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: Hundreds of thousands of years before China was to become the world's longest-running civilization, the prologue was enacted by means of the flicker of a carefully tended fire.
Sent 2: Peking Man, a forebear of Homo sapiens, achieved a mastery of fire.
Sent 3: We might call it the first Chinese invention.
Sent 4: Not that he devised flint and steel, matches, or any other way of creating fire.
Sent 5: Peking Man simply learned how to capture flame, perhaps from a forest fire, and keep it alight.
Sent 6: He thus enjoyed two revolutionary luxuries: light and heat.
Sent 7: Technologically and sociologically, it was a phenomenal breakthrough: with fire, communities could live year 'round in one cave, in which cooking and even smelting could be pursued.
Sent 8: And so, by 600,000 b.c., about 50 km (31 miles) southwest of present-day Beijing, the ancestors of mankind were ready to settle down.
Sent 9: Several hundred thousand years later, when Marco Polo reached the capital of China, he was astonished by a further development in fire technology.
Sent 10: The Chinese, he announced, used black stones dug out of mountains as fuel.
Sent 11: Europeans did not yet have a word for "coal," nor had they discovered a use for it.
Sent 12: The First Dynasty The confluence of mythology and history in China took place around 4,000 years ago during what is referred to as the Xia (Hsia) Dynasty.
Sent 13: This was still the Stone Age, but the people are thought to have made silk from thread produced by the worms they cultivated on the leaves of their mulberry trees.
Sent 14: And written language (which evolved as early as 4,500 to 5,000 years ago) was already in use, originally by oracles and then by official scribesChina's first scholars.
Sent 15: During the second of the quasi-legendary dynasties, the Shang (from about the 16th to 11th centuries b.c.), the Chinese developed an interest in art.
Sent 16: Careful geometric designs as well as dragon and bird motifs adorned bowls and implements.
Sent 17: And with the arrival of the Bronze Age, the Chinese created bronze vessels of such beauty and originality that, until modern times, archaeologists refused to believe they were cast 3,000 years ago.
Sent 18: The Shang Dynasty gave rise to the concept of one Chinese nation under one government.

Q: Paragraph- Sent 1: For more than half a century, the Passaic County Legal Aid Society has fought on behalf of the county's poor, in disputes ranging from housing to child custody to public assistance.
Sent 2: But for the last several years it has often done that job poorly, according to state and federal officials.
Sent 3: And barring a long-shot legal victory, as of Jan. 1 the autonomous county office will be replaced by a new agency whose administrators will report to a director based in Jersey City.
Sent 4: Federal legal aid officials drew up the new service area uniting Bergen, Hudson, and Passaic counties in June, insisting the change will trim administrative costs without compromising services.
Sent 5: The Passaic County office and its supporters see it differently.
Sent 6: They say top decision-makers will be too far from the individuals and non-profit agencies that rely on the office for help.
Sent 7: And in a federal lawsuit, the agency's leadership argues that a merger would jeopardize its educational programs and minority hiring efforts, and that its imposition amounts to bureaucratic bullying by state and federal officials.
Sent 8: Those same officials have repeatedly accused the Passaic County office of mismanagement.
Sent 9: Reviews since 1995 have found evidence of shoddy accounting, poor morale, excessive staff turnover, and double counting of cases - and alleged that the office made limited efforts to rectify the problems.
Sent 10: At times in recent years, the office has received its state and federal funding on a month-to-month basis, which one federal official called "one step short of defunding."Sent 11: Leaders of the county agency, which employs 14 attorneys, five paralegals, and nine support staff at offices in Paterson and Wanaque, say officials have "greatly exaggerated" the office's problems, which they call mostly bureaucratic.
Sent 12: "Just let them argue that their [merger] plan makes sense," Maxim Thorne, the office's deputy director, said of the higher-level legal aid officials.
Sent 13: "They could never replicate our services or equal the accumulated value of this office."Sent 14: Over the summer, the office reapplied for a federal grant to serve Passaic County in the coming year.
Sent 15: But Legal Services Corp. in Washington rejected the application, saying it failed to address the service needs of the entire tri-county area - a requirement under the new rules.
Sent 16: By mid-December, the federal body is expected to award Passaic County's federal funding - about $385,000 this year - to Northeast New Jersey Legal Services, the tri-county agency.
Sent 17: State funds of about $1.6 million could follow, although Thorne noted the state appropriated $927,000 of that amount through June 2003.
Sent 18: The state Treasury Department's legal services representative did not return repeated calls for comment.
Question: Why is there need for an alternative to the Passaic County Legal Aid Society?.

A: 2, 4, 9, 15.

Q: Paragraph- Sent 1: Soon Sweetwater realised that his work was over for the night and planned to leave.
Sent 2: But there was one point to be settled first.
Sent 3: Was there any other means of exit from these grounds save that offered by the ordinary driveway?
Sent 4: He had an impression that in one of his strolls about, he had detected the outlines of a door in what looked like a high brick wall in the extreme rear.
Sent 5: If so, it were well worth his while to know where that door led.
Sent 6: Working his way along in the shadow cast by the house and afterward by the stable itself, he came upon what was certainly a wall and a wall with a door in it.
Sent 7: He could see the latter plainly from where he halted in the thick of the shadows.
Sent 8: The moonlight shone broadly on it, and he could detect the very shape and size of its lock.
Sent 9: It might be as well to try that lock, but he would have to cross a very wide strip of moonlight in order to do so, and he feared to attract attention to his extreme inquisitiveness.
Sent 10: Yet who was there to notice him at this hour?
Sent 11: Mr. Cumberland had not moved, the girls were upstairs, Zadok was busy with his paper, and the footman dozing over his pipe in his room over the stable.
Sent 12: Sweetwater had just come from that room, and he knew.
Question: Who could have possibly noticed Sweetwater if the timing was less ideal?.

A:
10, 11, 12.
