella pneumonia, is a bacterial pneumonia. The public health department says it is investigating for additional cases of the disease, as well as for the source of the infections. The disease is usual spread by inhaling droplets of water contaminated with the bacteria. Many people exposed to Legionella do not get sick. The disease has the ability to cause serious illness and death, however. Claim: 4 Legionnaire's cases originated in New Hampshire beach town.

Answer:
Public health authorities in New Hampshire say four people who have been identified with Legionnaire's disease likely acquired the disease in Hampton.
