instruction:
You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.
question:
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.
answer:
What cell operatives arrived in the US shortly after May 2000?

question:
Paragraph- Sent 1: (CNN) -- German art collector Cornelius Gurlitt, whose nearly priceless collection was confiscated because it was suspected to contain pieces looted by the Nazis, died Tuesday and left the masterpieces to a Swiss museum.
Sent 2: One day after Gurlitt's death at the age of 81, the Museum of Fine Arts Bern announced that Gurlitt had named it "his unrestricted and unfettered sole heir."Sent 3: The news came as a surprise, the museum said Wednesday, because Gurlitt had never had any connection to it.
Sent 4: The museum's directors are delighted at the news, they said in a statement, but also recognize that there are outstanding legal and ethical questions surrounding the collection.
Sent 5: Gurlitt had undergone major heart surgery and was hospitalized for many weeks, his representative said in a statement.
Sent 6: Gurlitt grabbed the attention of the art world when German prosecutors seized more than 1,200 paintings from his Munich apartment in 2012, including works by Picasso and Matisse.
Sent 7: The collection was confiscated as part of an investigation into tax fraud, but then it was thought that some of the paintings may have been works that were looted by the Nazis.
Sent 8: Just last month, part of the collection was returned to Gurlitt as part of a deal with Germany's cultural authorities and the Bavarian Justice Ministry.
Sent 9: Under the agreement, works owned by Gurlitt that were not under suspicion were returned to him.
Sent 10: Those suspected of being stolen were to be held securely while a task force investigates their provenance -- and will be returned to their original Jewish owners or their descendants if a claim is proven.
Sent 11: Gurlitt's representative said that with the art collector's death, the investigation into the collection ceases.
Sent 12: The court that was handling the investigation proceedings will now function as an estate court in the case.
answer:
Which Swiss museum had Cornelius Gurlitt named his sole heir?
