Here is a question about this article: In the tree a knot is either the base of a side branch or a dormant bud. A knot (when the base of a side branch) is conical in shape (hence the roughly circular cross-section) with the inner tip at the point in stem diameter at which the plant's vascular cambium was located when the branch formed as a bud.
What is the answer to this question: What measurement of a stem determines a knot's inner tip placement?

The problem: Answer a question about this article:
Besides the schism, the western church was riven by theological controversies, some of which turned into heresies. John Wycliffe (d. 1384), an English theologian, was condemned as a heretic in 1415 for teaching that the laity should have access to the text of the Bible as well as for holding views on the Eucharist that were contrary to church doctrine. Wycliffe's teachings influenced two of the major heretical movements of the later Middle Ages: Lollardy in England and Hussitism in Bohemia. The Bohemian movement initiated with the teaching of Jan Hus, who was burned at the stake in 1415 after being condemned as a heretic by the Council of Constance. The Hussite church, although the target of a crusade, survived beyond the Middle Ages. Other heresies were manufactured, such as the accusations against the Knights Templar that resulted in their suppression in 1312 and the division of their great wealth between the French King Philip IV (r. 12851314) and the Hospitallers.
Of what nationality was John Wycliffe?
****
The answer: English

Question: Read this and answer the question

The city's population increased more than sixfold during the first half of the 20th century, fed largely by an influx of European, Middle Eastern (Lebanese, Assyrian/Chaldean), and Southern migrants to work in the burgeoning automobile industry. In 1940, Whites were 90.4% of the city's population. Since 1950 the city has seen a major shift in its population to the suburbs. In 1910, fewer than 6,000 blacks called the city home; in 1930 more than 120,000 blacks lived in Detroit. The thousands of African Americans who came to Detroit were part of the Great Migration of the 20th century.

Where did the population of Detroit shift to in the second half of the 20th century?
Answer: suburbs

Input: Article: 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.

Now answer this question: In what part of the tree trunk is the sapwood layer thinnest?

Output:
near the base
