What practice of the catholic church that led martin luther to break with the church? why did he view this practice so negatively?

He did not like that the church used people for profit (made people pay for forgiveness and such) and that the church had so much power.

It could be anything, recent improvements in technology/telecommunication/internet have increased the pace of globalization.generally, it has something to do with technology. globalization means that people around the world are brought together through technology which speeds things up. so maybe some of those options could be correct. : )
