Article: The Sahara (Arabic: , as-sahra al-kubra, 'the Greatest Desert') is the largest hot desert in the world. It is the third largest desert after Antarctica and the Arctic. Its surface area of 9,400,000 square kilometres (3,600,000 sq mi)[citation needed]including the Libyan Desertis comparable to the respective land areas of China or the United States. The desert comprises much of the land found within North Africa, excluding the fertile coastal region situated against the Mediterranean Sea, the Atlas Mountains of the Maghreb, and the Nile Valley of Egypt and Sudan. The Sahara stretches from the Red Sea in the east and the Mediterranean in the north, to the Atlantic Ocean in the west, where the landscape gradually transitions to a coastal plain. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions, including the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Air Mountains, the Tenere desert, and the Libyan Desert. Its name is derived from the plural Arabic language word for desert ( sahara [sr]).

Article: Solar cookers use sunlight for cooking, drying and pasteurization. They can be grouped into three broad categories: box cookers, panel cookers and reflector cookers. The simplest solar cooker is the box cooker first built by Horace de Saussure in 1767. A basic box cooker consists of an insulated container with a transparent lid. It can be used effectively with partially overcast skies and will typically reach temperatures of 90150 C (194302 F). Panel cookers use a reflective panel to direct sunlight onto an insulated container and reach temperatures comparable to box cookers. Reflector cookers use various concentrating geometries (dish, trough, Fresnel mirrors) to focus light on a cooking container. These cookers reach temperatures of 315 C (599 F) and above but require direct light to function properly and must be repositioned to track the Sun.

Question: What are the 3 main categories of solar cookers?
Ans: box cookers, panel cookers and reflector cookers

Article: The U.S. census race definitions says a "black" is a person having origins in any of the black (sub-Saharan) racial groups of Africa. It includes people who indicate their race as "Black, African Am., or Negro" or who provide written entries such as African American, Afro-American, Kenyan, Nigerian, or Haitian. The Census Bureau notes that these classifications are socio-political constructs and should not be interpreted as scientific or anthropological. Most African Americans also have European ancestry in varying amounts; a lesser proportion have some Native American ancestry. For instance, genetic studies of African Americans show an ancestry that is on average 1718% European.

Question: What classification are given?
Ans: socio-political constructs
