This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Passage: Returning to the basic concept of current flows in a conductor, consider what happens if a half-wave dipole is not connected to a feed point, but instead shorted out. Electrically this forms a single 1⁄2-wavelength element. But the overall current pattern is the same; the current will be zero at the two ends, and reach a maximum in the center. Thus signals near the design frequency will continue to create a standing wave pattern. Any varying electrical current, like the standing wave in the element, will radiate a signal. In this case, aside from resistive losses in the element, the rebroadcast signal will be significantly similar to the original signal in both magnitude and shape. If this element is placed so its signal reaches the main dipole in-phase, it will reinforce the original signal, and increase the current in the dipole. Elements used in this way are known as passive elements. Question: What is a half wave dipole need to be coupled with in most instances?
feed point

Passage: Every fall the Santa Monica Chamber of Commerce hosts The Taste of Santa Monica on the Santa Monica Pier. Visitors can sample food and drinks from Santa Monica restaurants. Other annual events include the Business and Consumer Expo, Sustainable Quality Awards, Santa Monica Cares Health and Wellness Festival, and the State of the City. The swanky Shutters on the Beach Hotel offers a trip to the famous Santa Monica Farmers Market to select and influence the materials that will become that evening's special "Market Dinner." Question: Where is the Taste of Santa Monica held each year?
Santa Monica Pier

Passage: A police force is a constituted body of persons empowered by the state to enforce the law, protect property, and limit civil disorder. Their powers include the legitimized use of force. The term is most commonly associated with police services of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from military or other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Question: What are police usually separate from?

military or other organizations involved in the defense of the state against foreign aggressors
