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: For the past few weeks my usual stack of junk mail has been supplemented with a steady stream of 2001 tax statements and forms, reminding me that the clock has begun ticking towards April 15.
Sent 2: I admit that even though my taxes are relatively simple and I took a tax course in law school, I still hire an accountant to complete the forms.
Sent 3: I found law school discussions concerning the concept of "basis" or "stepped-up basis" to be about as easy to follow as the rule against perpetuities.
Sent 4: Of course, the one tax concept that we all understand is an audit.
Sent 5: The prospect of being audited may be one of life's most stressful experiences, so I can only imagine how daunting it would be if I had to do so without any professional assistance.
Sent 6: But that is the exact situation that many low- and moderate-income taxpayers face when being audited by the Internal Revenue Service.
Sent 7: With the push in recent years to move people from welfare to work, there are many new low-wage first-time filers, who are often automatically audited.
Sent 8: Still others fail to file, file incorrectly or fail to take advantage of programs like the Earned Income Tax Credit.
Sent 9: Legal Clinics: In an effort to redress this problem, the IRS has taken the unusual step of funding legal clinics that assist low-income taxpayers.
Sent 10: Under the project, which was created as part of the IRS Restructuring and Reform Act of 1998, the IRS provides funding to programs that offer tax education and representation to low-income individuals.
Sent 11: This may seem a little bit like supplying a rival army with ammunition, but in fact it is entirely consistent with the stated mission of the IRS.
Sent 12: In a press release referring to the program, IRS Commissioner Charles O. Rossotti stated that the clinics mesh with the IRS mission statement of providing "America's taxpayers top quality service by helping them understand and meet their tax responsibilities by applying the tax law with integrity and fairness to all."Sent 13: He went on to say that "these clinics fill a critical need.
Sent 14: They reach out to help people who frequently have nowhere else to turn for legal assistance on tax matters."Sent 15: A number of programs in New York that are funded by the IRS rely heavily on volunteer lawyers to serve clients, including The Brooklyn Low-Income Taxpayer Clinic of South Brooklyn Legal Services and the Low Income Taxpayer Clinic operated by The Legal Aid Society's Volunteer Division.
Sent 16: These programs address a valid complaint by corporate tax lawyers that there are not enough opportunities for them to use their unique skills to help individuals on a pro bono basis.
Sent 17: However, participation in a taxpayer clinic is not solely limited to tax experts since these programs provide extensive training and mentoring.
Sent 18: One of the most important services provided to clients of taxpayer clinics is assistance in seeking a refund under the Earned Income Tax Credit provisions.
Question: Many low- and moderate-income taxpayers face what situation when being audited by the Internal Revenue Service?.

Input: Consider Input: Paragraph- Sent 1: Although Bin Ladin, Atef, and KSM initially contemplated using established al Qaeda members to execute the planes operation, the late 1999 arrival in Kandahar of four aspiring jihadists from Germany suddenly presented a more attractive alternative.
Sent 2: The Hamburg group shared the anti-U.S. fervor of the other candidates for the operation, but added the enormous advantages of fluency in English and familiarity with life in the West, based on years that each member of the group had spent living in Germany.
Sent 3: Not surprisingly, Mohamed Atta, Ramzi Binalshibh, Marwan al Shehhi, and Ziad Jarrah would all become key players in the 9/11 conspiracy.
Sent 4: Mohamed Atta was born on September 1, 1968, in Kafr el Sheikh, Egypt, to a middle-class family headed by his father, an attorney.
Sent 5: After graduating from Cairo University with a degree in architectural engineering in 1990, Atta worked as an urban planner in Cairo for a couple of years.
Sent 6: In the fall of 1991, he asked a German family he had met in Cairo to help him continue his education in Germany.
Sent 7: They suggested he come to Hamburg and invited him to live with them there, at least initially.
Sent 8: After completing a course in German, Atta traveled to Germany for the first time in July 1992.
Sent 9: He resided briefly in Stuttgart and then, in the fall of 1992, moved to Hamburg to live with his host family.
Sent 10: After enrolling at the University of Hamburg, he promptly transferred into the city engineering and planning course at the Technical University of Hamburg-Harburg, where he would remain registered as a student until the fall of 1999.
Sent 11: He appears to have applied himself fairly seriously to his studies (at least in comparison to his jihadist friends) and actually received his degree shortly before traveling to Afghanistan.
Sent 12: In school, Atta came across as very intelligent and reasonably pleasant, with an excellent command of the German language.
Sent 13: When Atta arrived in Germany, he appeared religious, but not fanatically so.
Sent 14: This would change, especially as his tendency to assert leadership became increasingly pronounced.
Sent 15: According to Binalshibh, as early as 1995 Atta sought to organize a Muslim student association in Hamburg.
Sent 16: In the fall of 1997, he joined a working group at the Quds mosque in Hamburg, a group designed to bridge the gap between Muslims and Christians.
Sent 17: Atta proved a poor bridge, however, because of his abrasive and increasingly dogmatic personality.
Sent 18: But among those who shared his beliefs, Atta stood out as a decisionmaker.
Question: how many years after graduating Cairo university passed before Mohamed Atta traveled to Germany.
Output: 5, 8.
