Document 3: Betty Applewhite: Regarding Betty Applewhite and the mystery storyline of her family, series creator Marc Cherry stated: "They come on the street; they seem like nice people — but they've got a secret. And it's pretty gothic. It's real and human and awful all at the same time." Woodard commented that her character "never means harm... Let's just say she has flaws. She had to make some really tough decisions quick and if the law ever catches up with her, she'll have to serve time... But they'll never catch her." The final scene in which Betty and Matthew bring food to the prisoner in their basement was originally intended for the first season finale but saved for "Next" instead. While the Applewhites are regarded as the first major black characters on the series, Cherry stated that the role of Betty was originally offered to two white film actresses, both of whom turned it down due to financial and time commitment issues. He clarified: "There's nothing strategically black about her character. Her color is incidental." Woodard stated that she had never seen the show before accepting the role, something that led the producers to send her fifteen episodes of the show, which she divided amongst various family members. After they compared storylines, Woodard recalled that she became "instantly hooked" on the series.
Document 4: Men's major golf championships: The majors originally consisted of two British tournaments, The Open Championship and The Amateur Championship, and two American tournaments, the U.S. Open and the U.S. Amateur. With the introduction of the Masters Tournament in 1934, and the rise of professional golf in the late 1940s and 1950s, the term ``major championships ''eventually came to describe the Masters, the U.S. Open, the Open Championship, and the PGA Championship. It is difficult to determine when the definition changed to include the current four tournaments, although many trace it to Arnold Palmer's 1960 season. After winning the Masters and the U.S. Open to start the season, he remarked that if he could win the Open Championship and PGA Championship to finish the season, he would complete`` a grand slam of his own'' to rival Bobby Jones's 1930 feat. Until that time, many U.S. players such as Byron Nelson also considered the Western Open and the North and South Open as two of golf's ``majors, ''and the British PGA Matchplay Championship was as important to British and Commonwealth professionals as the PGA Championship was to Americans.
Document 5: History of tennis: In 1968, commercial pressures and rumors of some amateurs taking money under the table led to the abandonment of this distinction, inaugurating the Open Era (see below), in which all players could compete in all tournaments, and top players were able to make their living from tennis.

Document 11: Canadian Open (golf): In the mid-1990s, the RCGA decided to move the championship around the country, and continues to alternate between Glen Abbey and other clubs. The owner since 2005, Clublink Corp filed an application in October 2015 to redevelop the property into a residential community, with offices and retail stores. There was no provision for a golf course in the plan. The Town of Oakville Council responded in August 2017 by declaring the golf course a heritage site under the Ontario Heritage Act. This would make it more difficult for ClubLink to develop the area as it had planned. Golf Canada was also concerned since it could not predict whether it could get the necessary permit to hold the Canadian Open at Glen Abbey in 2018 as it had planned. The dispute between the Town of Oakville and ClubLink remains before the provincial appeal tribunal. Due to this situation, the Open will be held at Hamilton Golf and Country Club in 2019.
