user: Information:  - Prestressed concrete is a concrete construction material which is placed under compression prior to it supporting any applied loads (i.e. it is "pre" stressed). A more technical definition is ""Structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads."" This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete volume, and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars, and are most commonly made from high-tensile steels, carbon fibre or aramid fibre. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces, and of ductile high-strength steel when subject to tension forces. This can result in improved structural capacity and/or serviceability compared to conventionally reinforced concrete in many situations. Prestressed concrete is used in a wide range of building and civil structures where its improved concrete performance can allow longer spans, reduced structural thicknesses, and material savings to be realised compared to reinforced concrete. Typical applications range through high-rise buildings, residential slabs, foundation systems, bridge and dam structures, silos and tanks, industrial pavements and nuclear containment structures.  - A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.  - A cantilever bridge is a bridge built using cantilevers, structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework.  - This list of cantilever bridges ranks the world 's Cantilever bridges by the length of their main span . A cantilever bridge is a bridge built using cantilevers : structures that project horizontally into space , supported on only one end .  - In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for the links to be two-force members.

*Question*
Information:  - The Army Black Knights, commonly known as Army, is the name of the athletics teams of the United States Military Academy. They participate in NCAA Division I-A as a non-football member of the Patriot League, a Division I Football Bowl Subdivision independent school and a member of Atlantic Hockey, the Collegiate Sprint Football League (men), the Eastern Intercollegiate Gymnastics League (men), the Eastern Intercollegiate Wrestling Association, the Great America Rifle Conference, the National Collegiate Boxing Association, the National Collegiate Paintball Association and the National Intercollegiate Women's Fencing Association. Army is also one of approximately 300 members of the Eastern College Athletic Conference (ECAC).  - Tate Rink is a 2,648 - seat hockey rink in West Point , New York . It is home to the United States Military Academy Black Knights men 's ice hockey team . It was built in as part of the Major Donald W. Holleder Center athletic complex , which also includes Christl Arena . Army 's first game in the arena was October 25 , 1985 , a 5 - 0 win over Ryerson University of Toronto . The first goal scored in the rink was by West Point plebe Vincent McDermott of Braintree , MA who also scored the second goal that evening . The arena is named for the Tate brothers , Joseph S. Tate ' 41 and Frederic H.S. Tate ' 42 , who were both pilots killed in combat in World War II. ( Maj. Holleder ' 56 , the namesake of the complex , was an All - American football and basketball player killed in action in Vietnam in 1967 . ) Before the Holleder Center was built , the Black Knights hockey team used the open - air Smith Rink , which was across Mills Road , where the James K. Herbert Alumni Center now stands .  - Christl Arena is a 5,043-seat, multi-purpose arena in West Point, New York. It was built in 1985 as part of the Major Donald W. Holleder Center, which also houses Tate Rink. It is home to the United States Military Academy's Army Black Knights men's and women's basketball teams. It was named after 1st Lieutenant Edward C. Christl Jr. '44, a former basketball captain who was killed in combat in Austria during World War II. (Maj. Holleder, '56, the namesake of the athletic center, was an All-American football and basketball player killed in combat in Vietnam in 1967.)    After reading the paragraphs above, we are interested in knowing the entity with which 'tate rink' exhibits the relationship of 'occupant'. Find the answer from the choices below.
