Answer:
Language and religion are the cultural traits that have been influenced the most by European colonization.
Step-by-step explanation:
Latin America is a region that spreads from Mexico through Central America and South America. The majority of this region has been colonized by Spain, with Portugal having a big chunk in Brazil and several other colonizers but on a much smaller scale. Having the region under their control, the colonizers managed to have a big influence on the population, and some of the biggest influences can be seen in the language and religion of the region.
In all of the countries of the region, the most spoken language is Europen, mostly Spanish and Portuguese, with all other languages that are presently being used locally or on a much smaller scale. The religion in this region is the same throughout it, with Catholic Christianity being by far the most dominant religion, and it has been brought and forced upon the natives by the Spanish and Portuguese.
