Answer:
Asthma is: A condition in which a person's airways become inflamed, narrow and swell, and produce extra mucus, which makes it difficult to breathe.
Asthma can be minor or it can interfere with daily activities. In some cases, it may lead to a life-threatening attack.
Asthma may cause difficulty breathing, chest pain, cough, and wheezing. The symptoms may sometimes flare-up.
Asthma can usually be managed with rescue inhalers to treat symptoms and controller inhalers that prevent symptoms. Severe cases may require longer-acting inhalers that keep the airways open, as well as oral steroids.

America´s literary heritage
Explanation:
From the Colonial Period (17th century) and Early National Period to the Romantic Period (1830- 1870) to Realism and Naturalism (1870-1910) to the Modernist Period (1910-1945), they all contributed in some way or another to the Contemporary Period in literature, that reflected the social upheaval that acompanied the contemporary and all the other socio-political periods of America.
There is no such thing as a typical American writing style.
The core values (like the natural rights of people) do play a significant role but they don´t determine American literature.
America´s leadership or hegemony is a fact but it doesn´t make its literature consistent.
The electromagnetic wave is self propagating, what I mean by that is, an electric field generates a magnetic field at 90 degree phase angle, and the magnetic wave you get as a result generates the electric wave at the same phase angle. The interchange of electric to magnetic and vice versa continues and lets the electromagnetic waves to travel without any medium. Quite interesting, really!
