I want to know the answer to the following question:
About how much had the death rate from TB been reduced in Europe by the midpoint of the 20th century?
All the background I'm provided with is that "In Europe, rates of tuberculosis began to rise in the early 1600s to a peak level in the 1800s, when it caused nearly 25% of all deaths.". Is that enough to answer the question?
Answer: no
