Problem: In recent decades, a series of inscribed graphs and pictures have been found at Neolithic sites in China, including Jiahu (c. 6500 BC), Dadiwan and Damaidi from the 6th millennium BC, and Banpo (5th millennium BC). Often these finds are accompanied by media reports that push back the purported beginnings of Chinese writing by thousands of years. However, because these marks occur singly, without any implied context, and are made crudely and simply, Qiu Xigui concluded that "we do not have any basis for stating that these constituted writing nor is there reason to conclude that they were ancestral to Shang dynasty Chinese characters." They do however demonstrate a history of sign use in the Yellow River valley during the Neolithic through to the Shang period.
What may have been found at Neolithic sites in China in recent decades?
The answer is the following: series of inscribed graphs and pictures

Problem: Children working at a young age has been a consistent theme throughout Africa. Many children began first working in the home to help their parents run the family farm. Children in Africa today are often forced into exploitative labour due to family debt and other financial factors, leading to ongoing poverty. Other types of domestic child labour include working in commercial plantations, begging, and other sales such as boot shining. In total, there is an estimated five million children who are currently working in the field of agriculture which steadily increases during the time of harvest. Along with 30 percent of children who are picking coffee, there are an estimated 25,000 school age children who work year round.
How many children in Africa pick coffee?
The answer is the following: 30 percent

Problem: Comcast delivers third-party television programming content to its own customers, and also produces its own first-party content both for subscribers and customers of other competing television services. Fully or partially owned Comcast programming includes Comcast Newsmakers, Comcast Network, Comcast SportsNet, SportsNet New York, MLB Network, Comcast Sports Southeast/Charter Sports Southeast, NBC Sports Network, The Golf Channel, AZN Television, and FEARnet. On May 19, 2009, Disney and ESPN announced an agreement to allow Comcast Corporation to carry the channels ESPNU and ESPN3.

These plans were then put on hold by the U.S. Olympic Committee. The U.S. Olympic Committee and Comcast have ended the plans to create The U.S. Olympic Network.
What network was proposed by Comcast and the US Olympic Committee?
The answer is the following: The U.S. Olympic Network

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 type of aircraft is used to deliver troops and weapons to military operations?
The answer is the following:
Cargo and transport
