Example Input: 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 Ailies 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 conglomeratesa dozen family-run combines, each involved in mining, manufacturing, marketing, shipping, and banking.

Sent 18: The result was the attack on the American fleet at Pearl Harbor (7 December 1941) and total war.
Question: Why did japan occupy Manchuria in 1931?.

Example Input: Paragraph- Sent 1: As noted above, the 9/11 plotters spent somewhere between $400,000 and $500,000 to plan and conduct their attack.
Sent 2: The available evidence indicates that the 19 operatives were funded by al Qaeda, either through wire transfers or cash provided by KSM, which they carried into the United States or deposited in foreign accounts and accessed from this country.
Sent 3: Our investigation has uncovered no credible evidence that any person in the United States gave the hijackers substantial financial assistance.
Sent 4: Similarly, we have seen no evidence that any foreign government-or foreign government official-supplied any funding.
Sent 5: We have found no evidence that the Hamburg cell members (Atta, Shehhi, Jarrah, and Binalshibh) received funds from al Qaeda before late 1999.
Sent 6: It appears they supported themselves.
Sent 7: KSM, Binalshibh, and another plot facilitator, Mustafa al Hawsawi, each received money, in some cases perhaps as much as $10,000, to perform their roles in the plot.
Sent 8: After the Hamburg recruits joined the 9/11 conspiracy, al Qaeda began giving them money.
Sent 9: Our knowledge of the funding during this period, before the operatives entered the United States, remains murky.
Sent 10: According to KSM, the Hamburg cell members each received $5,000 to pay for their return to Germany from Afghanistan after they had been selected to join the plot, and they received additional funds for travel from Germany to the United States.
Sent 11: Financial transactions of the plotters are discussed in more detail in chapter 7.
Sent 12: Requirements for a Successful Attack As some of the core operatives prepared to leave for the United States, al Qaeda's leaders could have reflected on what they needed to be able to do in order to organize and conduct a complex international terrorist operation to inflict catastrophic harm.
Sent 13: We believe such a list of requirements would have included leaders able to evaluate, approve, and supervise the planning and direction of the operation; communications sufficient to enable planning and direction of the operatives and those who would be helping them; a personnel system that could recruit candidates, vet them, indoctrinate them, and give them necessary training; an intelligence effort to gather required information and form assessments of enemy strengths and weaknesses; the ability to move people; and the ability to raise and move the necessary money.
Sent 14: The information we have presented about the development of the planes operation shows how, by the spring and summer of 2000, al Qaeda was able to meet these requirements.
Sent 15: By late May 2000, two operatives assigned to the planes operation were already in the United States.
Sent 16: Three of the four Hamburg cell members would soon arrive.

Sent 4: Since the 1960s, we have sent many spacecraft into space.
Sent 5: Some are still traveling away from Earth.
Sent 6: So it is possible to overcome gravity.
Sent 7: Do you need a giant rocket to overcome gravity?
Sent 8: No, you actually overcome gravity every day.
Sent 9: Think about when you climb a set of stairs.
Sent 10: When you do, you are overcoming gravity.
Sent 11: What if you jump on a trampoline?
Sent 12: You are overcoming gravity for a few seconds.
Sent 13: Everyone can overcome gravity.
Sent 14: You just need to apply a force larger than gravity.
Sent 15: Think about that the next time you jump into the air.
Sent 16: You are overcoming gravity for a brief second.
Sent 17: Enjoy it while it lasts.
Sent 18: Eventually, gravity will win the battle.
Question: Are you overcoming gravity for an hour when you jump on a trampoline?.
Example Output:
You are only temporarily overcoming gravity.
