Here is a question about this article: Breathing is largely driven by the muscular diaphragm, which divides the thorax from the abdominal cavity, forming a dome with its convexity towards the thorax. Contraction of the diaphragm flattens the dome, increasing the volume of the cavity in which the lung is enclosed. Air enters through the oral and nasal cavities; it flows through the larynx, trachea and bronchi and expands the alveoli. Relaxation of the diaphragm has the opposite effect, passively recoiling during normal breathing. During exercise, the abdominal wall contracts, increasing visceral pressure on the diaphragm, thus forcing the air out more quickly and forcefully. The rib cage itself also is able to expand and contract the thoracic cavity to some degree, through the action of other respiratory and accessory respiratory muscles. As a result, air is sucked into or expelled out of the lungs, always moving down its pressure gradient. This type of lung is known as a bellows lung as it resembles a blacksmith's bellows. Mammals take oxygen into their lungs, and discard carbon dioxide.
What is the answer to this question: When air enters both the oral and nasal cavities, where does it flow through?
****
So... larynx, trachea and bronchi


Here is a question about this article: Arnold, Constable was the first American department store. It was founded in 1825 by Aaron Arnold (1794?-1876), an emigrant from Great Britain, as a small dry goods store on Pine Street in New York City. In 1857 the store moved into a five-story white marble dry goods palace known as the Marble House. During the Civil War Arnold, Constable was one of the first stores to issue charge bills of credit to its customers each month instead of on a bi-annual basis. Recognized as an emporium for high-quality fashions, the store soon outgrew the Marble House and erected a cast-iron building on Broadway and Nineteenth Street in 1869; this “Palace of Trade” expanded over the years until it was necessary to move into a larger space in 1914. In 1925, Arnold, Constable merged with Stewart & Company and expanded into the suburbs, first with a 1937 store in New Rochelle, New York and later in Hempstead and Manhasset on Long Island, and in New Jersey. Financial problems led to bankruptcy in 1975.
What is the answer to this question: When was the "Palace of Trade" built? 
****
So... 1869


Here is a question about this article: Before the 20th century, the term matter included ordinary matter composed of atoms and excluded other energy phenomena such as light or sound. This concept of matter may be generalized from atoms to include any objects having mass even when at rest, but this is ill-defined because an object's mass can arise from its (possibly massless) constituents' motion and interaction energies. Thus, matter does not have a universal definition, nor is it a fundamental concept in physics today. Matter is also used loosely as a general term for the substance that makes up all observable physical objects.
What is the answer to this question: What term is used to describe the type of definition that matter would have if all scientists could agree on its definition?
****
So...
universal
