Magnetism is the ability of a material to be attracted by a magnet. It also include the ability for some material to act like a magnet. No doubt youve handled refrigerator magnets. You can see some in Figure 1.28. You probably know they stick to a metal refrigerator. This is what holds your homework up. Maybe your little sisters drawings are hung on the fridge in this manner. Do magnets stick to all materials? Of course not. You have probably checked and they do not stick to other surfaces. They do not stick to wooden doors or glass windows. Wood and glass are not attracted to a magnet. Obviously, only certain materials are attracted to magnets.

Question: "What ability of material can also act like a magnet?"

Response: "The ability for some material to act like a magnet"

A: yes

In remarks during a ribbon-cutting ceremony here on Wednesday, Gov. George E. Pataki said he expected the facility to generate thousands more jobs in the Hudson Valley area for contractors and suppliers catering to the factory. He praised IBM for being "a critical partner in our economic development efforts" in New York state. In a brief speech, Samuel J. Palmisano, IBM's chief executive, emphasized that it was important to make long-term investments despite the current slump in the technology business. "To play to win in technology, you innovate and you lead," he said. But manufacturing technology products is a costly and cyclical business. In June, IBM announced that it was taking a charge of more than $2 billion against earnings. The largest single reasons for the charge were the cost of getting out of the business of manufacturing hard disks for storage, which it sold to Hitachi, and closing down some of its older semiconductor operations. But Kelly said the demand for advanced chips, like those produced at IBM's facility in Burlington, Vt., is strong. "I need more capacity in that end of the market," he said, "and this is factory is critical to meeting that growing demand." If IBM has miscalculated the demand, it will suffer badly as both the high operating costs and depreciation on the huge capital investment for the East Fishkill factory drag down earnings. But industry analysts said the plant should be insulated from a falloff in one or a few segments of the semiconductor market.

Question: "Who asked for more capacity in that end of the market?"

Response: "Samuel J. Palmisano"

A: no

Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate.

Question: "What are clues that the highest mountain on earth was once covered by sea?"

Response: "Earth was completely covered by the sea at one time"

A:
no
