Problem: Melbourne:

During a visit in 1885 English journalist George Augustus Henry Sala coined the phrase "Marvellous Melbourne", which stuck long into the twentieth century and is still used today by Melburnians. Growing building activity culminated in a "land boom" which, in 1888, reached a peak of speculative development fuelled by consumer confidence and escalating land value. As a result of the boom, large commercial buildings, coffee palaces, terrace housing and palatial mansions proliferated in the city. The establishment of a hydraulic facility in 1887 allowed for the local manufacture of elevators, resulting in the first construction of high-rise buildings; most notably the APA Building, amongst the world's tallest commercial buildings upon completion in 1889. This period also saw the expansion of a major radial rail-based transport network.

In what year was the APA Building completed?

A: 1889


Problem: An example of this theory in action would be as follows: An emotion-evoking stimulus (snake) triggers a pattern of physiological response (increased heart rate, faster breathing, etc.), which is interpreted as a particular emotion (fear). This theory is supported by experiments in which by manipulating the bodily state induces a desired emotional state. Some people may believe that emotions give rise to emotion-specific actions: e.g. "I'm crying because I'm sad," or "I ran away because I was scared." The issue with the James–Lange theory is that of causation (bodily states causing emotions and being a priori), not that of the bodily influences on emotional experience (which can be argued and is still quite prevalent today in biofeedback studies and embodiment theory).
 In the James-Lange theory, what doesn't cause emotions?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
South America became linked to North America through the Isthmus of Panama during the Pliocene, bringing a nearly complete end to South America's distinctive marsupial faunas. The formation of the Isthmus had major consequences on global temperatures, since warm equatorial ocean currents were cut off and an Atlantic cooling cycle began, with cold Arctic and Antarctic waters dropping temperatures in the now-isolated Atlantic Ocean. Africa's collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. Sea level changes exposed the land-bridge between Alaska and Asia. Near the end of the Pliocene, about 2.58 million years ago (the start of the Quaternary Period), the current ice age began. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years.
How often does the cycle of rising sea levels repeat?
A: unanswerable


Context and question: In February 2007, the fourth and last satellite of the BeiDou-1 system, BeiDou-1D (sometimes called BeiDou-2A, serving as a backup satellite), was sent up into space. It was reported that the satellite had suffered from a control system malfunction but was then fully restored.
What happened to the BeiDou-1D satellite that needed to be repaired?
Answer: a control system malfunction


Question: In Asia, various Chinese dynasties and Japanese shogunates controlled the Asian sphere. In Japan, the Edo period from 1600 to 1868 is also referred to as the early modern period. And in Korea, from the rising of Joseon Dynasty to the enthronement of King Gojong is referred to as the early modern period. In the Americas, Native Americans had built a large and varied civilization, including the Aztec Empire and alliance, the Inca civilization, the Mayan Empire and cities, and the Chibcha Confederation. In the west, the European kingdoms and movements were in a movement of reformation and expansion. Russia reached the Pacific coast in 1647 and consolidated its control over the Russian Far East in the 19th century.
Is there an answer to this question: What is time is considered the "Modern Period" in Korea?

Answer: from the rising of Joseon Dynasty to the enthronement of King Gojong


Problem: Buddhism:

Unlike many religions, Buddhism has no single central text that is universally referred to by all traditions. However, some scholars have referred to the Vinaya Pitaka and the first four Nikayas of the Sutta Pitaka as the common core of all Buddhist traditions.[page needed] This could be considered misleading, as Mahāyāna considers these merely a preliminary, and not a core, teaching. The Tibetan Buddhists have not even translated most of the āgamas (though theoretically they recognize them) and they play no part in the religious life of either clergy or laity in China and Japan. Other scholars say there is no universally accepted common core. The size and complexity of the Buddhist canons have been seen by some (including Buddhist social reformer Babasaheb Ambedkar) as presenting barriers to the wider understanding of Buddhist philosophy.

What has been seen by some as a hinderance to understanding Buddhist philosophy?
---
A:
size and complexity of the Buddhist canons
