You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

Input: Consider Input: Paragraph- Sent 1: The Federal Aviation Administration (FAA) within the Department of Transportation had been vested by Congress with the sometimes conflicting mandate of regulating the safety and security of U.S. civil aviation while also promoting the civil aviation industry.
Sent 2: The FAA had a security mission to protect the users of commercial air transportation against terrorism and other criminal acts.
Sent 3: In the years before 9/11, the FAA perceived sabotage as a greater threat to aviation than hijacking.
Sent 4: First, no domestic hijacking had occurred in a decade.
Sent 5: Second, the commercial aviation system was perceived as more vulnerable to explosives than to weapons such as firearms.
Sent 6: Finally, explosives were perceived as deadlier than hijacking and therefore of greater consequence.
Sent 7: In 1996, a presidential commission on aviation safety and security chaired by Vice President Al Gore reinforced the prevailing concern about sabotage and explosives on aircraft.
Sent 8: The Gore Commission also flagged, as a new danger, the possibility of attack by surface-to-air missiles.
Sent 9: Its 1997 final report did not discuss the possibility of suicide hijackings.
Sent 10: The FAA set and enforced aviation security rules, which airlines and airports were required to implement.
Sent 11: The rules were supposed to produce a "layered" system of defense.
Sent 12: This meant that the failure of any one layer of security would not be fatal, because additional layers would provide backup security.
Sent 13: But each layer relevant to hijackings-intelligence, passenger prescreening, checkpoint screening, and onboard security-was seriously flawed prior to 9/11.
Sent 14: Taken together, they did not stop any of the 9/11 hijackers from getting on board four different aircraft at three different airports.
Sent 15: The FAA's policy was to use intelligence to identify both specific plots and general threats to civil aviation security, so that the agency could develop and deploy appropriate countermeasures.
Sent 16: The FAA's 40-person intelligence unit was supposed to receive a broad range of intelligence data from the FBI, CIA, and other agencies so that it could make assessments about the threat to aviation.
Sent 17: But the large volume of data contained little pertaining to the presence and activities of terrorists in the United States.
Sent 18: For example, information on the FBI's effort in 1998 to assess the potential use of flight training by terrorists and the Phoenix electronic communication of 2001 warning of radical Middle Easterners attending flight school were not passed to FAA headquarters.
Question: What was the problem with the layered security system in place by the FAA?.

Input: Consider Input: Paragraph- Sent 1: (CNN) -- Beyond skateboards, Silicon Valley and hippies, California has a trendsetting streak of a different kind.
Sent 2: The state has been first to pass major public health initiatives that have spread throughout the country.
Sent 3: California was first to require smog checks for clean air, pass anti-tobacco initiatives and bike helmets laws.
Sent 4: While these laws were met with skepticism and ridicule, they've often become standard practice in other states.
Sent 5: The Golden State was first to ban smoking in workplaces, bars and restaurants in 1998.
Sent 6: Now similar rules exist throughout the country.
Sent 7: Some advocates tout the state as a forward-thinking vanguard in which its health and safety laws are routinely emulated by other states.
Sent 8: "There have been progressive legislations in tobacco, environment and obesity prevention," said Mark Horton, a lecturer at the University of California Berkeley School of Public Health.
Sent 9: "In some respect, the rest of the country looks to California as a laboratory for moving forward with those various types of initiatives."Sent 10: But some critics liken the Golden State to a nanny state.
Sent 11: California has 151,002 health and safety laws.
Sent 12: "It never ends," said Laer Pearce, who works in public affairs in Orange County.
Sent 13: "Every year, several hundred bills come through and dozens of them tell us how to live our lives."Sent 14: Starting in January, 760 new California laws went into effect -- for example, the importing of shark fins is prohibited, student athletes are required to have medical clearance after suffering a head injury, teens are banned from using tanning booths and the sale of caffeinated beer is forbidden.
Sent 15: There's a perception that California has "more folks who are health-oriented and more health-minded," said Horton, former director of the California Department of Public Health.
Sent 16: It's not just workout fanatics hanging out at Muscle Beach, Sierra Club members hiking mountains or the uber-health-conscious touting organic foods.
Sent 17: Californians in general tend to have healthier habits, ranking 10th for physical activity, fourth for healthy blood pressure and fifth for a diet high in fruits and vegetables compared with other states, according to America's Health Rankings.
Question: Why do some critics call California the nanny state?.
