In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Martin O'Donnell confirmed Halo 3's soundtrack would see a commercial release in a Bungie podcast. O'Donnell also stressed that the soundtrack would not be released at or near the release date of the game on September 25, 2007. The soundtrack was officially announced on October 17, 2007.
The score to the game was used extensively for marketing purposes, even before the release of the game. The first piece heard was entitled "Finish the Fight", and was used in the announcement trailer for Halo 3 at Electronic Entertainment Expo 2006. This piece was accented with O'Donnell's well-known Halo theme, which now included a trumpet fanfare and heavy brass section; O'Donnell stated "I want the viewer to have a feeling of anticipation and wonder for the first fifty seconds or so, up until Master Chief is revealed and they realize that it's Cortana trying to tell them something." The track opens with a piano section written by Matt Daspit, uncharacteristic for the series at that point; O'Donnell suspected "no [other announcement at E3] would start with a piano", thus grabbing attention. O'Donnell designed the opening to lull the listener into a sense of suspense, then wonder; "I want them to feel pride and longing the moment Master Chief walks out of the smoke." he said. "I want them to be left with that, 'I can hardly wait to play this game' feeling". Another reworked theme from Halo was used as the background music for the Halo 3 E3 2007 trailer; O'Donnell later offered this track for free online.In addition to the music composed by O'Donnell and Salvatori, the announcement of the Halo 3 Soundtrack was followed with a call for entries to all artists or bands to submit their own original song to be included on the final CD. The submissions were judged by O'Donnell, producer Nile Rodgers, and other artists including Steve Vai. Rodgers stated that more than 21,000 songs were entered, and at least 30% were "amazing"; the winner was Greg Haupt and his band Princeton, whose song "LvUrFR3NZ" appears as the final track on the second disc.
What was the date Halo 3's soundtrack was released?

Passage: Aaliyah Dana Haughton was born on January 16, 1979, in Brooklyn, New York, and was the younger child of Diane and Michael "Miguel" Haughton (1951–2012). She was of African-American descent, and had Native American (Oneida) heritage from a grandmother. Her name has been described as a female version of the Arabic "Ali", but the original Jewish name "Aliya (Hebrew: אליה)" is derived from the Hebrew word "aliyah (Hebrew: עלייה)", meaning "highest, most exalted one, the best." The singer was highly fond of her Semitic name, calling it "beautiful" and asserting she was "very proud of it" and strove to live up to her name every day. Aaliyah's mother enrolled Aaliyah in voice lessons at an early age. She started performing at weddings, church choir and charity events. When Aaliyah was five years old, her family moved to Detroit, Michigan, where she was reared along with her older brother, Rashad. She attended a Catholic school, Gesu Elementary, where in first grade she was cast in the stage play Annie, which inspired her to become an entertainer. In Detroit, her father began working in the warehouse business, one of his brother-in-law Barry Hankerson's widening interests. Her mother stayed home and raised Aaliyah and her brother.Throughout Aaliyah’s life, she had a good relationship with Rashad, who recalled Aaliyah having a beautiful voice as a child. Aaliyah's family was very close due to the struggles of her grandparents and when they moved to Detroit, the Hankersons were ready to take them in if necessary. These same bonds led to ties in the music industry, under the Blackground Records label.Aaliyah's mother was a vocalist, and her uncle, Barry Hankerson, was an entertainment lawyer who had been married to Gladys Knight. As a child, Aaliyah traveled with Knight and worked with an agent in New York to audition for commercials and television programs, including Family Matters; she went on to appear on Star Search at the age of ten. Aaliyah chose to begin auditioning. Her mother made the decision to drop her surname. She auditioned for several record labels and at age 11 appeared in concerts alongside Knight. She had several pet animals during her childhood, including ducks, snakes and iguanas. Her cousin Jomo had a pet alligator, which Aaliyah felt was too much, remarking, "that was something I wasn't going to stroke."Her grandmother died in 1991. Years after her death, Aaliyah said her grandmother supported everyone in the family and always wanted to hear her sing, as well as admitting that she "spoiled" her and her brother Rashad. She also enjoyed Aaliyah's singing and would have Aaliyah to sing for her. Aaliyah said she thought of her grandmother whenever she fell into depression. Aaliyah's hands reminded her of her aunt, who died when she was very young and whom Aaliyah remembered as an "amazingly beautiful woman".

What is the first name of the person who started performing at weddings, church choir and charity events?
