Mariah Carey was born in Huntington, New York. Her father, Alfred Roy Carey, was of African American and Afro-Venezuelan descent, while her mother, Patricia (nee Hickey), is of Irish descent. The last name Carey was adopted by her Venezuelan grandfather, Francisco Nunez, after he came to New York. Patricia was an occasional opera singer and vocal coach before she met Alfred in 1960.
Carey possesses a five-octave vocal range, and has the ability to reach notes beyond the 7th octave. Referred to as the "songbird supreme" by the Guinness World Records, she was ranked first in a 2003 MTV and Blender magazine countdown of the 22 Greatest Voices in Music, as voted by fans and readers in an online poll. Carey said of the poll, "What it really means is voice of the MTV generation. Of course, it's an enormous compliment, but I don't feel that way about myself." She also placed second in Cove magazine's list of "The 100 Outstanding Pop Vocalists." Regarding her voice type, Carey said that she is an alto, though several critics have described her as a Coloratura soprano. The singer claims that she has nodules in her vocal cords since childhood, due to which she can sing in a higher register than others. However, tiredness and sleep deprivation can affect her vocals due to the nodules, and Carey explained that she went through a lot of practice to maintain a balance during singing. Jon Pareles of The New York Times described Carey's lower register as a "rich, husky alto" that extends to "dog-whistle high notes." Additionally, towards the late 1990s, Carey began incorporating breathy vocals into her material. Tim Levell from the BBC News described her vocals as "sultry close-to-the-mic breathiness," while USA Today's Elysa Gardner wrote "it's impossible to deny the impact her vocal style, a florid blend of breathy riffing and resonant belting, has had on today's young pop and R&B stars." Sasha Frere-Jones of The New Yorker adds her timbre possesses various colors, saying, "Carey's sound changes with nearly every line, mutating from a steely tone to a vibrating growl and then to a humid, breathy coo. Her wide vocal range allows Carey to take melodies from alto bottom notes to coloratura soprano upper register." Carey also possesses a "whisper register." In an interview with the singer, Ron Givens of Entertainment Weekly described it this way, "first, a rippling, soulful ooh comes rolling effortlessly from her throat: alto. Then, after a quick breath, she goes for the stratosphere, with a sound that nearly changes the barometric pressure in the room. In one brief swoop, she seems to squeal and roar at the same time." Her sense of pitch is admired and Jon Pareles adds "she can linger over sensual turns, growl with playful confidence, syncopate like a scat singer... with startlingly exact pitch."

Has she ever sung any opera?

Lyndon Baines Johnson (; August 27, 1908 - January 22, 1973), often referred to by his initials LBJ, was an American politician who served as the 36th President of the United States from 1963 to 1969, assuming the office after having served as the 37th Vice President of the United States from 1961 to 1963. A Democrat from Texas, he also served as a United States Representative and as the Majority Leader in the United States Senate. Johnson is one of only four people who have served in all four federal elected positions.
In 1964, at Johnson's request, Congress passed the Revenue Act of 1964 and the Economic Opportunity Act, as part of the war on poverty. Johnson set in motion legislation creating programs such as Head Start, food stamps and Work Study. During Johnson's years in office, national poverty declined significantly, with the percentage of Americans living below the poverty line dropping from 23 percent to 12 percent. Johnson took an additional step in the War on Poverty with an urban renewal effort, presenting to Congress in January 1966 the "Demonstration Cities Program". To be eligible a city would need to demonstrate its readiness to "arrest blight and decay and make substantial impact on the development of its entire city." Johnson requested an investment of $400 million per year totaling $2.4 billion. In the fall of 1966 the Congress passed a substantially reduced program costing $900 million, which Johnson later called the Model Cities Program. Changing the name had little effect on the success of the bill; the New York Times wrote 22 years later that the program was for the most part a failure. Johnson's initial effort to improve healthcare was the creation of The Commission on Heart Disease, Cancer and Strokes (HDCS). Combined, these diseases accounted for 71 percent of the nation's deaths in 1962. To enact recommendations of the commission, Johnson asked Congress for funds to set up the Regional Medical Program (RMP), to create a network of hospitals with federally funded research and practice; Congress passed a significantly watered down version. As a back-up position, in 1965 Johnson turned his focus to hospital insurance for the aged under Social Security. The key player in initiating this program, named Medicare, was Wilbur Mills, Chairman of the House Ways and Means Committee. In order to reduce Republican opposition, Mills suggested that Medicare be fashioned as a three layer cake--hospital insurance under Social Security, a voluntary insurance program for doctor visits and an expanded medical welfare program for the poor, known as Medicaid. The bill passed the house by a margin of 110 votes on April 8. The effort in the Senate was considerably more complicated; however, the Medicare bill passed Congress on July 28 after negotiation in a conference committee. Medicare now covers tens of millions of Americans. Johnson gave the first two Medicare cards to former President Harry S Truman and his wife Bess after signing the Medicare bill at the Truman Library in Independence, Missouri.

What did these Act's include?
Johnson set in motion legislation creating programs such as Head Start, food stamps and Work Study.
