Problem: Background: Sean John Combs was born on November 4, 1969 in Manhattan's Harlem neighborhood in New York City, and was raised in Mount Vernon, New York. His mother, Janice (Smalls), was a model and teacher's assistant, and his father, Melvin Earl Combs, served in the U.S. Air Force and was an associate of convicted New York drug dealer Frank Lucas. At age 33, Melvin was shot to death while sitting in his car on Central Park West, when Combs was 2 years old. Combs graduated from the Roman Catholic Mount Saint Michael Academy in 1987.
Context: In 1998, Combs started a clothing line, Sean John. It was nominated for the Council of Fashion Designers of America (CFDA) award for Menswear Designer of the Year in 2000, and won in 2004. California billionaire Ronald Burkle invested $100 million into the company in 2003.  Also in 2003, the National Labor Committee revealed that factories producing the clothing in Honduras were violating Honduran labor laws. Among the accusations were that workers were subjected to body searches and involuntary pregnancy tests. Bathrooms were locked and access tightly controlled. Employees were forced to work overtime and were paid sweatshop wages. Charles Kernaghan of the National Labor Committee told The New York Times that "Sean Puff Daddy obviously has a lot of clout, he can literally do a lot overnight to help these workers."  Combs responded with an extensive investigation, telling reporters "I'm as pro-worker as they get". On February 14, 2004, Kernaghan announced that improvements had been implemented at the factory, including adding air conditioning and water purification systems, firing the most abusive supervisors, and allowing the formation of a labor union. In late 2006, the department store Macy's removed Sean John jackets from their shelves when they discovered that the clothing was made using raccoon dog fur. Combs had not known the jackets were made with dog fur, but as soon as he was alerted, he had production stopped.  In November 2008, Combs added a men's perfume called "I Am King" to the Sean John brand. The fragrance, dedicated to Barack Obama, Muhammad Ali, and Martin Luther King, featured model Bar Refaeli in its advertisements. In early 2016, Sean John introduced the brand's GIRLS collection.
Question: What happened after this?
Answer: Combs responded with an extensive investigation, telling reporters "I'm as pro-worker as they get".

Problem: Background: The Tlingit language (English: , ; Tlingit: Lingit [linkit]) is spoken by the Tlingit people of Southeast Alaska and Western Canada. It is a branch of the Na-Dene language family. Extensive effort is being put into revitalization programs in Southeast Alaska to revive and preserve the Tlingit language and culture. Missionaries of the Russian Orthodox Church were the first to develop a written version of Tlingit, using the Cyrillic script to record and translate it, when the Russian Empire had contact with Alaska and the coast of North America down to Sonoma County, California.
Context: Tlingit has eight vowels, four vowels further distinguished formally by length. However, the length distinction is often in terms of tenseness rather than length, particularly in rapid speech. For the Northern dialect, the dominant spoken dialect of Tlingit and the standard for written Tlingit, every vowel may take either high or low tone; in the orthography high tone is indicated by an acute accent, e.g. aa, and low tone is unmarked, e.g. aa. The Southern and Transitional dialects have a mid tone which is unmarked and additional low tone which is marked by a grave accent, e.g. aa.  As noted in the vowel chart above, there is an allophone of /a:/ (orthographic aa) which is realized as [a:] under the influence of uvular consonants, however this is not consistent for all speakers. The backness influence arises from articulation with uvular consonants, thus the word khaa "person" is often spoken as [qha:], whereas the word (a) kaa "on (its) surface" is said as [(?^) kha:] by the same speakers.  Word onset is always consonantal in Tlingit, i.e. no word may begin with a vowel. Where one would occur theoretically by e.g. prefixing or compounding, the vowel is obligatorily preceded by either [?] or [j]. The former is universal in single words, and the latter is found varying with [?] in word-medial position in compounds. The orthography does not reflect the [?] in word-initial position, but either . or y may be seen in medial position. For example, the word khoowat'aa "the weather is hot" (khu-yu-ya-t'aa, INDH.OBJ-PERF-(0, -D, +I)-hot) is phonetically [qhu:w^t'a:], but when the perfective prefix yu- is word initial in uwat'aa "it is hot" (0-yu-ya-t'aa, 3NEU.OBJ-PERF-(0, -D, +I)-hot) the phonetic form is [?Uw^t'a:] where the glottal stop appears to ensure that the word begins with a consonant.
Question: and what is low tone indicated by?
Answer: low tone is unmarked,

Problem: Background: Roger Keith "Syd" Barrett (6 January 1946 - 7 July 2006) was an English singer, songwriter, musician, composer, and painter. Best known as a founder member of the band Pink Floyd, Barrett was the lead singer, guitarist and principal songwriter in its early years and is credited with naming the band. Barrett was excluded from Pink Floyd in April 1968 after David Gilmour took over as their new guitarist, and was briefly hospitalised amid speculation of mental illness. Barrett was musically active for less than ten years.
Context: The second album, Barrett, was recorded more sporadically than the first, with sessions taking place between February and July 1970. The album was produced by David Gilmour, and featured Gilmour on bass guitar, Richard Wright on keyboard and Humble Pie drummer Jerry Shirley. The first two songs attempted were for Barrett to play and/or sing to an existing backing track. However, Gilmour thought they were losing the "Barrett-ness". One track ("Rats") was originally recorded with Barrett on his own. That would later be overdubbed by musicians, despite the changing tempos. Shirley said of Barrett's playing: "He would never play the same tune twice. Sometimes Syd couldn't play anything that made sense; other times what he'd play was absolute magic." At times Barrett, who experienced synaesthesia, would say: "Perhaps we could make the middle darker and maybe the end a bit middle afternoonish. At the moment it's too windy and icy".  These sessions were happening while Pink Floyd had just begun to work on Atom Heart Mother. On various occasions, Barrett went to "spy" on the band as they recorded their album.  Wright said of the Barrett sessions:  Doing Syd's record was interesting, but extremely difficult. Dave [Gilmour] and Roger did the first one (The Madcap Laughs) and Dave and myself did the second one. But by then it was just trying to help Syd any way we could, rather than worrying about getting the best guitar sound. You could forget about that! It was just going into the studio and trying to get him to sing.
Question: how was barrett received?
Answer:
Shirley said of Barrett's playing: "He would never play the same tune twice.
