Chronic back pain is usually caused by a herniated or degenerated spinal disk. In most cases the disk will have been damaged years before chronic pain develops, and in fact an estimated one in five people over the age of 30 has a herniated or degenerated disk that shows no chronic symptoms. a deterioration of the abdominal and spinal muscles caused by insufficient exercise.

Answer choices

  1. Too Strong: will be sure / never0% picked this

    Four out of five people over the age of 30 can be sure they will never

    This is way, way too extreme. It's trying to play off the idea that 1/5 of people over 30 have a bad disk, but no chronic symptoms. That doesn't mean they never will. It means they currently don't.

  2. Too Strong: sure to be free5% picked this

    People who exercise their abdominal and spinal muscles regularly are sure to be free from

    Again, we have language that is comically extreme. We certainly wouldn't ever believe this claim in real life. No one is "sure to be free" from chronic back pain. Nothing in this paragraph would allow us to guarantee someone a pain-free rest of days.

  3. Out of Scope22% picked this

    Patients rarely suffer even mild and fleeting back pain at the time that a spinal disk first

    Out of Scope: mild / fleeting pain Too Strong: rarely We never discussed the idea of mild or fleeting pain. It's very possible that patients frequently experience mild pain when their disk first gets messed up. Nothing in this paragraph suggests otherwise. The passage was only talking about people who did or didn't have chronic pain (which means constantly recurring pain, the opposite of fleeting pain, which only lasts for a bit before disappearing).

  4. Out of Scope: doctors3% picked this

    Doctors can accurately predict which people who do not have chronic back pain will develop

    Nothing in this paragraph mentions doctors or allows us to derive what doctors can / can't do.

  5. Correct70% picked this

    There is a strategy that can be effective in delaying or preventing the onset of pain from a currently asymptomatic

    Why this is right

    This is lovably soft wording that reinforces the Causal Difference-Maker (don't exercise your core enough --c--> chronic pain later in life). We know there's a slice of people (1 out of 5 of people over 30) who currently have bad disks but don't currently have chronic pain. We hear that if they get it later in life, it'll be because of insufficient exercise. So getting 'sufficient exercise' would be a strategy that people with bad disks could currently try in order to hopefully avoid, or at least delay, when their bad disk turns into chronic pain.
