Problem: Wood:

No definite relation exists between the annual rings of growth and the amount of sapwood. Within the same species the cross-sectional area of the sapwood is very roughly proportional to the size of the crown of the tree. If the rings are narrow, more of them are required than where they are wide. As the tree gets larger, the sapwood must necessarily become thinner or increase materially in volume. Sapwood is thicker in the upper portion of the trunk of a tree than near the base, because the age and the diameter of the upper sections are less.

In what part of the tree trunk is the sapwood layer thinnest?
---
A: near the base

What period was the first known city states established in Myanmar?

Answer: Around the second century BC


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Four days after his birth, Apollo killed the chthonic dragon Python, which lived in Delphi beside the Castalian Spring. This was the spring which emitted vapors that caused the oracle at Delphi to give her prophecies. Hera sent the serpent to hunt Leto to her death across the world. To protect his mother, Apollo begged Hephaestus for a bow and arrows. After receiving them, Apollo cornered Python in the sacred cave at Delphi. Apollo killed Python but had to be punished for it, since Python was a child of Gaia.
Who was a parent of Python?
A: Gaia


Context and question: Speaking in St. Petersburg, Russia on 30 June 2011, the head of Russia's United Shipbuilding Corporation said his company expected to begin design work for a new carrier in 2016, with a goal of beginning construction in 2018 and having the carrier achieve initial operational capability by 2023. Several months later, on 3 November 2011 the Russian newspaper Izvestiya reported that the naval building plan now included (first) the construction of a new shipyard capable of building large hull ships, after which Moscow will build two (80,000 tons full load each) nuclear-powered aircraft carriers by 2027. The spokesperson said one carrier would be assigned to the Russian Navy's Northern Fleet at Murmansk, and the second would be stationed with the Pacific Fleet at Vladivostok.
Where was the Pacific Fleets nuclear-powered aircraft carrier supposed to be stationed?

Question: Sony officially unveiled PlayStation 3 (then marketed as PLAYSTATION 3) to the public on May 16, 2005, at E3 2005, along with a 'boomerang' shaped prototype design of the Sixaxis controller. A functional version of the system was not present there, nor at the Tokyo Game Show in September 2005, although demonstrations (such as Metal Gear Solid 4: Guns of the Patriots) were held at both events on software development kits and comparable personal computer hardware. Video footage based on the predicted PlayStation 3 specifications was also shown (notably a Final Fantasy VII tech demo).

Question: Freemasonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients. The degrees of freemasonry retain the three grades of medieval craft guilds, those of Apprentice, Journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by Craft (or Blue Lodge) Freemasonry. Members of these organisations are known as Freemasons or Masons. There are additional degrees, which vary with locality and jurisdiction, and are usually administered by different bodies than the craft degrees.
Is there an answer to this question: What were the fraternities of stonemasons avoiding responsibility for?

Answer:
unanswerable
