The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?

To answer this question, we must go back to the passage to see what it says about how corrective lenses aid the eye. The last sentence of the passage states that the corrective lenses "do the work that the eye can no longer do for itself." We need to find a similar relationship: something doing work that can no longer be done by something else. The correct answer describes such a relationship. The damaged strap can no longer fulfill its task; the duct tape bolsters the strap so it can do the task instead. The frayed strap cannot repair itself, so the situation is not temporary.
