TASK DEFINITION: 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 (", ").
PROBLEM: Paragraph- Sent 1: Roberta Adams skipped the thick how-to guide on child-custody forms and sat down at a computer at the Lamoreaux Justice Center in Orange on Wednesday.
Sent 2: The Garden Grove woman answered a series of questions to create and print a form to file with the court.
Sent 3: "It's easy," said Adams, 25.
Sent 4: "I thought I'd have all kinds of questions and have to take the forms home."Sent 5: A University of California, Irvine, study released Wednesday found an interactive computer system effectively helps people fill out paperwork for restraining orders, eviction defense, small-claims cases and requests for filing-fee waivers.
Sent 6: Not only does the system make life easier for people who can't afford a lawyer, but it also might improve efficiency in the courts because the forms, which are printed out when completed, are easy to read and are being filled out correctly, the study found.
Sent 7: Since the program started in 2000, more than 6,000 people have used the free system, located in public buildings throughout Orange County.
Sent 8: The system was developed by the Legal Aid Society of Orange County with about $800,000 in grants.
Sent 9: The program avoids legal jargon, offers a courthouse video tour and sticks to a fifth-grade vocabulary.
Sent 10: Users can choose English, Spanish or Vietnamese.
Sent 11: Kiosks are in courthouses in Fullerton and Orange, the district attorney's family-support office, the Legal Aid Society in Santa Ana, Irvine City Hall and the San Juan Capistrano Library.
Sent 12: The program is also available online.
Sent 13: Bob Cohen, executive director of Legal Aid, said the study should clear the way for expansion throughout California.
Sent 14: Locally, a program for divorce petitions will be added this summer.
Sent 15: Cohen said the system proves the benefit of technology tailored to those who aren't computer-savvy.
Sent 16: He said much of the technology now available requires Internet skills and access.
Sent 17: Low-income people, however, have less access to computers and less experience using them.
Sent 18: "Our clients have to catch up, and they have to become a part of the mainstream," Cohen said.
Question: Who thought that they would have all kinds of questions and have to take child-custody forms home?.

Sent 2: The map shows the Pacific island nation of Palau in relation to China.
Sent 3: Details of the transfer are still being worked out, Ambassador Hersey Kyota told CNN.

Sent 5: U.S. State Department spokesman Ian Kelly would not comment on the announcement, telling reporters, "We're still involved in ongoing discussions."Sent 6: The agreement includes some U.S. aid for Palau, Kyota said, but he said those details remained to be worked out as well.

Sent 8: Palau has received nearly $900 million in U.S. aid since independence in 1994, according to congressional auditors, and depends on Washington for defense.
Sent 9: The "Compact of Free Association" between Palau and the United States is up for review, but Kelly said any additional aid offer "is not linked to any other discussions we may be having with the government of Palau."Sent 10: The Uighurs were accused of receiving weapons and military training in Afghanistan.

Sent 4: How can this be?
Sent 5: Think about some common things we do.

Sent 8: Without rubber tires, the car would slide around.
Sent 9: Think about the bottom of your bathtub.
Sent 10: Do you have tape that has a sandy texture?
Sent 11: Maybe you use a rubber mat.
Sent 12: Both materials prevent you from slipping.
Sent 13: If you live in a really cold place, you have probably seen icy sidewalks.
Sent 14: Perhaps you have put sand on the frozen surface.
Sent 15: The sand increases friction.
Sent 16: It helps to keep you from slipping and falling.
Sent 17: Is friction always a good thing?
Sent 18: Too much friction can also be harmful.
Question: What can be done to prevent falls on icy sidewalks?.
