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.

[Q]: Paragraph- Sent 1: Rivers flowing over gentle slopes move more slowly.
Sent 2: They move much more slowly than a mountain stream.
Sent 3: These slow moving streams create different types of features than mountain streams.
Sent 4: Slow moving water erodes the sides of their channels more than the bottom.
Sent 5: Also, large curves in the stream form.
Sent 6: These curves are called meanders.
Sent 7: Meanders are caused by erosion and deposition.
Sent 8: Remember, faster moving water causes erosion more quickly.
Sent 9: Slower moving water erodes material more slowly.
Sent 10: If water is moving slowly enough, the sediment being carried may settle out.
Sent 11: This settling out, or dropping off, of sediment is deposition.
Sent 12: The curves are called meanders because they slowly wander over the land.
Sent 13: As meanders erode from side to side, they create a floodplain.
Sent 14: This is a broad, flat area on both sides of a river.
Sent 15: Eventually, a meander may become cut off from the rest of the river.
Sent 16: This forms an oxbow lake.
[A]: Can a mountain stream create a meander?

[Q]: Paragraph- Sent 1: Feel the top of your desk.
Sent 2: Does it look and feel smooth?
Sent 3: Yes, it feels and looks smooth, but is it really?
Sent 4: Even when surfaces look smooth to the unaided eye, they may not be.
Sent 5: Scientists use a microscope to look at things more closely.
Sent 6: Through a microscope, smooth surfaces may appear rough or bumpy.
Sent 7: Look at the metal surfaces in Figure 1.8.
Sent 8: The metal foil is so smooth that it is shiny.
Sent 9: However, when highly magnified, it is clearly not smooth.
Sent 10: It actually looks to be very bumpy.
Sent 11: All those bumps grab the bumps of other surfaces.
Sent 12: They grind together.
Sent 13: They oppose the motion of the two surfaces.
Sent 14: Now you know what causes friction.
[A]: What does shiny metal foil look like when it is highly magnified?

[Q]: Paragraph- Sent 1: Pester came running into the room.
Sent 2: He came to a fast stop when he saw the dog.
Sent 3: He'd seen a dog before, every cat has, and he used to live with a black dog named Henry, but he'd never seen a brown one before.
Sent 4: It seemed strange to him, but not as strange as it was to see Linda the brown chicken in the living room last spring.
Sent 5: That still confused him.
Sent 6: He thought he liked this dog, not because of the color, but because it was small.
Sent 7: And it was so hairy.
Sent 8: It was a like a mop that could run around.
Sent 9: He jumped on his favorite chair and looked down as Maggie ran under it.
Sent 10: She was kind of cute for a dog, Pester thought to himself.
Sent 11: He layed down on the chair and pawed at her as she ran in a circle under it.
Sent 12: He tapped her ears as she went by, and waved his tail like a flag trying to get her attention.
Sent 13: After a little more of this, Pester curled up in a ball on the chair and took a nap.
[A]:
Where was Pester when he played with Maggie?
