TASK DEFINITION: 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.
PROBLEM: Paragraph- Sent 1: I stood, and one of her servants took me and Amy to the door.
Sent 2: I looked back to see Nepthys whispering something to her.
Sent 3: He stood to go, but she caught his sleeve and pulled him back for a moment.
Sent 4: I turned back to the door.
Sent 5: "Come on, Amy," I said, "he'll be along soon." Nepthys caught up with us after a minute and walked silently to the end of the hall.
Sent 6: When we got there, another pale servant was waiting for us with a box of dark stained wood.
Sent 7: He offered it to Nepthys, who opened the box: on velvet lining, a wooden hammer and two stakes.
Sent 8: "Mountain ash," said Nepthys.
Sent 9: "That was very kind of her." Closing the box, he paused beside the open door and looked back at me.
Sent 10: "I really hope we find your Rachel," he said.
Sent 11: It looked like he was going to continue, but then he walked out the door.
Sent 12: "I know a quick way to Dvorov's," said Nepthys.
Sent 13: "I bet he's kicking himself now for not having a way to contact me." In a few minutes, we were back to the first door we'd knocked on in this town and Dvorov himself was greeting us.
Sent 14: The pulse from inside made the building sound like a giant heart.
Sent 15: "Yo, my man Nep!
Sent 16: You got the sucker already?" "No, but we got a tip that he might be in your club.
Sent 17: Have you seen him?" "Here, man?
Sent 18: You're crazy.
Sent 19: I haven't had a vampire here since you and - " Nepthys shot a wicked look at him.
Sent 20: "Anyway, long time, man." "That's odd.

SOLUTION: Describe the box?

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.

SOLUTION: What materials let electricity pass easily?

PROBLEM: Paragraph- Sent 1: The size of particles determines how they are carried by flowing water.
Sent 2: Some minerals dissolve in water.
Sent 3: The minerals are then carried along in the solution.
Sent 4: Small particles, such as clay and silt, are carried in suspension.
Sent 5: They are mixed throughout the water.
Sent 6: These particles are not dissolved in the water.
Sent 7: Somewhat bigger particles bounce along the bottom.
Sent 8: Particles, such as sand, move in little jumps near the stream bottom.
Sent 9: They are nudged along by moving water.
Sent 10: The biggest particles move in a different way.
Sent 11: They are too big to hop.
Sent 12: Instead, they roll along the bottom.
Sent 13: Gravel and pebbles move in this way.
Sent 14: These particles roll or drag along the bottom of the water.

SOLUTION:
What are 4 ways that particles are carried in the water?
