A) The study doesn't say that 1 out of 5 people has back pain, it says that 1 out of 5 people OVER 30 HAVE A SPECIFIC CONDITION THAT SHOWS NO CHRONIC SYMPTOMS. Way off.
B) The pain stems from lack of exercise in general, but that doesn't mean that lack of exercise is the only source of back pain.
C) This makes a claim about acute pain, but the reading only mentions chronic pain.
D) This one seems close, but there are plenty of things doctors don't know about your future that could lead to back pain, and even if they did (e.g., if they knew you weren't going to exercise), the reading states that the correlation between back pain and exercise is only a general correlation, not a strict one.
E) Note that this doesn't say the strategy WILL 100% OF THE TIME be effective; it says that it can be effective. Keeping in mind the general correlation mentioned above, we can see that this strategy would be to exercise.
