Background: Born in Scotland on 15 June 1792, he was son of John Mitchell of Carron Works and was brought up from childhood by his uncle, Thomas Livingstone of Parkhall, Stirlingshire. On the death of his uncle, he joined the British army in Portugal as a volunteer, at the age of sixteen. On 24 June 1811, at the age of nineteen, he received his first commission as 2nd Lieutenant in the 1st Battalion 95th Rifles (later the Rifle Brigade / Royal Green Jackets). Utilising his skills as a draughtsman of outstanding ability, he was occasionally employed in the Quartermaster-General's department under Sir George Murray.
Context: Mitchell's fourth expedition was into Queensland in 1845-46. He was convinced that a significant river must flow north-west into the Gulf of Carpentaria, this being the main thrust of the endeavour.  On 15 December 1845 Mitchell started from Boree (Buree in Mitchell's journal) with a large party including Edmund Kennedy as second in command (later speared to death at Escape River near Cape York). He struck the Darling River above Fort Bourke then continued to the Narran River, the Balonne, and the Culgoa. On 12 April 1846 he came to a natural bridge of rocks on the main branch of the Balonne which he called St.George Bridge, now the site of the town of St George. Kennedy was left in charge of the main body here, and was instructed to follow on slowly while Mitchell pushed ahead with a few men. Mitchell followed the Balonne to the Maranoa, and the Cogoon (now called Muckadilla Creek, near Roma). This rivulet led him to a magnificent pastoral district in the midst of which stood a solitary hill that he named Mount Abundance. He then crossed a low watershed to the Maranoa and awaited Kennedy's arrival. Kennedy rejoined Mitchell on 1 June 1846.  Leaving Kennedy for a second time, he set out on an extensive excursion of more than four months. Mitchell traversed the country at the head of the Maranoa and discovered the Warrago River. Keeping north over the watershed, he traversed the Claude and Nogoa rivers, then reached the Belyando River, an upper reach of the Burdekin River. This had already been discovered by Ludwig Leichhardt on his expedition to Port Essington on 2 April 1845. Intensely mortified to find that he was on a tributary of the Burdekin River, and approaching the ground already trodden by Leichhardt, he returned to the head of the Nogoa and struck west, after dividing his party and forming a stationary camp. He continued west, making a new discovery which he was certain was the fabled north-west river. In honour of the sovereign of the time he decided to call it Victoria River. Having run out of time, he turned back towards the main party. It was here that Mitchell first noticed the well known grass that bears his name. On the homeward journey he trekked along the Maranoa River to St.George Bridge, arriving in Sydney 20 January 1847. Later that year, Kennedy proved beyond doubt that the Victoria did not continue north-west, but turned south-west and joined Cooper Creek. He renamed the watercourse the Barcoo River from a name mentioned by local Aborigines.
Question: Was he correct?
Answer: Later that year, Kennedy proved beyond doubt that the Victoria did not continue north-west, but turned south-west and joined Cooper Creek.

Problem: Background: Fugazi (; foo-GAH-zee) is an American punk rock band that formed in Washington, D.C. in 1987. The band consists of guitarists and vocalists Ian MacKaye and Guy Picciotto, bassist Joe Lally and drummer Brendan Canty. Fugazi are noted for their unique sound, blending of elements of dub/reggae with high energy rock and punk/hardcore-styled guitars, as well as for their business practices and contempt towards the music industry. The band, and others from the punk and hardcore scene leading up to the early 1990s, were among the early adopters of what grew to be known as the DIY ethic.
Context: After the hardcore punk group Minor Threat dissolved, Ian MacKaye (vocals and guitar) was active with a few short-lived groups, most notably Embrace. MacKaye decided he wanted a project that was "like The Stooges with reggae", but was wary about forming another band after Embrace's break up. MacKaye recalled, "My interests were not necessarily to be in a band, but to be with people who wanted to play music with me."  MacKaye recruited ex-Dag Nasty drummer Colin Sears and bass guitarist Joe Lally, and the trio began practicing together in September 1986. After a few months of rehearsals, Sears returned to Dag Nasty and was replaced by Brendan Canty (earlier of Rites of Spring). One day Canty's Rites of Spring bandmate Guy Picciotto dropped by during a practice session to see how his friend was getting along; he later admitted he secretly harbored the idea of joining the group. But Picciotto was disappointed that there seemed to be no place for him.  After some uncertainty from Canty about what he wanted to do with his future, the trio regrouped and booked their first show at the Wilson Center in early September 1987. The group still needed a name, so MacKaye chose the word "fugazi" from Mark Baker's Nam, a compilation of stories of Vietnam War veterans, it there being a slang acronym for "Fucked Up, Got Ambushed, Zipped In [into a body bag]".  The band began inviting Picciotto to practices. Inspired by use of a foil in hip hop, Picciotto sang backup vocals. After his band Happy Go Licky broke up, he became more involved with Fugazi. MacKaye eventually asked Picciotto to become a full member, which he accepted.
Question: what were some of their early songs?
