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: Bin Ladin and his aides did not need a very large sum to finance their planned attack on America.
Sent 2: The 9/11 plotters eventually spent somewhere between $400,000 and $500,000 to plan and conduct their attack.
Sent 3: Consistent with the importance of the project, al Qaeda funded the plotters.
Sent 4: KSM provided his operatives with nearly all the money they needed to travel to the United States, train, and live.
Sent 5: The plotters' tradecraft was not especially sophisticated, but it was good enough.
Sent 6: They moved, stored, and spent their money in ordinary ways, easily defeating the detection mechanisms in place at the time.
Sent 7: The origin of the funds remains unknown, although we have a general idea of how al Qaeda financed itself during the period leading up to 9/11.
Sent 8: General Financing As we explained in chapter 2, Bin Ladin did not fund al Qaeda through a personal fortune and a network of businesses in Sudan.
Sent 9: Instead, al Qaeda relied primarily on a fund-raising network developed over time.
Sent 10: The CIA now estimates that it cost al Qaeda about $30 million per year to sustain its activities before 9/11 and that this money was raised almost entirely through donations.
Sent 11: For many years, the United States thought Bin Ladin financed al Qaeda's expenses through a vast personal inheritance.
Sent 12: Bin Ladin purportedly inherited approximately $300 million when his father died, and was rumored to have had access to these funds to wage jihad while in Sudan and Afghanistan and to secure his leadership position in al Qaeda.
Sent 13: In early 2000, the U.S. government discovered a different reality: roughly from 1970 through 1994, Bin Ladin received about $1 million per year-a significant sum, to be sure, but not a $300 million fortune that could be used to fund jihad.
Sent 14: Then, as part of a Saudi government crackdown early in the 1990s, the Bin Ladin family was forced to find a buyer for Usama's share of the family company in 1994.
Sent 15: The Saudi government subsequently froze the proceeds of the sale.
Sent 16: This action had the effect of divesting Bin Ladin of what otherwise might indeed have been a large fortune.
Sent 17: Nor were Bin Ladin's assets in Sudan a source of money for al Qaeda.
Sent 18: When Bin Ladin lived in Sudan from 1991 to 1996, he owned a number of businesses and other assets.
Question: How did Bin Laden fund the attack against America?.
