Please answer the following question: Information:  - Electricity is a physical phenomenon associated with the presence of electric charge. Although initially considered a phenomenon separate to magnetism, since the development of Maxwell's Equations both are recognized as part of a single phenomenon:electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. In addition, electricity is at the heart of many modern technologies.  - Geography (from Greek , "geographia", literally "earth description") is a field of science devoted to the study of the lands, the features, the inhabitants, and the phenomena of Earth. The first person to use the word "" was Eratosthenes (276194 BC). Geography is an all-encompassing discipline that seeks an understanding of the Earth and its human and natural complexitiesnot merely where objects are, but how they have changed and come to be. It is often defined in terms of the two branches of human geography and physical geography. The four historical traditions in geographical research are: spatial analyses of natural and the human phenomena, area studies of places and regions, studies of human-land relationships, and the Earth sciences. Geography has been called "the world discipline" and "the bridge between the human and the physical sciences".  - The term export means shipping in the goods and services out of the jurisdiction of a country. The seller of such goods and services is referred to as an "exporter" and is based in the country of export whereas the overseas based buyer is referred to as an "importer". In international trade, "exports" refers to selling goods and services produced in the home country to other markets.  - Lightning is a sudden electrostatic discharge that occurs during an electrical storm. This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds (CC lightning), or between a cloud and the ground (CG lightning). The charged regions in the atmosphere temporarily equalize themselves through this discharge referred to as a "strike" if it hits an object on the ground, and a flash, if it occurs within a cloud. Lightning causes light in the form of plasma, and sound in the form of thunder. Lightning may be seen and not heard when it occurs at a distance too great for the sound to carry as far as the light from the strike or flash.  - An economy (From Greek   "household" and o  "manage") is an area of the production, distribution, or trade, and consumption of goods and services by different agents in a given geographical location. Understood in its broadest sense, 'The economy is defined as a social domain that emphasizes the practices, discourses, and material expressions associated with the production, use and management of resources'. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency, but monetary transactions are only a small part of the economic domain.  - The Central Intelligence Agency (CIA) is a civilian foreign intelligence service of the United States federal government, tasked with gathering, processing and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT). As one of the principal members of the U.S. Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet.  - The military, also called the armed forces, are forces authorized to use deadly force, and weapons, to support the interests of the state and some or all of its citizens. The task of the military is usually defined as defense of the state and its citizens, and the prosecution of war against another state. The military may also have additional sanctioned and non-sanctioned functions within a society, including, the promotion of a political agenda, protecting corporate economic interests, internal population control, construction, emergency services, social ceremonies, and guarding important areas. The military can also function as a discrete subculture within a larger civil society, through the development of separate infrastructures, which may include housing, schools, utilities, food production and banking.  - ALMANAC is the name of a major breast cancer trial. The acronym stands for "Axillary Lymphatic Mapping Against Nodal Axillary Clearance." This major randomized trial performed in several centres in the UK produced clear evidence that sentinel node biopsy (SNB), used to stage axillary spread of disease, can be used with low failed localization and false negative rates, provided both radioisotope and blue dye are used to locate the sentinel nodes.  - The World Factbook (also known as the CIA World Factbook) is a reference resource produced by the Central Intelligence Agency with almanac-style information about the countries of the world. The official print version is available from the National Technical Information Service and the Government Printing Office. Other companiessuch as Skyhorse Publishingalso print a paper edition. "The Factbook" is available in the form of a website that is partially updated every week. It is also available for download for use off-line. It provides a two- to three-page summary of the demographics, geography, communications, government, economy, and military of each of 267 international entities including U.S.-recognized countries, dependencies, and other areas in the world.  - This is a list of countries by electricity exports mostly based on The World Factbook .  - Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Like charges repel and unlike attract. An object is negatively charged if it has an excess of electrons, and is otherwise positively charged or uncharged. The SI derived unit of electric charge is the coulomb (C). In electrical engineering, it is also common to use the ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge ("e") as a unit. The symbol "Q" often denotes charge. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that don't require consideration of quantum effects.  - Communication (from Latin "commnicre", meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.  - The world is the planet Earth and all life upon it, including human civilization. In a philosophical context, the world is the whole of the physical Universe, or an ontological world. In a theological context, the "world" is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts.  - Skyhorse Publishing, Inc. is an American independent book publishing company founded in 2006. Headquartered in New York City, its distributor is Perseus Book Group.    Given the information, choose the subject and object entities that have the relation of 'is a list of'.
