Input: Read this: Each trace consists of a flat, narrow part of the copper foil that remains after etching. The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in the form of stripline and microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; but they can be used as a deliberate part of the circuit design, obviating the need for additional discrete components.
Question: For microwave boards, transmission can be laid out how?

Output: unanswerable


QUES: Forest gardening was also being used as a food production system in various parts of the world over this period. Forest gardens originated in prehistoric times along jungle-clad river banks and in the wet foothills of monsoon regions.[citation needed] In the gradual process of families improving their immediate environment, useful tree and vine species were identified, protected and improved, whilst undesirable species were eliminated. Eventually superior foreign species were selected and incorporated into the gardens.

In what kind of area did forest gardening start?
What is the answer?
ANS: jungle-clad river banks


QUES: Therapsids descended from pelycosaurs in the Middle Permian, about 265 million years ago, and became the dominant land vertebrates. They differ from basal eupelycosaurs in several features of the skull and jaws, including: larger temporal fenestrae and incisors which are equal in size. The therapsid lineage leading to mammals went through a series of stages, beginning with animals that were very like their pelycosaur ancestors and ending with probainognathian cynodonts, some of which could easily be mistaken for mammals. Those stages were characterized by:
What did the therapsid lineage do in the Middle Permian, 265 million years ago?

It was only in the 1980s that digital telephony transmission networks became possible, such as with ISDN networks, assuring a minimum bit rate (usually 128 kilobits/s) for compressed video and audio transmission. During this time, there was also research into other forms of digital video and audio communication. Many of these technologies, such as the Media space, are not as widely used today as videoconferencing but were still an important area of research. The first dedicated systems started to appear in the market as ISDN networks were expanding throughout the world. One of the first commercial videoconferencing systems sold to companies came from PictureTel Corp., which had an Initial Public Offering in November, 1984.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What other minimum bit rate is not as widely used as videoconferencing?
Ah, so.. unanswerable


Question: John, the youngest of five sons of King Henry II of England and Eleanor of Aquitaine, was at first not expected to inherit significant lands. Following the failed rebellion of his elder brothers between 1173 and 1174, however, John became Henry's favourite child. He was appointed the Lord of Ireland in 1177 and given lands in England and on the continent. John's elder brothers William, Henry and Geoffrey died young; by the time Richard I became king in 1189, John was a potential heir to the throne. John unsuccessfully attempted a rebellion against Richard's royal administrators whilst his brother was participating in the Third Crusade. Despite this, after Richard died in 1199, John was proclaimed King of England, and came to an agreement with Philip II of France to recognise John's possession of the continental Angevin lands at the peace treaty of Le Goulet in 1200.
Try to answer this question if possible: Who was Henry's favorite child?
Answer: John


Question: Brigham Young University's origin can be traced back to 1862 when a man named Warren Dusenberry started a Provo school in a prominent adobe building called Cluff Hall, which was located in the northeast corner of 200 East and 200 North. On October 16, 1875, Brigham Young, then president of the LDS Church, personally purchased the Lewis Building after previously hinting that a school would be built in Draper, Utah in 1867. Hence, October 16, 1875 is commonly held as BYU's founding date. Said Young about his vision: "I hope to see an Academy established in Provo... at which the children of the Latter-day Saints can receive a good education unmixed with the pernicious atheistic influences that are found in so many of the higher schools of the country."
Try to answer this question if possible: When was the first property for what would become BYU acquired?
Answer:
October 16, 1875
