Problem: Military history of the United States:

The SpanishAmerican War was a short decisive war marked by quick, overwhelming American victories at sea and on land against Spain. The Navy was well-prepared and won laurels, even as politicians tried (and failed) to have it redeployed to defend East Coast cities against potential threats from the feeble Spanish fleet. The Army performed well in combat in Cuba. However, it was too oriented to small posts in the West and not as well-prepared for an overseas conflict. It relied on volunteers and state militia units, which faced logistical, training and food problems in the staging areas in Florida. The United States freed Cuba (after an occupation by the U.S. Army). By the peace treaty Spain ceded to the United States its colonies of Puerto Rico, Guam, and the Philippines. The Navy set up coaling stations there and in Hawaii (which voluntarily joined the U.S. in 1898). The U.S. Navy now had a major forward presence across the Pacific and (with the lease of Guantanamo Bay Naval Base in Cuba) a major base in the Caribbean guarding the approaches to the Gulf Coast and the Panama Canal.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Following the death in 1473 of James II, the last Lusignan king, the Republic of Venice assumed control of the island, while the late king's Venetian widow, Queen Catherine Cornaro, reigned as figurehead. Venice formally annexed the Kingdom of Cyprus in 1489, following the abdication of Catherine. The Venetians fortified Nicosia by building the Venetian Walls, and used it as an important commercial hub. Throughout Venetian rule, the Ottoman Empire frequently raided Cyprus. In 1539 the Ottomans destroyed Limassol and so fearing the worst, the Venetians also fortified Famagusta and Kyrenia.
In what year did James II die?
A: 1473

Context and question: 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.
Increasing pressure on the diaphragm thus increasing air output more frequently is usually caused by?
Answer: exercise

Question: The use of the term Lander (Lands) dates back to the Weimar Constitution of 1919. Before this time, the constituent states of the German Empire were called Staaten (States). Today, it is very common to use the term Bundesland (Federal Land). However, this term is not used officially, neither by the constitution of 1919 nor by the Basic Law (Constitution) of 1949. Three Lander call themselves Freistaaten (Free States, which is the old-fashioned German expression for Republic), Bavaria (since 1919), Saxony (originally since 1919 and again since 1990), and Thuringia (since 1994). There is little continuity between the current states and their predecessors of the Weimar Republic with the exception of the three free states, and the two city-states of Hamburg and Bremen.
Is there an answer to this question: Before 1919 what were the German states called?

Answer: Staaten

In the US, starting in 2013, under the Physician Financial Transparency Reports (part of the Sunshine Act), the Centers for Medicare & Medicaid Services has to collect information from applicable manufacturers and group purchasing organizations in order to report information about their financial relationships with physicians and hospitals. Data are made public in the Centers for Medicare & Medicaid Services website. The expectation is that relationship between doctors and Pharmaceutical industry will become fully transparent.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where can financial relationships between Medicaid, Medicare and pharmaceutical companies be found?
Ah, so..
