Problem: Neolithic:

Neolithic people were skilled farmers, manufacturing a range of tools necessary for the tending, harvesting and processing of crops (such as sickle blades and grinding stones) and food production (e.g. pottery, bone implements). They were also skilled manufacturers of a range of other types of stone tools and ornaments, including projectile points, beads, and statuettes. But what allowed forest clearance on a large scale was the polished stone axe above all other tools. Together with the adze, fashioning wood for shelter, structures and canoes for example, this enabled them to exploit their newly won farmland.

What tool allowed early manufacturers to convert forest into arable land?

Problem: For the first two years Confederate forces did well in set battles but lost control of the border states. The Confederates had the advantage of defending a very large country in an area where disease caused twice as many deaths as combat. The Union pursued a strategy of seizing the coastline, blockading the ports, and taking control of the river systems. By 1863 the Confederacy was being strangled. Its eastern armies fought well, but the western armies were defeated one after another until the Union forces captured New Orleans in 1862 along with the Tennessee River. In the famous Vicksburg Campaign of 1862–63, Ulysses Grant seized the Mississippi River and cut off the Southwest. Grant took command of Union forces in 1864 and after a series of battles with very heavy casualties, he had Lee under siege in Richmond as William T. Sherman captured Atlanta and marched through Georgia and the Carolinas. The Confederate capital was abandoned in April 1865 and Lee subsequently surrendered his army at Appomattox Court House; all other Confederate armies surrendered within a few months.
Who took control of the Snake River in 1862-63?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1609, while still there, Smyth wrote a tract titled "The Character of the Beast," or "The False Constitution of the Church." In it he expressed two propositions: first, infants are not to be baptized; and second, "Antichristians converted are to be admitted into the true Church by baptism." Hence, his conviction was that a scriptural church should consist only of regenerate believers who have been baptized on a personal confession of faith. He rejected the Separatist movement's doctrine of infant baptism (paedobaptism). Shortly thereafter, Smyth left the group, and layman Thomas Helwys took over the leadership, leading the church back to England in 1611. Ultimately, Smyth became committed to believers' baptism as the only biblical baptism. He was convinced on the basis of his interpretation of Scripture that infants would not be damned should they die in infancy.
Smyth wrote a tract titled what?
A: "The Character of the Beast," or "The False Constitution of the Church."


Context and question: The climate of New Delhi is a monsoon-influenced humid subtropical climate (Köppen Cwa) with high variation between summer and winter in terms of both temperature and rainfall. The temperature varies from 46 °C (115 °F) in summers to around 0 °C (32 °F) in winters. The area's version of a humid subtropical climate is noticeably different from many other cities with this climate classification in that it features long and very hot summers, relatively dry and mild winters, a monsoonal period, and dust storms. Summers are long, extending from early April to October, with the monsoon season occurring in the middle of the summer. Winter starts in November and peaks in January. The annual mean temperature is around 25 °C (77 °F); monthly daily mean temperatures range from approximately 14 to 34 °C (57 to 93 °F). New Delhi's highest temperature ever recorded is 49.1 °C (120.4 °F) while the lowest temperature ever recorded is −3.2 °C (26.2 °F). Those for Delhi metropolis stand at 49.9 °C (121.8 °F) and −3.2 °C (26.2 °F) respectively. The average annual rainfall is 784 millimetres (30.9 in), most of which is during the monsoons in July and August.

Question: The Eritrean highway system is named according to the road classification. The three levels of classification are: primary (P), secondary (S), and tertiary (T). The lowest level road is tertiary and serves local interests. Typically they are improved earth roads which are occasionally paved. During the wet seasons these roads typically become impassable. The next higher level road is a secondary road and typically is a single-layered asphalt road that connects district capitals together and those to the regional capitals. Roads that are considered primary roads are those that are fully asphalted (throughout their entire length) and in general they carry traffic between all the major towns in Eritrea.
Is there an answer to this question: How is the Eritrean highway system named?

Answer: according to the road classification
