TASK DEFINITION: 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.
PROBLEM: 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?

SOLUTION: feed point

PROBLEM: Passage: In its early years Universal released three brands of feature films — Red Feather, low-budget programmers; Bluebird, more ambitious productions; and Jewel, their prestige motion pictures. Directors included Jack Conway, John Ford, Rex Ingram, Robert Z. Leonard, George Marshall and Lois Weber, one of the few women directing films in Hollywood.:13 Question: What sort of films were produced by Red Feather?

SOLUTION: low-budget programmers

PROBLEM: Passage: On 8 February 1963, a military coup in Iraq led by a Ba'athist–Nasserist alliance toppled Qasim, who was subsequently shot dead. Abdel Salam Aref, a Nasserist, was chosen to be the new president. A similar alliance toppled the Syrian government on 8 March. On 14 March, the new Iraqi and Syrian governments sent Nasser delegations to push for a new Arab union. At the meeting, Nasser lambasted the Ba'athists for "facilitating" Syria's split from the UAR, and asserted that he was the "leader of the Arabs". A transitional unity agreement stipulating a federal system was signed by the parties on 17 April and the new union was set to be established in May 1965. However, the agreement fell apart weeks later when Syria's Ba'athists purged Nasser's supporters from the officers corps. A failed counter-coup by a Nasserist colonel followed, after which Nasser condemned the Ba'athists as "fascists". Question: What groups completed a coup in Iraq?

SOLUTION:
Ba'athist–Nasserist alliance
