The problem: Answer a question about this article:
Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption. There is little to no structural damage. The most common cause of this type of diarrhea is a cholera toxin that stimulates the secretion of anions, especially chloride ions. Therefore, to maintain a charge balance in the lumen, sodium is carried with it, along with water. In this type of diarrhea intestinal fluid secretion is isotonic with plasma even during fasting. It continues even when there is no oral food intake.
What is secretory diarrhea?
****
The answer: an increase in the active secretion, or there is an inhibition of absorption

After several failed attempts, in 1930 the first aeroplane reached Bermuda. A Stinson Detroiter seaplane flying from New York, it had to land twice in the ocean: once because of darkness and again to refuel. Navigation and weather forecasting improved in 1933 when the Royal Air Force (then responsible for providing equipment and personnel for the Royal Navy's Fleet Air Arm) established a station at the Royal Naval Dockyard to repair (and supply replacement) float planes for the fleet. In 1936 Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation to New York City.
Who began experimenting with flights from Berlin to New York, stopping in the azores?
****
The answer: Luft Hansa

Microbiological culture is a principal tool used to diagnose infectious disease. In a microbial culture, a growth medium is provided for a specific agent. A sample taken from potentially diseased tissue or fluid is then tested for the presence of an infectious agent able to grow within that medium. Most pathogenic bacteria are easily grown on nutrient agar, a form of solid medium that supplies carbohydrates and proteins necessary for growth of a bacterium, along with copious amounts of water. A single bacterium will grow into a visible mound on the surface of the plate called a colony, which may be separated from other colonies or melded together into a "lawn". The size, color, shape and form of a colony is characteristic of the bacterial species, its specific genetic makeup (its strain), and the environment that supports its growth. Other ingredients are often added to the plate to aid in identification. Plates may contain substances that permit the growth of some bacteria and not others, or that change color in response to certain bacteria and not others. Bacteriological plates such as these are commonly used in the clinical identification of infectious bacterium. Microbial culture may also be used in the identification of viruses: the medium in this case being cells grown in culture that the virus can infect, and then alter or kill. In the case of viral identification, a region of dead cells results from viral growth, and is called a "plaque". Eukaryotic parasites may also be grown in culture as a means of identifying a particular agent.
What type of culture is a principal tool used to diagnose infectious disease?
