Question
1. Scientists used to think vagal tone was largely stable, like your height in adulthood.
A.To appreciate why this matters, here’s a quick anatomy lesson.
B.Subtle variations in your heart rate reveal the strength of this brain-heart connection, and as such, heart-rate variability provides an index of your vagal tone.
C.Your brain is tied to your heart by your vagus nerve.
D.Our data show that this part of you is plastic, too, and altered by your social habits.
6. By and large, the higher your vagal tone the better.

Solution
The correct option is D DACB
1D is a mandatory pair as both show a contrast. CB is also a mandatory pair as B explains the brain heart connection mentioned in C. AC is also a mandatory pair as C explains the anatomy lesson talked about in A. So option (4) is the answer.
