Amaya is writing an argumentative essay on how the Columbian Exchange expanded the European economy. Which source would most likely provide relevant evidence? an article in the Journal of European History from 2019
an article from www. europeanhistory. net that was updated in 2008
a blog from a carmaker on European Economy that was updated recently

the second one, aan article from www.europeanhistory.net that was updated in 2008.

Explanation:

This source isn't very recent (but it doesnt need to be because Amaya is writing about the history of Europe), but we do know that it was updated, which implies that more relevent information was posted. The information is coming from a trustworthy source (we know this because of the url the article is from), so is likely very relevent and relaible. The last source is irrelevent becasue it's abput a carmaker who had/has nothing to do with the Columbian Exchange, and the first source is from a journal (we don't know who the journal belongs to, or what kind of information is in it).

crop rotation kepy different plants in the soil instead of once constintly. when switching out plants you have different nutrients being absorbed at different speeds and different roots growing differently therfore the spoil and water flow have to adapt and carry fresh nutrients to carry the constant changes that were going on in the soil.

i thinl it is the 1st answer
