While asthma is a well recognized condition, there is not one universal agreed upon definition. It is defined by the Global Initiative for Asthma as "a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. The chronic inflammation is associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in the early morning. These episodes are usually associated with widespread but variable airflow obstruction within the lung that is often reversible either spontaneously or with treatment".
How do you stop the symptoms of cellular obstruction?
A: unanswerable

Digital-RGB LEDs are RGB LEDs that contain their own "smart" control electronics. In addition to power and ground, these provide connections for data-in, data-out, and sometimes a clock or strobe signal. These are connected in a daisy chain, with the data in of the first LED sourced by a microprocessor, which can control the brightness and color of each LED independently of the others. They are used where a combination of maximum control and minimum visible electronics are needed such as strings for Christmas and LED matrices. Some even have refresh rates in the kHz range, allowing for basic video applications.
 How are non-Digital-RGB LED strobe signals connected?
A: unanswerable

Penalties never result in a score for the offence. For example, a point-of-foul infraction committed by the defence in their end zone is not ruled a touchdown, but instead advances the ball to the one-yard line with an automatic first down. For a distance penalty, if the yardage is greater than half the distance to the goal line, then the ball is advanced half the distance to the goal line, though only up to the one-yard line (unlike American football, in Canadian football no scrimmage may start inside either one-yard line). If the original penalty yardage would have resulted in a first down or moving the ball past the goal line, a first down is awarded.

“The roots of all our modern academic fields can be found within the pages of literature.”  Literature in all its forms can be seen as written records, whether the literature itself be factual or fictional, it is still quite possible to decipher facts through things like characters’ actions and words or the authors’ style of writing and the intent behind the words. The plot is for more than just entertainment purposes; within it lies information about economics, psychology, science, religions, politics, cultures, and social depth. Studying and analyzing literature becomes very important in terms of learning about our history. Through the study of past literature we are able to learn about how society has evolved and about the societal norms during each of the different periods all throughout history. This can even help us to understand references made in more modern literature because authors often make references to Greek mythology and other old religious texts or historical moments. Not only is there literature written on each of the aforementioned topics themselves, and how they have evolved throughout history (like a book about the history of economics or a book about evolution and science, for example) but we can also learn about these things in fictional works. Authors often include historical moments in their works, like when Lord Byron talks about the Spanish and the French in ‘‘Childe Harold’s Pilgrimage: Canto I’’ and expresses his opinions through his character Childe Harold. Through literature we are able to continuously uncover new information about history. It is easy to see how all academic fields have roots in literature. Information became easier to pass down from generation to generation once we began to write it down. Eventually everything was written down, from things like home remedies and cures for illness, or how to build shelter to traditions and religious practices. From there people were able to study literature, improve on ideas, further our knowledge, and academic fields such as the medical field or trades could be started. In much the same way as the literature that we study today continue to be updated as we continue to evolve and learn more and more.
We can learn what by carefully examining our literature?
