Problem: Portugal:

Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and/or personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975. By 2007, Portugal had 10,617,575 inhabitants of whom about 332,137 were legal immigrants.

Problem: The Spanish language is the second most spoken language in the United States. There are 45 million Hispanophones who speak Spanish as a first or second language in the United States, as well as six million Spanish language students. Together, this makes the United States of America the second largest Hispanophone country in the world after Mexico, and with the United States having more Spanish-speakers than Colombia and Spain (but fewer first language speakers). Spanish is the Romance language and the Indo-European language with the largest number of native speakers in the world. Roughly half of all American Spanish-speakers also speak English "very well," based on their self-assessment in the U.S. Census.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Upon this basis, along with that of the logical content of assertions (where logical content is inversely proportional to probability), Popper went on to develop his important notion of verisimilitude or "truthlikeness". The intuitive idea behind verisimilitude is that the assertions or hypotheses of scientific theories can be objectively measured with respect to the amount of truth and falsity that they imply. And, in this way, one theory can be evaluated as more or less true than another on a quantitative basis which, Popper emphasises forcefully, has nothing to do with "subjective probabilities" or other merely "epistemic" considerations.
What was Popper's unimportant notion?
A: unanswerable

Context and question: Whereas most Christians believe the gibbet on which Jesus was executed was the traditional two-beamed cross, the Jehovah's Witnesses hold the view that a single upright stake was used. The Greek and Latin words used in the earliest Christian writings are ambiguous. The Koine Greek terms used in the New Testament are stauros () and xylon (). The latter means wood (a live tree, timber or an object constructed of wood); in earlier forms of Greek, the former term meant an upright stake or pole, but in Koine Greek it was used also to mean a cross. The Latin word crux was also applied to objects other than a cross.
What is the nature of the words Jehovah's Witnesses use to describe wood?
Answer: unanswerable

Question: The Appalachian belt includes, with the ranges enumerated above, the plateaus sloping southward to the Atlantic Ocean in New England, and south-eastward to the border of the coastal plain through the central and southern Atlantic states; and on the north-west, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains. A remarkable feature of the belt is the longitudinal chain of broad valleys, including The Great Appalachian Valley, which in the southerly sections divides the mountain system into two unequal portions, but in the northernmost lies west of all the ranges possessing typical Appalachian features, and separates them from the Adirondack group. The mountain system has no axis of dominating altitudes, but in every portion the summits rise to rather uniform heights, and, especially in the central section, the various ridges and intermontane valleys have the same trend as the system itself. None of the summits reaches the region of perpetual snow.
Is there an answer to this question: What divides the mountain range equally?

Answer: unanswerable

QUES: Breakthrough pain is transitory acute pain that comes on suddenly and is not alleviated by the patient's normal pain management. It is common in cancer patients who often have background pain that is generally well-controlled by medications, but who also sometimes experience bouts of severe pain that from time to time "breaks through" the medication. The characteristics of breakthrough cancer pain vary from person to person and according to the cause. Management of breakthrough pain can entail intensive use of opioids, including fentanyl.

What activity in relation to breakthrough pain requires heavy use of opiods?
