Even as learning expanded, science made only small progress in Europe the Middle Ages because  monks controlled the printing of books, thereby limiting the progress of science as it was contrary to their religion.

Explanation:

Until Gutenberg's invention of the printing press in 1459, books were created manually and by artisans by Catholic monks, who only created books and writings related to religion, or had content that included God or spirituality as a central or important theme.

For this reason, given that science in many cases posed an absolute contradiction to religious ideas, the monks arbitrarily decided not to publish these books, with which despite the progress of science and knowledge, they did not reach the majority of the population.

500 books can be produced by one man and a printing press within 5 months, while a copyist can only produce one in the same amount of time

the articles of confederation only set up the continental congress at the federal level. there were no executive or judicial branches except within the states. the states were allowed to keep every right that was not specifically given to congress. the bonding of the states was through a 'firm league of friendship' that best served as a defense agreement against invasion. states were not allowed to use taxes as a way to discourage treaties, and states were extremely limited in their dealings with foreign nations.

not many historians today talk about the strengths of the articles of confederation, likely because of how unpopular the document quickly became. the articles did set the legislative body, congress, as the highest power in the nation because of the fear of monarchy. congress had the sole power to declare war, assign treaties, entertain foreign relations, and operate post offices. disputes between states and territorial issues were to be brought to congress. the document also stipulated that canada was allowed to enter the union if they desired.

there were more weaknesses than strengths under the articles of confederation. the lack of power given to the continental congress strangled the federal government. the articles gave congress the power to pass laws but no power to enforce those laws. if a state did not support a federal law, that state could simply ignore it. congress had no power to levy taxes or regulate trade. without a federal court system or executive leader, there would be no way to enforce these laws, either. amending the articles of confederation would also require a unanimous decision, which would be extremely difficult.
