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 (", ").

Q: Paragraph- Sent 1: Representing yourself in court can be a tricky endeavor.
Sent 2: There are confusing legal terms to learn, strict procedures to follow and volumes of case law that often need to be understood to prepare a case.
Sent 3: Lake County officials and a private agency that assists indigent litigants in Illinois want to make the practice easier by creating a self-help center for people who choose to represent themselves in legal matters.
Sent 4: The center, which will be housed in the law library at the main courthouse in Waukegan, could open later this summer.
Sent 5: "I think it's going to be extremely helpful," Court Administrator Bob Zastany said.
Sent 6: "There is a population out there that will take advantage of this resource."Sent 7: The self-help center will be the only one of its kind in the county.
Sent 8: Only a few operate nationwide, officials said.
Sent 9: The project is the work of Lake County circuit court officials and Prairie State Legal Services, a statewide agency with an office in Waukegan that provides information and legal assistance to poor and elderly Illinois residents.
Sent 10: The organization has received a $25,000 grant from the Illinois Equal Justice Foundation, a nonprofit group that funds programs designed to increase access to legal information and assistance, to help pay for the effort.
Sent 11: Prairie State will share the money with the county.
Sent 12: The county's law library is on the first floor of the governmental center at 18 N. County St. The new self-help center will be designed to help litigants find the information they need to properly represent themselves in court, an undertaking that can be complicated and confusing.
Sent 13: "Some people can do OK on their own, and some people can do OK with some help," said Linda Rothnagel, the managing attorney for Prairie State Legal Services.
Sent 14: "But other people can't do it.
Sent 15: It's not always easy."Sent 16: Self-representation is a right affirmed by the U.S. Supreme Court.
Sent 17: The practice is far more common in civil matters than in criminal cases.
Sent 18: In fact, self-represented litigants - formally called "pro se" in Latin, or "for oneself" - in criminal defenses are so rare that statistics about the practice generally are not kept, legal experts say.
