Problem: Please answer a question about the following article about Daylight saving time:
Common agreement about the day's layout or schedule confers so many advantages that a standard DST schedule has generally been chosen over ad hoc efforts to get up earlier. The advantages of coordination are so great that many people ignore whether DST is in effect by altering their nominal work schedules to coordinate with television broadcasts or daylight. DST is commonly not observed during most of winter, because its mornings are darker; workers may have no sunlit leisure time, and children may need to leave for school in the dark. Since DST is applied to many varying communities, its effects may be very different depending on their culture, light levels, geography, and climate; that is why it is hard to make generalized conclusions about the absolute effects of the practice. Some areas may adopt DST simply as a matter of coordination with others rather than for any direct benefits.
What indirect benefit of DST might cause some areas to observe it even though they don't get any direct benefits like cost or energy savings?
A: coordination with others

Question: Read this and answer the question

Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.

How are ways of finding an emulsion's sensitivity possible?
Answer: because reciprocity holds

Problem: Estonian (eesti keel [esti kel] ( listen)) is the official language of Estonia, spoken natively by about 1.1 million people in Estonia and tens of thousands in various migrant communities. It belongs to the Finnic branch of the Uralic language family.

Archaeology is the study of the human past through its material remains. Artifacts, faunal remains, and human altered landscapes are evidence of the cultural and material lives of past societies. Archaeologists examine these material remains in order to deduce patterns of past human behavior and cultural practices. Ethnoarchaeology is a type of archaeology that studies the practices and material remains of living human groups in order to gain a better understanding of the evidence left behind by past human groups, who are presumed to have lived in similar ways.
What do Ethnoarchaeologists gain a better understanding of by studying living human groups?
past human groups

Input: United States presidential election, 2004
The Bush administration then turned its attention to Iraq, and argued the need to remove Saddam Hussein from power in Iraq had become urgent. Among the stated reasons were that Saddam's regime had tried to acquire nuclear material and had not properly accounted for biological and chemical material it was known to have previously possessed, and believed to still maintain. Both the possession of these weapons of mass destruction (WMD), and the failure to account for them, would violate the U.N. sanctions. The assertion about WMD was hotly advanced by the Bush administration from the beginning, but other major powers including China, France, Germany, and Russia remained unconvinced that Iraq was a threat and refused to allow passage of a UN Security Council resolution to authorize the use of force. Iraq permitted UN weapon inspectors in November 2002, who were continuing their work to assess the WMD claim when the Bush administration decided to proceed with war without UN authorization and told the inspectors to leave the country. The United States invaded Iraq on March 20, 2003, along with a "coalition of the willing" that consisted of additional troops from the United Kingdom, and to a lesser extent, from Australia and Poland. Within about three weeks, the invasion caused the collapse of both the Iraqi government and its armed forces, however, the U.S. and allied forces failed to find any weapon of mass destruction in Iraq. Traces of former materials and weapons labs were reported to have been located, but no "smoking guns". Nevertheless, on May 1, George W. Bush landed on the aircraft carrier USS Abraham Lincoln, in a Lockheed S-3 Viking, where he gave a speech announcing the end of "major combat operations" in the Iraq War. Bush's approval rating in May was at 66%, according to a CNNUSA TodayGallup poll. However, Bush's high approval ratings did not last. First, while the war itself was popular in the U.S., the reconstruction and attempted "democratization" of Iraq lost some support as months passed and casualty figures increased, with no decrease in violence nor progress toward stability or reconstruction. Second, as investigators combed through the country, they failed to find the predicted WMD stockpiles, which led to debate over the rationale for the war.

Who did Bush feel was important to remove from power, after removing the Taliban from Kabul?
Output: Saddam Hussein

Problem: Please answer a question about the following article about Dwight D. Eisenhower:
In November 1945, Eisenhower returned to Washington to replace Marshall as Chief of Staff of the Army. His main role was rapid demobilization of millions of soldiers, a slow job that was delayed by lack of shipping. Eisenhower was convinced in 1946 that the Soviet Union did not want war and that friendly relations could be maintained; he strongly supported the new United Nations and favored its involvement in the control of atomic bombs. However, in formulating policies regarding the atomic bomb and relations with the Soviets, Truman was guided by the U.S. State Department and ignored Eisenhower and the Pentagon. Indeed, Eisenhower had opposed the use of the atomic bomb against the Japanese, writing, "First, the Japanese were ready to surrender and it wasn't necessary to hit them with that awful thing. Second, I hated to see our country be the first to use such a weapon." Initially, Eisenhower was characterized by hopes for cooperation with the Soviets. He even visited Warsaw in 1945. Invited by Bolesaw Bierut and decorated with the highest military decoration, he was shocked by the scale of destruction in the city. However, by mid-1947, as EastWest tensions over economic recovery in Germany and the Greek Civil War escalated, Eisenhower gave up and agreed with a containment policy to stop Soviet expansion.
What was Eisenhower's position on the use of nuclear weapons against Japan?
A:
opposed
