user: instruction:
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 (", ").

Paragraph- Sent 1: Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States.
Sent 2: Millions of men and women readied themselves for work.
Sent 3: Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City.
Sent 4: Others went to Arlington, Virginia, to the Pentagon.
Sent 5: Across the Potomac River, the United States Congress was back in session.
Sent 6: At the other end of Pennsylvania Avenue, people began to line up for a White House tour.

Sent 11: Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport.
Sent 12: When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures.
Sent 13: Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft.
Sent 14: This did not hinder Atta's plans.
Sent 15: Atta and Omari arrived in Boston at 6:45.
Sent 16: Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport.

Sent 18: It would be their final conversation. 
Question: Who was Atta's final conversation with ?.

question:
Paragraph- Sent 1: Triumph and Disaster: The 20th century saw a stupendous release of energies that had been pent up for the 250 years of Tokugawa isolation.
Sent 2: By 1930 raw-material production had tripled the figure of 1900, manufactured goods had increased twelve-fold, and heavy industry was galloping towards maturity.
Sent 3: Britain led the World War I allies in large orders for munitions, while Japan expanded sales of manufactured goods to Asian and other markets cut off from their usual European suppliers.
Sent 4: Merchant shipping doubled in size and increased its income ten-fold as the European fleets were destroyed.
Sent 5: Setbacks in the 1930s caused by the European postwar slump were only a spur to redouble efforts by diversifying heavy industry into the machine-making, metallurgical, and chemical sectors.
Sent 6: Even the terrible 1923 Tokyo earthquake, which cost over 100,000 lives and billions of dollars, provided another stimulus due to the construction boom that followed.
Sent 7: Riding the crest of this economic upsurge were the zaibatsu conglomerates — a dozen family-run combines, each involved in mining, manufacturing, marketing, shipping, and banking.
Sent 8: These tightly controlled commercial pyramids were the true heirs to the old feudal structures.
Sent 9: Japan’s progress toward parliamentary democracy was halted in the 1930s by the growing nationalism being imposed on government by the generals and admirals.
Sent 10: They proclaimed Japan’s mission to bring progress to its backward Asian neighbors in language not so very different from that of the Europeans in Africa or the US in Latin America.
Sent 11: After the Russian Revolution of 1917, the Soviet Union was regarded as a major threat to Japan’s security, and the army felt it needed Manchuria and whatever other Chinese territory it could control as a buffer against Russian advances.
Sent 12: In 1931 the Japanese occupied Manchuria.
Sent 13: And then in 1937, with the popular support of ultra-right-wing groups, the army overrode parliamentary resistance in Tokyo and went to war against the Chinese Nationalists.
Sent 14: By 1938, they held Nanking, Hankow, and Canton.
Sent 15: Japanese expansionist policies were leading to direct confrontation with the West.
Sent 16: Japan hoped that war in Europe would divert the Soviet Union from interference in East Asia, giving Japan a free hand both in China and, through its alliance with Germany, in French Indochina after the defeat of France.
Sent 17: The US responded to the Japanese invasion of Indochina with a trade and fuel embargo, cutting off 90 percent of Japan’s supplies.
Sent 18: The result was the attack on the American fleet at Pearl Harbor (7 December 1941) and total war. 
Question: What act against Japan resulted in the attack on Pearl Harbor?.
answer:
17.


question:
Paragraph- Sent 1: Einstein was displeased with quantum theory and mechanics (the very theory he helped create), despite its acceptance by other physicists, stating that God "is not playing at dice."Sent 2: Einstein continued to maintain his disbelief in the theory, and attempted unsuccessfully to disprove it until he died at the age of 76.
Sent 3: In 1917, at the height of his work on relativity, Einstein published an article in Physikalische Zeitschrift that proposed the possibility of stimulated emission, the physical process that makes possible the maser and the laser.
Sent 4: This article showed that the statistics of absorption and emission of light would only be consistent with Planck's distribution law if the emission of light into a mode with n photons would be enhanced statistically compared to the emission of light into an empty mode.
Sent 5: This paper was enormously influential in the later development of quantum mechanics, because it was the first paper to show that the statistics of atomic transitions had simple laws.
Sent 6: Einstein discovered Louis de Broglie's work, and supported his ideas, which were received skeptically at first.
Sent 7: In another major paper from this era, Einstein gave a wave equation for de Broglie waves, which Einstein suggested was the Hamilton-Jacobi equation of mechanics.
Sent 8: This paper would inspire Schrodinger's work of 1926. 
Question: What year did Einstein publish an article regarding the statistics of absorption and Planck's distribution law?.
answer:


assistant: 2.
