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.
Q: Passage: After being released from jail, Wallace made a demo tape called "Microphone Murderer", under the name Biggie Smalls, a reference to a character in the 1975 film Let's Do It Again as well as his stature; he stood at 6 feet 3 inches (1.91 m) and weighed 300 to 380 lb (140–170 kg) according to differing accounts. The tape was reportedly made with no serious intent of getting a recording deal. However, it was promoted by New York-based DJ Mister Cee, who had previously worked with Big Daddy Kane, and in 1992 it was heard by the editor of The Source.In March 1992, Wallace was featured in The Source's Unsigned Hype column, dedicated to aspiring rappers, and made a recording off the back of this success. The demo tape was heard by Uptown Records A&R and record producer Sean Combs, who arranged for a meeting with Wallace. He was signed to Uptown immediately and made an appearance on label mates Heavy D & the Boyz's "A Buncha Niggas" (from the album Blue Funk). Soon after Wallace signed his recording contract, Combs was fired from Uptown and started a new label, Bad Boy Records. Wallace followed and signed to the label in mid-1992.On August 8, 1993, Wallace's longtime girlfriend gave birth to his first child, T'yanna. Wallace had split with the girlfriend some time before T'yanna's birth. Despite having dropped out of high school himself, Wallace wanted his daughter to complete her education. He promised her "everything she wanted", saying that if his mother had promised him the same he would have graduated at the top of his class. He continued selling drugs after the birth to support his daughter financially. Once Combs discovered this, he forced Wallace to quit.Later in the year, Wallace, recording as the Notorious B.I.G., gained exposure after featuring on a remix to Mary J. Blige's single "Real Love". He recorded under this name for the remainder of his career, after finding the original moniker "Biggie Smalls" was already in use. "Real Love" peaked at No. 7 on the Billboard Hot 100 chart and was followed by a remix of Blige's "What's the 411?". He continued this success, to a lesser extent, on remixes with Neneh Cherry ("Buddy X") and reggae artist Super Cat ("Dolly My Baby", also featuring Combs) in 1993. In April 1993, his solo track, "Party and Bullshit", appeared on the Who's the Man? soundtrack. In July 1994, he appeared alongside LL Cool J and Busta Rhymes on a remix to label mate Craig Mack's "Flava in Ya Ear", which reached No. 9 on the Billboard Hot 100.
