Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice.

Question: "What are glaciers and what affect do they have on land?"

Response: "The massive ice sheet, called a glacier, caused the features on the land"

- no

Problem: As his car slid downtown on Tuesday morning the mind of Arnold Thorndike was occupied with such details of daily routine as the purchase of a railroad, the Japanese loan, the new wing to his art gallery, and an attack that morning, in his own newspaper, upon his pet trust. But his busy mind was not too occupied to return the salutes of the traffic policemen who cleared the way for him. Or, by some genius of memory, to recall the fact that it was on this morning young Spear was to be sentenced for theft. It was a charming morning. The spring was at full tide, and the air was sweet and clean. Mr. Thorndike considered whimsically that to send a man to jail with the memory of such a morning clinging to him was adding a year to his sentence. He regretted he had not given the probation officer a stronger letter. He remembered the young man now, and favorably. A shy, silent youth, deft in work, and at other times conscious and embarrassed. But that, on the part of a stenographer, in the presence of the Wisest Man in Wall Street, was not unnatural. On occasions, Mr. Thorndike had put even royalty frayed, impecunious royalty, on the lookout for a loanat its ease. The hood of the car was down, and the taste of the air, warmed by the sun, was grateful. It was at this time, a year before, that young Spear picked the spring flowers to take to his mother. A year from now where would young Spear be? It was characteristic of the great man to act quickly, so quickly that his friends declared he was a slave to impulse. It was these same impulses, leading so invariably to success, that made his enemies call him the Wisest Man. He leaned forward and touched the chauffeur's shoulder. "Stop at the Court of General Sessions," he commanded. What he proposed to do would take but a few minutes. A word, a personal word from him to the district attorney, or the judge, would be enough.

Question: "What is the Wisest Man's name?"

Answer: "Arnold Spear"

Question:
Crusaders, Mamelukes, and Turks: The Crusaders established a feudal Christian state with Godfrey at its head. They built many impressive churches during the term of the first Latin Kingdom of Jerusalem, but in 1187 they were driven out by Muslim forces under the great warrior Saladin. During the Sixth Crusade (1228 1229), the Holy Roman Emperor Frederick II managed to secure Jerusalem for the Christians by negotiation. The Christians, however, could not hold the city. After they lost Jerusalem, a Mongol invasion swept through, and in 1244 the Mameluke dynasty of Egypt took control, ruling Jerusalem for the next 250 years. The city struggled to rebuild from Crusader wars and invasions. Much of the best Islamic architecture in the city was constructed in the Mameluke era, but the past thousand years had taken their toll: Jerusalem was unable to regain the prosperity it had enjoyed in earlier times. In the early 16th century, the Ottoman Turkish Empire was advancing through the Middle East. Jerusalem fell to the Ottomans in 1517, remaining under their control for 400 years. Suleiman the Magnificent rebuilt the walls and gates in the form they retain to this day. Fountains, inns, religious schools, and barracks were constructed. But when Suleiman died, his empire, including Jerusalem, began a long period of decline. The Holy City remained a backwater until the 19th century, when renewed interest among Christian pilgrims made it the destination of thousands of travelers each year. After reading the above, is "The Mameluke Dynasty took control of Jerusalem" the correct answer to the question "What happened during the Sixth Crusade with the Christians?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Reducing resource use means just what it says using fewer resources. There are lots of ways to reduce our use of resources. Buy durable goods. Choose items that are well made so they will last longer. Youll buy fewer items in the long run, so youll save money as well as resources. Thats a win-win! Repair rather than replace. Fix your bike rather than buying a new one. Sew on a button instead of buying a new shirt. Youll use fewer resources and save money. Buy only what you need. Dont buy a gallon of milk if you can only drink half of it before it spoils. Instead, buy a half gallon and drink all of it. You wont be wasting resources (or money!) Buy local. For example, buy local produce at a farmers market, like the one in Figure 2.20. A lot of resources are saved by not shipping goods long distances. Products bought at farmers markets use less packaging, too! About a third of what we throw out is packaging.

Does the response "Share what you have" correctly answer the question "How does buying only what you need to avoid resource waste?"?

OPTIONS:
- no
- yes
