Input: What if two children push a swing at the same time? Would the swing go higher? Yes, together their force would be more. It is common for forces to be combined. Most objects on Earth have at least two forces acting on them. Do you know what one of them is? Of course, that force is gravity. How many forces do you have on you right now? Gravity pulls you down toward the center of Earth. Your legs exert a downward force. They hold you up against the pull of gravity. Consider the example in Figure 1.3. A book is resting on a table. Gravity pulls the book downward. It has a force of 20 newtons. At the same time, the table pushes the book upward. Its force is also 20 newtons. The table opposes the pull of gravity.
"How would gravity affect a book resting on a table/" is "The book would be in the air"?

OPTIONS:
- no
- yes
Output: no

Input: Energy often changes from one form to another. For example, the drummer transfers motion to sound energy. When the moving drumstick strikes the drum head, the drum starts to vibrate. The motion of the vibrating drum head creates the sound you hear. Any form of energy can change into any other form. Frequently, one form of energy changes into two or more different forms. Have you ever sat in front of a campfire? What are two things you notice? The fire creates light. It is also warm by the fire, meaning it creates heat. The energy of the fire comes from the stored energy in the wood. The wood contains chemical energy. As it burns, the chemical energy is changed into light and heat. Not all chemical energy changes produce light and heat. Our cars use gasoline as a fuel. Gasoline contains chemical energy. When our cars burn gasoline in their engines, it is converted into motion and heat. When energy changes forms, energy is conserved.

Does the response "The drummer strikes the drumhead, using motion to start the drum vibrating. The motion of the vibrating drum head is transferred to sound energy, which is what you hear" correctly answer the question "How is the sound of a vibrating drum produced by energy?"?

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.

Question: "Who presented the offer of the ceremonial position of president to Einstein?"

Problem: 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.
