Information:  - Saipan is the largest island of the Northern Mariana Islands, a commonwealth of the United States in the western Pacific Ocean. According to the 2010 United States Census, Saipan's population was 48,220.  - The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east.  - Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney.  - The islands were named after Queen Mariana by Spaniards, who first arrived in the early 16th century and who eventually annexed and colonized the archipelago. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated the people who first settled the Marianas arrived there after making what was at that time the longest uninterrupted ocean voyage in human history. They further reported findings which suggested that Tinian is likely to have been the first island in Oceania to have been settled by humans.  - Antarctica (US English , UK English or ) is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At , it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.  - The Americas, also collectively called America, encompass the totality of the continents of North America and South America. Together they make up most of Earth's western hemisphere and comprise the "New World".   - Alamagan is an island in the Northern Mariana Islands in the Pacific Ocean . The island is currently uninhabited . Alamagan is located 30 nautical miles ( 56 km ) north from Guguan and 250 nautical miles ( 463 km ) north from Saipan , and is 60 nautical miles ( 111 km ) south from Pagan .  - The Antarctic (US English , UK English or and or ) is a polar region, specifically the region around the Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises in the strict sense the continent of Antarctica and the island territories located on the Antarctic Plate. In a broader sense the Antarctic region include the ice shelves, waters, and island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20% of the Southern Hemisphere, of which 5.5% (14 million km) is the surface area of the Antarctic continent itself. All of the land and ice shelves south of 60°S latitude are administrated under the Antarctic Treaty System. In a biogeographic sense, the Antarctic ecozone is one of eight ecozones of the Earth's land surface.  - The Northern Mariana Islands, officially the Commonwealth of the Northern Mariana Islands (CNMI Carolinian: "Commonwealth Téél Falúw kka Efáng llól Marianas"), is an insular area and commonwealth of the United States consisting of fifteen islands in the northwestern Pacific Ocean. The CNMI includes all islands in the Mariana Archipelago except Guam, which is the southernmost island of the chain and a separate U.S. territory.  - The Southern Ocean, also known as the Antarctic Ocean or the Austral Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. As such, it is regarded as the fourth-largest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian Oceans but larger than the Arctic Ocean. This ocean zone is where cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters.  - Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people.

Information:  - A firefighter (historically fireman) is a rescuer extensively trained in firefighting, primarily to extinguish hazardous fires that threaten property and civilian or natural populations, and to rescue people from dangerous situations, like collapsed or burning buildings or crashed vehicles. In some areas, they are also trained in Emergency Medical Services (EMS) and operate ambulances in addition to being a firefighter.  - A fire hydrant is an active fire protection measure , and a connection point by which firefighters can tap into a water supply .  - Active fire protection (AFP) is an integral part of fire protection. AFP is characterized by items and/or systems, which require a certain amount of motion and response in order to work, contrary to passive fire protection.  - Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. In structures, be they land-based, offshore or even ships, the owners and operators are responsible to maintain their facilities in accordance with a design-basis that is rooted in laws, including the local building code and fire code, which are enforced by the Authority Having Jurisdiction.    After reading the paragraphs above, we are interested in knowing the entity with which 'fire hydrant' exhibits the relationship of 'use'. Find the answer from the choices below.
