Question: What was the rank of the man Hope served under in the Flanders Campaign? Passage 1:The East Lost Angeles freeway system and the East Los Angeles Interchange serve as an important center for the Los Angeles freeway network. It is also known for being the cause of displacing countless Mexican Angeleno communities, as 19 percent of East Los Angeles is intertwined with freeways. The freeway system grew as multiple freeways were built over two decades: the Santa Ana (5) Freeway (1944), the Hollywood (101) Freeway (1948), the San Bernardino (10) Freeway (1953), the Santa Monica (10) Freeway (extended to the East Los Angeles Interchange in 1961), the Long Beach (710) Freeway (1961), and the Pomona (60) Freeway (1965).Boyle Heights and neighboring communities protested against the first construction phases of the freeways. Community leaders rallied together to fight for their neighborhoods as they circulated petitions and organized public hearings. The construction of the freeways started as scheduled despite the resistance. The numerous freeways in this era displaced many East Los Angeles residents as they had their homes and property seized. Schools, churches, and community parks were also lost from construction. One notable structure lost in Boyle Heights was Saint Isabella Church and the Catholic elementary school. The loss of Hollenbeck Park was also a devastation to the community, since there was already a shortage of parks in the area. The Divide of Highways again justified the loss of communities by contending that residents would save time using the new freeways. Boyle Heights was a densely populated area because of low mortgages that were enjoyed by Mexican Angelo families. When families were forced to give up their homes they struggled to find homes that matched in affordability. Some families were also displaced in gang ridden areas and further from the freeways that they never used. The remaining residents in the area also still suffer the consequences of the construction of the surrounding freeways. Residents are now separated from parts of the community and face many effects of the area's air pollution caused by vehicles.
 Passage 2:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.
 Passage 3:Emmanuel was born on 2 March 1989 in Southend-on-Sea, a seaside resort town in Essex, England. Emmanuel is the second child of a half Dominican (Dominiquais) and half English mother, and a father of half-Saint Lucian and half English descent. Emmanuel demonstrated an affinity for the arts at an early age; she recalled that her mother first took notice of her passion and desire to become an actress during Emmanuel's attendance at the independent St Hilda's School (now closed) and later grammar Westcliff High School for Girls. In an interview with the New York Daily News, she commented, "When I was 3, [I'd] always cause drama that my mum decided maybe I should channel it properly—so she started me on acting, singing and dancing classes". At the age of 10, she played Young Nala in the West End production of the musical The Lion King.
