Information: - Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets. - The European Space Agency (ESA ASE) is an intergovernmental organisation dedicated to the exploration of space, with 22 member states. Established in 1975 and headquartered in Paris, France, ESA has a worldwide staff of about 2,000 and an annual budget of about 5.25 billion / US$5.77 billion (2016). - Copernicus is the world's largest single earth observation programme and directed by the European Commission in partnership with the European Space Agency (ESA). It aims at achieving a global, continuous, autonomous, high quality, wide range Earth observation capacity. Providing accurate, timely and easily accessible information to, among other things, improve the management of the environment, understand and mitigate the effects of climate change, and ensure civil security. It follows and greatly expands on the work of the previous 2.3 billion euros European Envisat program which operated from 2002 to 2012. - Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. Remote sensing is used in numerous fields, including geography and most Earth Science disciplines (for example, hydrology, ecology , oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications. - The European Commission (EC) is an institution of the European Union, responsible for proposing legislation, implementing decisions, upholding the EU treaties and managing the day-to-day business of the EU. Commissioners swear an oath at the European Court of Justice in Luxembourg, pledging to respect the treaties and to be completely independent in carrying out their duties during their mandate. - The natural environment encompasses all living and non-living things occurring naturally. The term is most often applied to the Earth or some part of Earth. This environment encompasses the interaction of all living species, climate, weather, and natural resources that affect human survival and economic activity. - In social science, the term built environment refers to the man-made surroundings that provide the setting for human activity, ranging in scale from buildings and parks. It has been defined as "the humanitarian-made space in which people live, work, and recreate on a day-to-day basis." The "built environment encompasses places and spaces created or modified by people including buildings, parks, and transportation systems." In recent years, public health research has expanded the definition of "built environment" to include healthy food access, community gardens,mental health, "walkability" and "bikeability." - Sentinel - 2 is an Earth observation mission developed by ESA as part of the Copernicus Programme to perform terrestrial observations in support of services such as forest monitoring , land cover changes detection , and natural disaster management . It consists of two identical satellites , Sentinel - 2A and Sentinel - 2B . - Earth observation (EO) is the gathering of information about planet Earth's physical, chemical and biological systems via remote sensing technologies supplemented by earth surveying techniques, encompassing the collection, analysis and presentation of data. Earth observation is used to monitor and assess the status of, and changes in, the natural environment and the built environment. In recent years, Earth observation has become technologically increasingly sophisticated. It has also become more important due to the dramatic impact that modern human civilization is having on the planet Earth, and the need to minimize negative impacts along with the opportunities Earth observation provides to improve social and economic well-being. - Envisat ("Environmental Satellite") is a large inactive Earth-observing satellite which is still in orbit. Operated by the European Space Agency (ESA), it was the world's largest civilian Earth observation satellite. After reading the paragraphs above, we are interested in knowing the entity with which 'sentinel-2' exhibits the relationship of 'subclass of'. Find the answer from the choices below. Choices: - activity - agency - change - civilization - climate - collection - community - court - data - earth observation satellite - ecology - european commission - exploration - information - institution - interaction - life - member - military - monitor - natural - natural environment - observation - out - partnership - planet - planning - public - remote sensing - satellite - security - setting - single - social science - space - species - status - surveying - term - third - world
