The problem: Answer a question about this article:
In April 2007, the first satellite of BeiDou-2, namely Compass-M1 (to validate frequencies for the BeiDou-2 constellation) was successfully put into its working orbit. The second BeiDou-2 constellation satellite Compass-G2 was launched on 15 April 2009. On 15 January 2010, the official website of the BeiDou Navigation Satellite System went online, and the system's third satellite (Compass-G1) was carried into its orbit by a Long March 3C rocket on 17 January 2010. On 2 June 2010, the fourth satellite was launched successfully into orbit. The fifth orbiter was launched into space from Xichang Satellite Launch Center by an LM-3I carrier rocket on 1 August 2010. Three months later, on 1 November 2010, the sixth satellite was sent into orbit by LM-3C. Another satellite, the Beidou-2/Compass IGSO-5 (fifth inclined geosynchonous orbit) satellite, was launched from the Xichang Satellite Launch Center by a Long March-3A on 1 December 2011 (UTC).
What is the purpose of the Compass-M1 satellite?
****
The answer: to validate frequencies for the BeiDou-2 constellation

Problem: Please answer a question about the following article about Film speed:
For digital photo cameras ("digital still cameras"), an exposure index (EI) ratingcommonly called ISO settingis specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the camera's parameters for interpreting the sensor data values into sRGB values are fixed, and a number of different EI choices are accommodated by varying the sensor's signal gain in the analog realm, prior to conversion to digital. Some camera designs provide at least some EI choices by adjusting the sensor's signal gain in the digital realm. A few camera designs also provide EI adjustment through a choice of lightness parameters for the interpretation of sensor data values into sRGB; this variation allows different tradeoffs between the range of highlights that can be captured and the amount of noise introduced into the shadow areas of the photo.
How do some camera designs give some EI choices?
A: by adjusting the sensor's signal gain in the digital realm

After the American Revolutionary War, the number and proportion of free people of color increased markedly in the North and the South as slaves were freed. Most northern states abolished slavery, sometimes, like New York, in programs of gradual emancipation that took more than two decades to be completed. The last slaves in New York were not freed until 1827. In connection with the Second Great Awakening, Quaker and Methodist preachers in the South urged slaveholders to free their slaves. Revolutionary ideals led many men to free their slaves, some by deed and others by will, so that from 1782 to 1810, the percentage of free people of color rose from less than one percent to nearly 10 percent of blacks in the South.

What caused Quaker and Methodist preachers to want to free slaves?
Answer: Second Great Awakening

Problem: Cargo and transport aircraft are typically used to deliver troops, weapons and other military equipment by a variety of methods to any area of military operations around the world, usually outside of the commercial flight routes in uncontrolled airspace. The workhorses of the USAF Air Mobility Command are the C-130 Hercules, C-17 Globemaster III, and C-5 Galaxy. These aircraft are largely defined in terms of their range capability as strategic airlift (C-5), strategic/tactical (C-17), and tactical (C-130) airlift to reflect the needs of the land forces they most often support. The CV-22 is used by the Air Force for the U.S. Special Operations Command (USSOCOM). It conducts long-range, special operations missions, and is equipped with extra fuel tanks and terrain-following radar. Some aircraft serve specialized transportation roles such as executive/embassy support (C-12), Antarctic Support (LC-130H), and USSOCOM support (C-27J, C-145A, and C-146A). The WC-130H aircraft are former weather reconnaissance aircraft, now reverted to the transport mission.
What aircraft are considered the workhorses of the US Air Force?
The answer is the following: C-130 Hercules, C-17 Globemaster III, and C-5 Galaxy

Many students are involved in community service in one form or another. Annual events include Dance Marathon, a thirty-hour event that raised more than a million dollars for charity in 2011; and Project Pumpkin, a Halloween celebration hosted by the Northwestern Community Development Corps (NCDC) to which more than 800 local children are invited for an afternoon of games and sweets. NCDC's work is to connect hundreds of student volunteers to some twenty volunteer sites in Evanston and Chicago throughout the year. Many students have assisted with the Special Olympics and have taken alternative spring break trips to hundreds of service sites across the United States. Northwestern students also participate in the Freshman Urban Program, a program for students interested in community service. A large and growing number of students participate in the university's Global Engagement Summer Institute (GESI), a group service-learning expedition in Asia, Africa, or Latin America, in conjunction with the Foundation for Sustainable Development. Several internationally recognized non-profit organizations have originated at Northwestern including the World Health Imaging, Informatics and Telemedicine Alliance, a spin-off from an engineering student's honors thesis.
What is the name of the Northwestern program for students interested in community service?
Freshman Urban Program

Here is a question about this article: Following the 1967 war and the "three nos" resolution of the Arab League, during the 19671970 War of Attrition Israel faced attacks from the Egyptians in the Sinai, and from Palestinian groups targeting Israelis in the occupied territories, in Israel proper, and around the world. Most important among the various Palestinian and Arab groups was the Palestinian Liberation Organization (PLO), established in 1964, which initially committed itself to "armed struggle as the only way to liberate the homeland". In the late 1960s and early 1970s, Palestinian groups launched a wave of attacks against Israeli and Jewish targets around the world, including a massacre of Israeli athletes at the 1972 Summer Olympics in Munich. The Israeli government responded with an assassination campaign against the organizers of the massacre, a bombing and a raid on the PLO headquarters in Lebanon.
What is the answer to this question: What did the ELO commit itself on?
****
So...
armed struggle as the only way to liberate the homeland
