Question: What country sent the most legal immigrants to the city where Gotham is filmed from the region serving as the middle leg of the journey from England to the continent with an AIDS pandemic to the Americas?

AIDS is currently a pandemic, with infection rates as high as 25% in southern and eastern Africa. In 2006, the HIV prevalence rate among pregnant women in South Africa was 29.1%. Effective education about safer sexual practices and bloodborne infection precautions training have helped to slow down infection rates in several African countries sponsoring national education programs. Infection rates are rising again in Asia and the Americas. HIV originated in Africa, and spread to the United States via Haiti between 1966 and 1972. The AIDS death toll in Africa may reach 90–100 million by 2025. <SEP> Ecuador, Colombia, Guyana, Peru, and Brazil were the top source countries from South America for legal immigrants to the New York City region in 2013; the Dominican Republic, Jamaica, Haiti, and Trinidad and Tobago in the Caribbean; Egypt, Ghana, and Nigeria from Africa; and El Salvador, Honduras, and Guatemala in Central America. Amidst a resurgence of Puerto Rican migration to New York City, this population had increased to approximately 1.3 million in the metropolitan area as of 2013. <SEP> ``show me the way to go home ''is a popular song written in 1925 by the pseudonymous`` irving king'' (the english songwriting team james campbell and reginald connelly). the song is said to have been written on a train journey from london by campbell and connelly. they were tired from the traveling and had a few alcoholic drinks during the journey, hence the lyrics. the song is in common use in england, ireland, scotland, wales and north america. <SEP> Historically the particular routes were also shaped by the powerful influence of winds and currents during the age of sail. Returning from North America, it is easiest to follow the Gulf Stream in a northeasterly direction using the westerlies. For example, from the main trading nations of Western Europe it was much easier to sail westwards after first going south of 30 N latitude and reaching the so - called ``trade winds ''; thus arriving in the Caribbean rather than going straight west to the North American mainland. A similar triangle to this, called the volta do mar was already being used by the Portuguese, before Christopher Columbus' voyage, to sail to the Canary Islands and the Azores. Columbus simply expanded the triangle outwards, and his route became the main way for Europeans to reach, and return from, the Americas. <SEP> argentina: the torch relay leg in buenos aires, argentina, held on april 11, began with an artistic show at the lola mora amphitheatre in costanera sur. in the end of the show the mayor of buenos aires mauricio macri gave the torch to the first torchbearer, carlos espínola. the leg finished at the buenos aires riding club in the palermo district, the last torchbearer being gabriela sabatini. the 13.8 km route included landmarks like the obelisk and plaza de mayo. the day was marked by several pro-tibet protests, which included a giant banner reading "free tibet", and an alternative "human rights torch" that was lit by protesters and paraded along the route the flame was to take. most of these protests were peaceful in nature, and the torch was not impeded. chinese immigrants also turned out in support of the games, but only minor scuffles were reported between both groups. runners surrounded by rows of security carried the olympic flame past thousands of jubilant argentines in the most trouble-free torch relay in nearly a week. people showered the parade route with confetti as banks, government offices and businesses took an impromptu half-day holiday for the only latin american stop on the flame's five-continent journey. <SEP> Filming for the first season finished on March 24, 2015. In February 2014, it was reported that production would begin in New York City in March.
