input: Please answer the following: Information:  - Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between and . This broad definition includes both UHF and EHF (millimeter wave) bands, and various sources use different boundaries. In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum, with RF engineering often restricting the range between 1 and 100 GHz (300 and 3 mm). Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, K, K, or K band, or by similar NATO or EU designations.  - In physics, energy is the property that must be transferred to an object in order to perform work on  or to heat  the object, and can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton.  - Physics (from , from "phúsis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.  - Percy Lebaron Spencer ( 19 July 1894 -- 8 September 1970 ) was an American physicist and inventor . He became known as the inventor of the microwave oven .  - An oven is a thermally insulated chamber used for the heating, baking or drying of a substance, and most commonly used for cooking. Kilns and furnaces are special-purpose ovens, used in pottery and metalworking, respectively.  - A microwave oven (commonly referred to as a microwave) is a kitchen appliance that heats and cooks food by exposing it to microwave radiation in the electromagnetic spectrum. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer of a homogeneous, high water content food item; food is more evenly heated throughout (except in heterogeneous, dense objects) than generally occurs in other cooking techniques.  - A physicist is a scientist who has specialized knowledge in the field of physics, the exploration of the interactions of matter and energy across the physical universe.    Given the paragraphs above, decide what entity has the relation 'place of death' with 'newton'.

input: Please answer the following: Information:  - A teacher (also called a school teacher or, in some contexts, an educator) is a person who helps others to acquire knowledge, competences or values.  - Dennis Van Roekel is an American labor leader who served as president of the National Education Association , the largest labor union in the United States .  - The National Education Association (NEA) is the largest labor union in the United States. It represents public school teachers and other support personnel, faculty and staffers at colleges and universities, retired educators, and college students preparing to become teachers. The NEA has just under 3 million members and is headquartered in Washington, D.C. The NEA had a budget of more than $341 million for the 20122013 fiscal year. Lily Eskelsen García is the NEA's current president.    Given the paragraphs above, decide what entity has the relation 'occupation' with 'teacher'.
