Here is a question about this article: If a tree grows all its life in the open and the conditions of soil and site remain unchanged, it will make its most rapid growth in youth, and gradually decline. The annual rings of growth are for many years quite wide, but later they become narrower and narrower. Since each succeeding ring is laid down on the outside of the wood previously formed, it follows that unless a tree materially increases its production of wood from year to year, the rings must necessarily become thinner as the trunk gets wider. As a tree reaches maturity its crown becomes more open and the annual wood production is lessened, thereby reducing still more the width of the growth rings. In the case of forest-grown trees so much depends upon the competition of the trees in their struggle for light and nourishment that periods of rapid and slow growth may alternate. Some trees, such as southern oaks, maintain the same width of ring for hundreds of years. Upon the whole, however, as a tree gets larger in diameter the width of the growth rings decreases.
What is the answer to this question: As a tree ages, do its growth rings usually get wider or narrower?

So... narrower


Here is a question about this article: On February 11, 2004, Comcast announced a $54 billion bid for The Walt Disney Company, as well as taking on $12 billion of Disney's debt. The deal would have made Comcast the largest media conglomerate in the world. However, after rejection by Disney and uncertain response from investors, the bid was abandoned in April. The main reason for the buyout attempt was so that Comcast could acquire Disney's 80 percent stake in ESPN, which a Comcast executive called "the most important and valuable asset" that Disney owned.
What is the answer to this question: How much money did Comcast offer for this company?
****
So... $54 billion


Here is a question about this article: Parthia was a north-eastern Iranian satrapy of the Achaemenid empire which later passed on to Alexander's empire. Under the Seleucids, Parthia was governed by various Greek satraps such as Nicanor and Philip (satrap). In 247 BC, following the death of Antiochus II Theos, Andragoras, the Seleucid governor of Parthia, proclaimed his independence and began minting coins showing himself wearing a royal diadem and claiming kingship. He ruled until 238 BCE when Arsaces, the leader of the Parni tribe conquered Parthia, killing Andragoras and inaugurating the Arsacid Dynasty. Antiochus III recaptured Arsacid controlled territory in 209 BC from Arsaces II. Arsaces II sued for peace became a vassal of the Seleucids and it was not until the reign of Phraates I (168–165 BCE), that the Arsacids would again begin to assert their independence.
What is the answer to this question: When did Antiochus III regain territory from Arsaces II?
****
So...
209 BC
