Recent meta-analyses indicate that mindfulness-based therapies reduce symptoms of generalized anxiety. The reductions, however, are most pronounced in trials with active control groups and shorter follow-up windows. As trial length and methodological rigor increase, the size of the apparent benefit consistently shrinks.
Which choice best describes the function of the second and third sentences in the text?
- A
They introduce a different therapeutic approach.
- B
They flatly refute the meta-analyses' main finding.
- C
They restate the headline result in different language.
- Dcheck_circle
They identify methodological conditions under which the apparent benefit diminishes, qualifying the headline result.
Explanation
The two sentences narrow the headline by tying the size of the effect to specific trial conditions. B captures this qualifying function.
