I think that it’s b because it’s kinda like what goes along with the question and what makes sense the most!!!!!
From 1841-1850, 1.3 million people moved overseas, the greatest part around 70% went to the USA, the rest of them shipped to Australia and only 2% to Canada. A lot of people died because of different diseases during the trip and the conditions were terrible. In the USA, quarantine centers were established for arriving ships, where sick emigrants recovered. The emigration continued until the First World War. Canada and Australia reacted in a different way, because the amount of emigrants was much lower, the greatest part of emigrants decided to move to the USA. Emigrants had the poorest jobs and bad conditions for life in the USA.
The maps made in ancient times weren’t accurate because they didn’t have the technology or tools we have today.
