1. chronic bronchitis is characterized by spasm and narrowing of the bronchioles due to exposure to allergens.
2. with pneumothorax, the lung collapses because the negative pressure in the pleural space is lost.
3. anaphylactic reactions occur only in patients with a previous history of asthma or allergies.
4. decreased breath sounds in asthma occur because fluid in the pleural space has moved the lung away from the chest wall.

Explanation:

1. Chronic bronchitis is characterized by long - term inflammation of the bronchi, not by spasm and narrowing due to allergens (which is more typical of asthma). So it's false.
2. In pneumothorax, air enters the pleural space, causing the loss of negative pressure and lung collapse. This is true.
3. Anaphylactic reactions can occur in anyone, not just those with a history of asthma or allergies. So it's false.
4. Decreased breath sounds in asthma are due to airway obstruction, not fluid in the pleural space moving the lung away from the chest wall. So it's false.
