Input: 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.
"How are index fossils used?" is "They are collectable items"?

OPTIONS:
- no

Input: Moscow (CNN) -- Divers have completed their search of a Russian cruise ship that sank last weekend with the loss of many lives, the Emergency Situations Ministry told CNN Friday. The official death toll has reached 114 -- including 66 women, 28 children and 20 men, the ministry said. The bodies of 15 people are still missing. There were 208 people on the "Bulgaria" at the time of the accident Sunday, of whom 79 were rescued. Divers have checked all the boat's compartments, the ministry said, and are now looking for more bodies around the boat as well downstream on the Volga River, where they could have been carried by the current. The area where search efforts continue has been enlarged to 200 kilometers (125 miles) from the scene, Russian Transport Minister Igor Levitin said at a briefing Friday. Preparations are under way for the cruise ship to be raised from the river bottom in the coming days. Two large boat cranes, one from Moscow and another one from Volgograd, which will be used for the lifting, are on the way to the accident site. "We have asked the Emergency Situations Ministry to keep 23 divers at the scene to continue the search for bodies even during the lifting operation," Levitin said. Specialist military divers were brought in mid-week to aid in the search efforts. Four people face criminal charges over the sinking of the ship, which Russian media have called the most devastating river accident in the country's history.

Does the response "23 divers are there to help the lifting operation" correctly answer the question "What are the preparations being made to recover the ship?"?

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: "Give examples of materials to which magnets stick to and do not stick to."

OPTIONS:
- no
- yes

Answer: "Glass"

Response: no

American Airlines Flight 11: FAA Awareness. Although the Boston Center air traffic controller realized at an early stage that there was something wrong with American 11, he did not immediately interpret the plane's failure to respond as a sign that it had been hijacked. At 8:14, when the flight failed to heed his instruction to climb to 35,000 feet, the controller repeatedly tried to raise the flight. He reached out to the pilot on the emergency frequency. Though there was no response, he kept trying to contact the aircraft. At 8:21, American 11 turned off its transponder, immediately degrading the information available about the aircraft. The controller told his supervisor that he thought something was seriously wrong with the plane, although neither suspected a hijacking. The supervisor instructed the controller to follow standard procedures for handling a "no radio" aircraft. The controller checked to see if American Airlines could establish communication with American 11. He became even more concerned as its route changed, moving into another sector's airspace. Controllers immediately began to move aircraft out of its path, and asked other aircraft in the vicinity to look for American 11. At 8:24:38, the following transmission came from American 11: American 11: We have some planes. Just stay quiet, and you'll be okay. We are returning to the airport. The controller only heard something unintelligible; he did not hear the specific words "we have some planes." The next transmission came seconds later: American 11: Nobody move. Everything will be okay. If you try to make any moves, you'll endanger yourself and the airplane.

Question: "What did the controller tell the supervisor when he was not able to communicate with the plane? What was he instructed to do?"

Response: "He told the supervisor he couldn't reach anybody and the supervisor said to try again"

Problem: Do not look for the Danteum in the Eternal City. In true Dantean form, politics stood in the way of its construction in 1938. Ironically this literature-inspired building can itself most easily be found in book form. Reading this book I remembered Goethe's quote about frozen music. Did Terragni try to freeze Dante's medieval miracle of song? Certainly a cold-poem seems artistically repulsive. Unflattering comparisons to the lake of Cocytus spring to mind too. While I cannot read Italian, I can read some German. After locating the original quotation I discovered that 'frozen' is a problematic (though common) translation of Goethe's original 'erstarrte.' The verb 'erstarren' more properly means 'to solidify' or 'to stiffen.' This suggests a chemical reaction in which the art does not necessarily chill in the transformation. Nor can simple thawing yield the original work. Like a chemical reaction it requires an artistic catalyst, a muse. Indeed the Danteum is not a physical translation of the Poem. Terragni thought it inappropriate to translate the Comedy literally into a non-literary work. The Danteum would not be a stage set, rather Terragni generated his design from the Comedy's structure, not its finishes.

Question: "Goethe's original "erstarrte" is better translated into what?"

Answer: "Originality"

- no

no
