The correct answer to this open question is the following.
You did not include the text so we can read it. However, we can help to comment on the following.
What a section like that could explain that other sections do not is that history is written by the victorious, but it is one side of the stry. You always need to know the other side if you really want to know the truth.
In this case, as we could not read the text because you did not attach it, we can say that Christopher Columbus did somethings that are questionable, and others were wrong, but that doesn't appear in textbooks. Only the side says he discovered the American on October 12, 1492.
But if you do some research and dig over other versions and documents, you can find that he did not treat Native Indians well, he was not the first to really get to the Americas, that Indians tried to defend themselves against the mistreatments of Columbus crew, and yes, today there are many people and groups that demand to replace Columbus Day with Indigenous Peoples Day, as a way to honor Native American Indian tribes.
