I want to know the answer to the following question:
In what century did antibiotics revolutionized medicine?
All the background I'm provided with is that "This has led to widespread problems with antimicrobial and antibiotic resistance, so much as to prompt the World Health Organization to classify antimicrobial resistance as a "serious threat [that] is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country".". Is that enough to answer the question?
Answer: no
