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.

Mr. Thorndike had risen, and, in farewell, was holding out his hand to Andrews. He turned, and across the court-room the eyes of the financier and the stenographer met. At the sight of the great man, Spear flushed crimson, and then his look of despair slowly disappeared; and into his eyes there came incredulously hope and gratitude. He turned his head suddenly to the wall. Mr. Thorndike stood irresolute, and then sank back into his chair. The first man in the line was already at the railing, and the questions put to him by the judge were being repeated to him by the other assistant district attorney and a court attendant. His muttered answers were in turn repeated to the judge. "Says he's married, naturalized citizen, Lutheran Church, die- cutter by profession." The probation officer, her hands filled with papers, bustled forward and whispered. "Mrs. Austin says," continued the district attorney, "she's looked into this case, and asks to have the man turned over to her. He has a wife and three children; has supported them for five years." "Is the wife in court?" the judge said. A thin, washed-out, pretty woman stood up, and clasped her hands in front of her. "Has this man been a good husband to you, madam?" asked the young judge. The woman broke into vehement assurances. No man could have been a better husband. Would she take him back? Indeed she would take him back. She held out her hands as though she would physically drag her husband from the pillory. The judge bowed toward the probation officer, and she beckoned the prisoner to her.

Question: "Who spoke up on behalf of the wife?"

Response: "Judge"

Tropical climates are found around the equator. These climates have warm temperatures year round. Tropical climates may be very wet or wet and dry. Tropical wet climates occur at or very near the equator. They have high rainfall year round. Tropical rainforests grow in this type of climate. Tropical wet and dry climates also occur near the equator. They receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season. The main plants are grasses. Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier.
