What continent did Pedro Cabral first visit in 1500, known for the Amazon river and Mt. Aconcagua?

Pedro Cabral is known for his discovery of the land that is now Brazil when he made landfall in 1500. This event marks the beginning of Portuguese expansion into what would become a significant territory in South America. The Amazon River, one of the most famous rivers in the world, flows through Brazil, showcasing the continent's rich natural resources and biodiversity. Moreover, Mt. Aconcagua, while actually located in the Andes mountain range within Argentina, is often associated with the continent's geographical features.

The other options refer to different continents that do not relate to Cabral's exploration. Africa, Asia, and Europe do not have the same historical connection to his voyage and do not feature the Amazon River or Mt. Aconcagua prominently as South America does. Therefore, identifying South America emerges as the correct understanding of the continent linked with Cabral's first visit.
