Input: Question: When was the periodical that Brandenburg became  a contract photographer for in 1978 first published? Passage 1:Jim Brandenburg was born and raised in Luverne, Minnesota in the farms and prairies of Southwestern Minnesota, USA. After studying at Worthington Community College, he went on to attend the University of Minnesota Duluth, where he majored in art history and worked for the local public television station. Upon graduating, he returned to Worthington, Minnesota and began working as a photojournalist for the Worthington Daily Globe. Within months, he began submitting work to the National Geographic Society as a freelance photographer, and in 1978 he became a contract photographer for National Geographic Magazine. Additionally, his photography has been published in a number of National Geographic Society books including "Journey Into China", "Heart of a Nation" and "Discovering Britain and Ireland", in which his photos of the Highlands in Scotland were featured.
 Passage 2:The opening phase of what came to be called the Burnside Expedition, the Battle of Roanoke Island was an amphibious operation of the American Civil War, fought on February 7–8, 1862, in the North Carolina Sounds a short distance south of the Virginia border. The attacking force consisted of a flotilla of gunboats of the Union Navy drawn from the North Atlantic Blockading Squadron, commanded by Flag Officer Louis M. Goldsborough, a separate group of gunboats under Union Army control, and an army division led by Brig. Gen. Ambrose Burnside. The defenders were a group of gunboats from the Confederate States Navy, termed the Mosquito Fleet, under Capt. William F. Lynch, and about 2,000 Confederate soldiers commanded locally by Brig. Gen. Henry A. Wise. The defense was augmented by four forts facing on the water approaches to Roanoke Island, and two outlying batteries. At the time of the battle, Wise was hospitalized, so leadership fell to his second in command, Col. Henry M. Shaw.
 Passage 3:Until the middle of the nineteenth century, the area was occupied by farms and orchards which belonged to the residents of Baku. After the construction of the Baku Train Station in 1883, there arose a need in a paved road that would connect the station with the city. In 1887, the first telephone exchange in Baku was built here. It gave the street its first name, Telefonnaya (Telephone Street). By the end of the nineteenth century, horsecars already ran on the street. The street itself, however, continued to be regarded as a city periphery, home to the urban poor and beggars, well into the end of the nineteenth century. In 1898, it gained importance due to the construction of the first Lutheran church in Baku. In the early twentieth century, oil magnate Musa Naghiyev had the city's first multi-family residentials built on this street. In 1913, Telefonnaya was renamed to Romanovsky Prospekt (Romanov Avenue) to mark the 300th anniversary of the Romanov rule in the Russian Empire. In 1918, after Azerbaijan became independent from Russia, it was renamed to Lindley Street after Sir William Lindley who had contributed to the infrastructural development of Czar-era Baku. In 1923, after the Bolshevik power was installed in Azerbaijan, the Soviet government decided to get rid of the "bourgeois toponymy" and the street was given the name 28 April (the date of Azerbaijan's sovietisation in 1920). It was gradually built up as one or two-storey courtyard-based buildings gave way to blocks of flats, or were transformed into taller buildings through superstructures. In 1934, two massive identical Stalinist-style buildings were completed at the very beginning of the street, designed by Mikayil Huseynov and Sadikh Dadashov. One of them housed the Nizami Cinema, while the other later became the head office of AzerTaj. In the 1950s, the so-called Soldier Market was removed from the former Yarmarochnaya Square to be replaced by the Samad Vurghun Park, featuring the poet's giant statue at the entrance. In 1967, the underground of the street was traversed by the first metro line, with 28 April station built nearby. In 1991, both the street and the station were renamed to 28 May to mark the anniversary of Azerbaijan's declaration of independence in 1918. Today 28 May Street is one of the largest in the city. The traffic between Bulbul Avenue and Sorge Street is one-way from east to west. The tramway which connected the easternmost part of the street with the Black City was dismantled in the early 2000s.
