TASK DEFINITION: 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 (", ").

PROBLEM: Paragraph- Sent 1: Electric current cannot go through empty space.
Sent 2: Electricity needs something to flow through.
Sent 3: Electricity cannot flow through all materials.
Sent 4: Some materials resist the flow of electricity.
Sent 5: Some materials let electricity pass through easily.
Sent 6: Scientists classify these into two groups.
Sent 7: These groups are called conductors and insulators.
Sent 8: Materials that allow electrons to flow freely are called electric conductors.
Sent 9: Electricity is able to race through these materials.
Sent 10: Copper, aluminum, and steel are good conductors.
Sent 11: Materials that resist the flow of electricity are called electric insulators.
Sent 12: Instead of racing, the current may travel in slow motion, if at all.
Sent 13: Wood, rubber, and plastic are examples of electric insulators.
Sent 14: You probably know that electric wires are made of metal.
Sent 15: They typically have a rubber or plastic coating.
Sent 16: Do you know why?
Sent 17: Metals are good electric conductors.
Sent 18: They offer little resistance to electricity.
Question: What are some examples of materials that resist or prevent the flow of electrical current through them?.

SOLUTION: 11, 13.

PROBLEM: Paragraph- Sent 1: Born on May 11, 1975, in Mazraa, Lebanon, Ziad Jarrah came from an affluent family and attended private, Christian schools.
Sent 2: Like Atta, Binalshibh, and Shehhi, Jarrah aspired to pursue higher education in Germany.
Sent 3: In April 1996, he and a cousin enrolled at a junior college in Greifswald, in northeastern Germany.
Sent 4: There Jarrah met and became intimate with Aysel Senguen, the daughter of Turkish immigrants, who was preparing to study dentistry.
Sent 5: Even with the benefit of hindsight, Jarrah hardly seems a likely candidate for becoming an Islamic extremist.
Sent 6: Far from displaying radical beliefs when he first moved to Germany, he arrived with a reputation for knowing where to find the best discos and beaches in Beirut, and in Greifswald was known to enjoy student parties and drinking beer.
Sent 7: Although he continued to share an apartment in Greifswald with his cousin, Jarrah was mostly at Senguen's apartment.
Sent 8: Witnesses interviewed by German authorities after 9/11, however, recall that Jarrah started showing signs of radicalization as early as the end of 1996.
Sent 9: After returning from a trip home to Lebanon, Jarrah started living more strictly according to the Koran.
Sent 10: He read brochures in Arabic about jihad, held forth to friends on the subject of holy war, and professed disaffection with his previous life and a desire not to leave the world "in a natural way."Sent 11: In September 1997, Jarrah abruptly switched his intended course of study from dentistry to aircraft engineering-at the Technical University of Hamburg-Harburg.
Sent 12: His motivation for this decision remains unclear.
Sent 13: The rationale he expressed to Senguen-that he had been interested in aviation since playing with toy airplanes as a child-rings somewhat hollow.
Sent 14: In any event, Jarrah appears already to have had Hamburg contacts by this time, some of whom may have played a role in steering him toward Islamic extremism.
Sent 15: Following his move to Hamburg that fall, he began visiting Senguen in Greifswald on weekends, until she moved to the German city of Bochum one year later to enroll in dental school.
Sent 16: Around the same time, he began speaking increasingly about religion, and his visits to Senguen became less and less frequent.
Sent 17: He began criticizing her for not being religious enough and for dressing too provocatively.
Sent 18: He grew a full beard and started praying regularly.
Question: WHAT YEAR WAS ZIAD JARRAH BORN?.
