Input: It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place.

Does the response "Magnetic north." correctly answer the question "What does the magnet in a compass point toward?"?

The Vice President stated that he called the President to discuss the rules of engagement for the CAP. He recalled feeling that it did no good to establish the CAP unless the pilots had instructions on whether they were authorized to shoot if the plane would not divert. He said the President signed off on that concept. The President said he remembered such a conversation, and that it reminded him of when he had been an interceptor pilot. The President emphasized to us that he had authorized the shootdown of hijacked aircraft. The Vice President's military aide told us he believed the Vice President spoke to the President just after entering the conference room, but he did not hear what they said. Rice, who entered the room shortly after the Vice President and sat next to him, remembered hearing him inform the President, "Sir, the CAPs are up. Sir, they're going to want to know what to do." Then she recalled hearing him say, "Yes sir." She believed this conversation occurred a few minutes, perhaps five, after they entered the conference room. We believe this call would have taken place sometime before 10:10 to 10:15. Among the sources that reflect other important events of that morning, there is no documentary evidence for this call, but the relevant sources are incomplete. Others nearby who were taking notes, such as the Vice President's chief of staff, Scooter Libby, who sat next to him, and Mrs. Cheney, did not note a call between the President and Vice President immediately after the Vice President entered the conference room. At 10:02, the communicators in the shelter began receiving reports from the Secret Service of an inbound aircraft-presumably hijacked-heading toward Washington. That aircraft was United 93. The Secret Service was getting this information directly from the FAA. The FAA may have been tracking the progress of United 93 on a display that showed its projected path to Washington, not its actual radar return. Thus, the Secret Service was relying on projections and was not aware the plane was already down in Pennsylvania.

If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Question: "Is any matter destroyed when you burn wood in a campfire?"

Response: "No, because of conservation of mass"
OPTIONS:
- no
- yes

Problem: 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.

Question: "How does one buy durable goods to reduce resource use?"

Answer: "Buy from reputable sellers"

The Albanians first appear in the historical record in Byzantine sources of the late 11th century. At this point, they were already fully Christianized. Islam later emerged as the majority religion during the centuries of Ottoman rule, though a significant Christian minority remained. After independence (1912) from the Ottoman Empire, the Albanian republican, monarchic and later Communist regimes followed a systematic policy of separating religion from official functions and cultural life. Albania never had an official state religion either as a republic or as a kingdom. In the 20th century, the clergy of all faiths was weakened under the monarchy, and ultimately eradicated during the 1950s and 1960s, under the state policy of obliterating all organized religion from Albanian territories. The Communist regime that took control of Albania after World War II persecuted and suppressed religious observance and institutions and entirely banned religion to the point where Albania was officially declared to be the world's first atheist state. Religious freedom has returned to Albania since the regime's change in 1992. Albania joined the Organisation of the Islamic Conference in 1992, following the fall of the communist government, but will not be attending the 2014 conference due a dispute regarding the fact that its parliament never ratified the country's membership. Albanian Muslim populations (mainly secular and of the Sunni branch) are found throughout the country whereas Albanian Orthodox Christians as well as Bektashis are concentrated in the south and Roman Catholics are found in the north of the country. The first recorded Albanian Protestant was Said Toptani, who traveled around Europe, and in 1853 returned to Tirana and preached Protestantism. He was arrested and imprisoned by the Ottoman authorities in 1864. Mainline evangelical Protestants date back to the work of Congregational and later Methodist missionaries and the work of the British and Foreign Bible Society in the 19th century. The Evangelical Alliance, which is known as VUSh, was founded in 1892. Today VUSh has about 160 member congregations from different Protestant denominations. VUSh organizes marches in Tirana including one against blood feuds in 2010. Bibles are provided by the Interconfessional Bible Society of Albania. The first full Albanian Bible to be printed was the Filipaj translation printed in 1990.

Question: "By when were the Albanians fully Christianized?"

Response: "Late 10th"
