The conclusion that the writer should add to summarize the argument of the passage is: "Hence, more schools should follow the trend of starting later in the morning if they want to see improved test scores, greater attendance numbers, and, most importantly, healthier, happier teens."

(B) Skeletal muscle contractions and variations in thoracic pressure brought on by respiratory activity are crucial for lymph and venous blood flow.
<h3>
What is respiratory movement?</h3>
Mammals use the diaphragm muscle and the intercostal muscles between the ribs to breathe.
These muscles contract, causing the diaphragm to descend and the ribs to rise, which causes the lungs to expand and the air to be pulled in (see inspiration).
The converse happens when you relax; you force air out of your lungs as you exhale.
Lymph and venous blood flow depend on skeletal muscle contractions and changes in thoracic pressure brought on by respiratory exercise.
So, in healthy individuals, the chest wall and abdomen move in unison to move inward during inspiration and outward during expiration.
Changes in this pattern will enable the diagnosis of altering contributions from the respiratory muscles to the tidal breath.
Therefore, (B) skeletal muscle contractions and variations in thoracic pressure brought on by respiratory activity are crucial for lymph and venous blood flow.
