Based on this document, find evidence that explains why scientific progress about medicine, nature, and the universe was slow to come about during the middle ages?

Hello. You did not provide the document to which this question refers, which makes it impossible for your question to be answered accurately. However, based on some research, I can say that scientific progress on medicine, nature and the universe occurred slowly in the Middle Ages due to the dominance of creativity. That's because, the church dominated science, politics and economics in the Middle Ages and determined what could or could not be done or believed. Based on this, the church issued certain concepts about medicine, nature and the universe that should be accepted by everyone. Any scientific advance that showed that the concepts defended by the church were wrong, was quickly fought and exterminated.
