Question: In 1873, one of the first papers in modern medicine on the subject tried to explain the pathophysiology of the disease while one in 1872, concluded that asthma can be cured by rubbing the chest with chloroform liniment. Medical treatment in 1880, included the use of intravenous doses of a drug called pilocarpin. In 1886, F.H. Bosworth theorized a connection between asthma and hay fever. Epinephrine was first referred to in the treatment of asthma in 1905. Oral corticosteroids began to be used for this condition in the 1950s while inhaled corticosteroids and selective short acting beta agonist came into wide use in the 1960s.
Is there an answer to this question: What two medications were widely used to treat asthma in 1905?

Answer: unanswerable


Question: 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.
Is there an answer to this question: What improved thanks to the Royal Air Force in 1933?

Answer: Navigation and weather forecasting


Question: Domestic dogs often display the remnants of countershading, a common natural camouflage pattern. A countershaded animal will have dark coloring on its upper surfaces and light coloring below, which reduces its general visibility. Thus, many breeds will have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.
Is there an answer to this question: A natural camo pattern is known as what?

Answer: countershading


Question: A broad operational definition is sometimes used to encompass the complexity of these diverse phenomena, where a gene is defined as a union of genomic sequences encoding a coherent set of potentially overlapping functional products. This definition categorizes genes by their functional products (proteins or RNA) rather than their specific DNA loci, with regulatory elements classified as gene-associated regions.
Is there an answer to this question: What does the typical definition of a gene categorize genes by?

Answer:
their specific DNA loci
