I want to know the answer to the following question:
How much did the mortality rate of common bacterial infections decline between 1946-1955?
All the background I'm provided with is that "The study further examined mortality rates for eight common diseases for which antibiotics offered effective therapy (syphilis, tuberculosis, dysentery, scarlet fever, whooping cough, meningococcal infections, and pneumonia), and found a 56% decline over the same period.". Is that enough to answer the question?
Answer: yes
