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: Our sun and other stars release light energy.
Sent 2: At least this is what we see.
Sent 3: Our Sun and stars also emit more than just light.
Sent 4: Scientists call the type of energy that our Sun and stars release electromagnetic energy.
Sent 5: This form of energy travels through space.
Sent 6: Electromagnetic energy includes the light we see.
Sent 7: It also includes much more.
Sent 8: Many of these things we know about, but dont always think about.
Sent 9: Electromagnetic energy includes radio waves, microwaves, and X rays.
Sent 10: We now have devices in our homes and offices that release these same forms of energy.
Sent 11: We use electromagnetic energy to make our lives better.

Answer: Why do we use radio waves, microwaves, and X rays?

Question: Paragraph- Sent 1: After the 1998 embassy bombings, the U.S. government tried to develop a clearer picture of Bin Ladin's finances.
Sent 2: A U.S. interagency group traveled to Saudi Arabia twice, in 1999 and 2000, to get information from the Saudis about their understanding of those finances.
Sent 3: The group eventually concluded that the oft-repeated assertion that Bin Ladin was funding al Qaeda from his personal fortune was in fact not true.
Sent 4: The officials developed a new theory: al Qaeda was getting its money elsewhere, and the United States needed to focus on other sources of funding, such as charities, wealthy donors, and financial facilitators.
Sent 5: Ultimately, although the intelligence community devoted more resources to the issue and produced somewhat more intelligence, it remained difficult to distinguish al Qaeda's financial transactions among the vast sums moving in the international financial system.
Sent 6: The CIA was not able to find or disrupt al Qaeda's money flows.
Sent 7: The NSC staff thought that one possible solution to these weaknesses in the intelligence community was to create an all-source terrorist-financing intelligence analysis center.
Sent 8: Clarke pushed for the funding of such a center at Treasury, but neither Treasury nor the CIA was willing to commit the resources.
Sent 9: Within the United States, various FBI field offices gathered intelligence on organizations suspected of raising funds for al Qaeda or other terrorist groups.
Sent 10: By 9/11, FBI agents understood that there were extremist organizations operating within the United States supporting a global jihadist movement and with substantial connections to al Qaeda.
Sent 11: The FBI operated a web of informants, conducted electronic surveillance, and had opened significant investigations in a number of field offices, including New York, Chicago, Detroit, San Diego, and Minneapolis.
Sent 12: On a national level, however, the FBI never used the information to gain a systematic or strategic understanding of the nature and extent of al Qaeda fundraising.
Sent 13: Treasury regulators, as well as U.S. financial institutions, were generally focused on finding and deterring or disrupting the vast flows of U.S. currency generated by drug trafficking and high-level international fraud.
Sent 14: Large-scale scandals, such as the use of the Bank of New York by Russian money launderers to move millions of dollars out of Russia, captured the attention of the Department of the Treasury and of Congress.
Sent 15: Before 9/11, Treasury did not consider terrorist financing important enough to mention in its national strategy for money laundering.

Answer: WHERE DID THE FBI CONDUCT ELECTRONIC SURVEILLANCE?

Question: Paragraph- Sent 1: You know that friction also causes heat.
Sent 2: Think about when you rub your hands together.
Sent 3: It is friction that makes them warm.
Sent 4: But why does this happen?
Sent 5: Friction causes the molecules on rubbing surfaces to move faster.
Sent 6: Faster moving particles have more heat energy.
Sent 7: Heat from friction can be useful.
Sent 8: Can you think of other places where you might find friction?
Sent 9: Friction also lets you light a match (see Figure 1.10).
Sent 10: Heat from friction can also cause problems.
Sent 11: It can cause a car to overheat.
Sent 12: To reduce friction, oil is added to the engine.
Sent 13: Oil coats the surfaces of moving parts.
Sent 14: This coating of oil makes them slippery.
Sent 15: When things are slippery there is less friction.
Sent 16: Have you ever seen a sign that says, slippery when wet?
Sent 17: This too has to do with friction.
Sent 18: Water, like oil, can reduce friction.
Sent 19: The wet surface may allow your shoes to slide more easily.

Answer:
Why do your hands become warmer when you rub them together?
