Problem: 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: "Can you stick your sister's drawings to a wooden cupboard with a magnet?"

Answer: "No, magnets do not stick to wood"

OPTIONS:
- no

Problem: Over the centuries, the living here has always been easy enough to attract a steady stream of immigrants. Bountiful food sources might have made Malaysia an inviting place for the contemporaries of Java Manin 230,000 b.c. But thus far, the country's earliest traces of homo sapiens, found in the Niah Caves of northern Sarawak, are fragments of a skull dating to 40,000 b.c. On the peninsula, the oldest human-related relics (10,000 b.c. ) are Stone Age tools of the Negritos. These small, dark Melanesians are related in type to Australian aborigines and are confined today to the forests of the northern highlands. By 2,000 b.c. , these timid, gentle nomads hunting with bow and arrow were driven back from the coasts by waves of sturdy immigrants arriving in outrigger canoes equipped with sails. Mongolians from South China and Polynesian and Malay peoples from the Philippines and the Indonesian islands settled along the rivers of the peninsula and northern Borneo. They practiced a slash-and-burn agriculture of yams and millet, a technique that exhausted the soil and imposed a semi-nomadic existence from one jungle clearing to another. Families lived in wooden longhouses like those still to be seen today among the Iban peoples of Sarawak. Another unit was added on to the communal dwelling each time a marriage created a new family. Other tough migrants from the South Seas settled along the coastssailors, fishermen, traders (for the most part pirates)known euphemistically as orang laut (sea people).

Question: "What were the oldest human-related relics found on the peninsula?"

Problem: Here the omnibus came up, and I rode back to Manchester. The whole conversation took up very little more time than it will take to read it; but I thought it worth recording, as characteristic of the people now suffering in Lancashire from no fault of their own. I know the people well. The greatest number of them would starve themselves to that degree that they would not be of much more physical use in this world, before they would condescend to beg. But starving to death is hard work. What will winter bring to them when severe weather begins to tell upon constitutions lowered in tone by a starvation diet--a diet so different to what they have been used to when in work? What will the 1s. 6d. a-head weekly do for them in that hard time? If something more than this is not done for them, when more food, clothing, and fire are necessary to everybody, calamities may arise which will cost England a hundred times more than a sufficient relief--a relief worthy of those who are suffering, and of the nation they belong to--would have cost. In the meantime the cold wings of winter already begin to overshadow the land; and every day lost involves the lives, or the future usefulness, of thousands of our best population.

Question: "What country is Lancashire in?"

Answer: "Ireland"
