Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age.

Question: "What key do index fossils play in dating rock layers?"

Response: "They help to split rocks to layers"

Problem: The earliest signs of people on Jamaica are the remains of the Arawak, an AmerIndian society that originated on the north coast of South America. Arawak peoples migrated to various Caribbean islands, arriving in Jamaica by the beginning of the eighth century. They were peaceful and lived by "slash-and-burn" farming. For meat, they bred pigs and ate iguana, both native to the island. They were highly skilled in such manual activities as thatching and weaving. In fact, the hammock was an AmerIndian invention that remains with us today; it is an object which, more than any other, evokes an image of a warm sunny day on a tropical isle. The Arawak left a legacy of paintings in places such as Runaway Caves near Discovery Bay, and shards of pottery found at their settlements near Nueva Sevilla and Spanish Town have added a little to our knowledge about them. Over 200 Arawak sites have been identified, and it is said that when the Spanish arrived in Jamaica there were approximately 100,000 Arawak living on the island. They called Jamaica "Xaymaca" ("land of wood and water"). Columbus and the Arrival of Europeans Columbus first arrived in Jamaica on 5 May 1494 at Discovery Bay, where there is now a small park in his honor. He stayed for only a few days but returned in 1502, landing here when the ships of his fleet became unserviceable; he waited at St. Ann's Bay for help to arrive from Cuba. After the death of Columbus in 1505, Jamaica became the property of his son Diego, who dispatched Don Juan de Esquivel to the island as Governor. Esquivel arrived in 1510 and created a base called Nueva Sevilla near St. Ann's Bay, from which he hoped to colonize the rest of the island. The Spanish immediately began subjugating the Arawak population, many of whom died under the yoke of oppression and of diseases carried by the Europeans. A number of them committed suicide rather than live the life created for them by the Spanish. The site of Nueva Sevilla proved to be unhealthy and mosquito-ridden, and in 1534 the Spanish founded Villa de la Vega, today known as Spanish Town. Pig breeding was the main occupation of these early settlers, but they also planted sugar cane and other crops that required large numbers of laborers. The number of Arawak had already fallen dramatically, so the Spanish began to import slaves from Africa to work the land; the first Africans arrived in 1517.

Question: "On what island were Arawak pottery shards found?"

Answer: "South America"

Question:
Assisting Zionist causes Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors. Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university. He also submitted various suggestions as to its initial programs. Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development. Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important. Chaim Weizmann later became Israel's first president. Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post. The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons". Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it. After reading the above, is "He was the the biochemist and president of the World Zionist Organization" the correct answer to the question "How did Einstein help establish the University of Jerusalem?"? OPTIONS:
- no
- yes

Answer:
no

Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.
"How does oil reduce friction between moving car parts?" is "By making them stop"?

OPTIONS:
- no
- yes
Output: no

Input: { { lang } } centers on a man who roams the street night after night . Hidden under his hat and rain jacket he strives for one goal : to find the culprit - the one whom he can make responsible for his suffering .
