A Yagi-Uda array uses passive elements to greatly increase gain. It is built along a support boom that is pointed toward the signal, and thus sees no induced signal and does not contribute to the antenna's operation. The end closer to the source is referred to as the front. Near the rear is a single active element, typically a half-wave dipole or folded dipole. Passive elements are arranged in front (directors) and behind (reflectors) the active element along the boom. The Yagi has the inherent quality that it becomes increasingly directional, and thus has higher gain, as the number of elements increases. However, this also makes it increasingly sensitive to changes in frequency; if the signal frequency changes, not only does the active element receive less energy directly, but all of the passive elements adding to that signal also decrease their output as well and their signals no longer reach the active element in-phase.

What can take advantage of these elements to add more gain?
Answer: Yagi-Uda array

Problem: Traits valued in women of the samurai class were humility, obedience, self-control, strength, and loyalty. Ideally, a samurai wife would be skilled at managing property, keeping records, dealing with financial matters, educating the children (and perhaps servants, too), and caring for elderly parents or in-laws that may be living under her roof. Confucian law, which helped define personal relationships and the code of ethics of the warrior class required that a woman show subservience to her husband, filial piety to her parents, and care to the children. Too much love and affection was also said to indulge and spoil the youngsters. Thus, a woman was also to exercise discipline.
Who did samurai wives have to teach?
The answer is the following: the children (and perhaps servants, too)

On June 17, 2015, 21-year-old Dylann Roof entered the historic Emanuel African Methodist Episcopal Church during a Bible study and killed nine people. Senior pastor Clementa Pinckney, who also served as a state senator, was among those killed during the attack. The deceased also included congregation members Susie Jackson, 87; Rev. Daniel Simmons Sr., 74; Ethel Lance, 70; Myra Thompson, 59; Cynthia Hurd, 54; Rev. Depayne Middleton-Doctor, 49; Rev. Sharonda Coleman-Singleton, 45; and Tywanza Sanders, 26. The attack garnered national attention, and sparked a debate on historical racism, Confederate symbolism in Southern states, and gun violence. On July 10, 2015, the Confederate battle flag was removed from the South Carolina State House. A memorial service on the campus of the College of Charleston was attended by President Barack Obama, Michelle Obama, Vice President Joe Biden, Jill Biden, and Speaker of the House John Boehner.
Clementa Pinckney served what public office for the state of South Carolina?
state senator

Input: CBC Television
The CBC's flagship newscast, The National, airs Sunday through Fridays at 10:00 p.m. EST and Saturdays at 6:00 p.m. EST. Until October 2006, CBC owned-and-operated stations aired a second broadcast of the program at 11:00 p.m.; this later broadcast included only the main news portion of the program, and excluded the analysis and documentary segment. This second airing was later replaced with other programming, and as of the 2012-13 television season, was replaced on CBC's major market stations by a half-hour late newscast. There is also a short news update, at most, on late Saturday evenings. During hockey season, this update is usually found during the first intermission of the second game of the doubleheader on Hockey Night in Canada.

Which title is CBC's flagship newscast?
Output: The National

Input: Article: In the years following the mid-1930s, Detroit was referred to as the "City of Champions" after the Tigers, Lions, and Red Wings captured all three major professional sports championships in a seven-month period of time (the Tigers won the World Series in October 1935; the Lions won the NFL championship in December 1935; the Red Wings won the Stanley Cup in April 1936). In 1932, Eddie "The Midnight Express" Tolan from Detroit won the 100- and 200-meter races and two gold medals at the 1932 Summer Olympics. Joe Louis won the heavyweight championship of the world in 1937.

Problem: Cotton remained a key crop in the Southern economy after emancipation and the end of the Civil War in 1865. Across the South, sharecropping evolved, in which landless black and white farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs themselves. Until mechanical cotton pickers were developed, cotton farmers needed additional labor to hand-pick cotton. Picking cotton was a source of income for families across the South. Rural and small town school systems had split vacations so children could work in the fields during "cotton-picking."
What function of southern schools was created for children to pick cotton?
The answer is the following:
split vacations
