Problem: Memory:

One of the key concerns of older adults is the experience of memory loss, especially as it is one of the hallmark symptoms of Alzheimer's disease. However, memory loss is qualitatively different in normal aging from the kind of memory loss associated with a diagnosis of Alzheimer's (Budson & Price, 2005). Research has revealed that individuals' performance on memory tasks that rely on frontal regions declines with age. Older adults tend to exhibit deficits on tasks that involve knowing the temporal order in which they learned information; source memory tasks that require them to remember the specific circumstances or context in which they learned information; and prospective memory tasks that involve remembering to perform an act at a future time. Older adults can manage their problems with prospective memory by using appointment books, for example.

Problem: In order to explain the common features shared by Sanskrit and other Indo-European languages, many scholars have proposed the Indo-Aryan migration theory, asserting that the original speakers of what became Sanskrit arrived in what is now India and Pakistan from the north-west some time during the early second millennium BCE. Evidence for such a theory includes the close relationship between the Indo-Iranian tongues and the Baltic and Slavic languages, vocabulary exchange with the non-Indo-European Uralic languages, and the nature of the attested Indo-European words for flora and fauna.
When did the original speakers of Sanskrit migrate to the north-west?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the attempt to satisfy Austria at the time, Britain gave their electoral vote in Hanover for the candidacy of Maria Theresa's son, Joseph, as the Holy Roman Emperor, much to the dismay of Frederick and Prussia. Not only that, Britain would soon join the Austro-Russian alliance, but complications arose. Britain's basic framework for the alliance itself was to protect Hanover's interests against France. While at the same time, Kaunitz kept approaching the French in the hope of establishing such alliance with Austria. Not only that, France had no intention to ally with Russia, who meddled with their affairs in Austria's succession war, years earlier, and saw the complete dismemberment of Prussia as unacceptable to the stability of Central Europe.
What was the French view about the dismemberment of Prussia?
A: saw the complete dismemberment of Prussia as unacceptable to the stability of Central Europe.

Context and question: The president exercises a check over Congress through his power to veto bills, but Congress may override any veto (excluding the so-called "pocket veto") by a two-thirds majority in each house. When the two houses of Congress cannot agree on a date for adjournment, the president may settle the dispute. Either house or both houses may be called into emergency session by the president. The Vice President serves as president of the Senate, but he may only vote to break a tie.
Which veto is the only one Congress is able to override with a two thirds majority?
Answer: unanswerable

Question: Alloys are often made to alter the mechanical properties of the base metal, to induce hardness, toughness, ductility, or other desired properties. Most metals and alloys can be work hardened by creating defects in their crystal structure. These defects are created during plastic deformation, such as hammering or bending, and are permanent unless the metal is recrystallized. However, some alloys can also have their properties altered by heat treatment. Nearly all metals can be softened by annealing, which recrystallizes the alloy and repairs the defects, but not as many can be hardened by controlled heating and cooling. Many alloys of aluminium, copper, magnesium, titanium, and nickel can be strengthened to some degree by some method of heat treatment, but few respond to this to the same degree that steel does.
Is there an answer to this question: what is made to stabalize the properties of base metals?

Answer: unanswerable

QUES: Rendering software which cannot process a Unicode character appropriately often displays it as an open rectangle, or the Unicode "replacement character" (U+FFFD, ), to indicate the position of the unrecognized character. Some systems have made attempts to provide more information about such characters. The Apple's Last Resort font will display a substitute glyph indicating the Unicode range of the character, and the SIL International's Unicode Fallback font will display a box showing the hexadecimal scalar value of the character.

What is the glyph that Apple's Last Resort font displays?
