Sent 3: "He will be tried in a military and in a civilian court," Essebsi told the television network.
Sent 4: Ben Ali fled to Saudi Arabia earlier this year after a revolt led to his ouster and triggered a wave of protests against longtime rulers across North Africa and the Middle East.
Sent 5: Protests against Ben Ali -- who had ruled Tunisia since 1987 -- began to erupt late last year.

[EX Q]: 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?.
