Answer:
Surfactant increases airflow. It has this effect on airflow because it reduces resistance to lung inflation. Airflow increased as predicted.
Explanation:
Pulmonary surfactant is a complex mixture of lipids and proteins secreted by the Type II alveolar cells. The major component of surfactant, dipalmitoyl-phosphatidylcholine (DPPC), is an amphiphatic phospholipid. The main function of the pulmonary surfactant is to reduce the surface tension at the air/liquid interface in the lungs by forming lining layer between the aqueous airway liquid and the inspired air. prevents alveolar and airway collapse at end-expiration and thus allows cyclic ventilation of the lungs. It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. By lowering alveolar surface tension, pulmonary surfactant provides two important benefits:
(1) it increases pulmonary compliance, reducing the work of inflating the lungs; and
(2) it reduces the lungs’ tendency to recoil, so they do not collapse as readily.

To protect Venice (a city in Italy) from over-tourism, the number of tourists allowed should be 55,000 per day.
Venice is a beautiful city in Italy that attracts a great deal of tourists. Some 20 million people flood Venice every year. on its busiest days, the tourist number increases to 120,000 which is almost double the population residing there.
Venice is in the mood to reduce tourist entry due to the fact that many people come on cruises, stay for a few hours, and leave, providing no economic benefit.
The visitors who do stay for a night or two may also contribute to Venice's problems. Due to high property prices, owners are converting family homes and low-income rentals into lucrative holiday rentals. As a result, housing is becoming increasingly expensive, and only the very wealthy can afford to live here.
The very well solution is that the tourist count should be limited to just as the population count who are the permanent residents i.e. 55,000.

This means that, for example if a group or two people are having an argument it’s best that it doesn’t in with one side of the argument winning, or feeling as if they’re more correct than the others. It’s best that both people or peoples feel like they’ve won in the argument, this way it wouldn’t involve any long term conflict.. which could lead to something very unnecessary or sometimes even harmful to both people.
Since they realize there is a tsunami there have an emergency plan, emergency equipment and might have escaped.
