The side of Malaquez's parcel gave way to reveal a greenmunk caught in a sheen of solid air. Bits of leaf mold flew from under his feet as he ran to greet a friend or a bringer of food. Tasha oohed in awe. I said, "Frodo's been visiting you, eh?" Malaquez said, "Your pet?" "Hardly. He lives around here somewhere. I suppose he was attracted to the commotion up the hill." "Ah," Malaquez said. "Why 'Frodo'?" Tasha said, "A little fellow with big, furry feet. What else could he be called?" She handed the sculpture to me. I almost dropped it; I expected it to weigh no more than a holo. "Heavy," I said, as if he might not have known. He laughed. "My last piece was of four old Undersiders crouched around a trash fire. Be glad someone didn't toss that to you." He spoke of his art with the enthusiasm of a seven-year-old. "Um, I should wait to importune you, but..."

Question: "Where does Frodo live?"

Response: "Within the narrator's range"

A: yes

Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Question: "The force that holds our moon in place, is an example of what type of force?"

Response: "kinetic force"

A: no

It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place.

Question: "What are the earth's two poles?"

Response: "north and south"

A:
no
