By the early 1970s Portugal's fast economic growth with increasing consumption and purchase of new automobiles set the priority for improvements in transportation. Again in the 1990s, after joining the European Economic Community, the country built many new motorways. Today, the country has a 68,732 km (42,708 mi) road network, of which almost 3,000 km (1,864 mi) are part of system of 44 motorways. Opened in 1944, the first motorway (which linked Lisbon to the National Stadium) was an innovative project that made Portugal among one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5). But, although a few other tracts were created (around 1960 and 1970), it was only after the beginning of the 1980s that large-scale motorway construction was implemented. In 1972, Brisa, the highway concessionaire, was founded to handle the management of many of the regions motorways. On many highways, toll needs to be paid, see Via Verde. Vasco da Gama bridge is the longest bridge in Europe.
How long is Portugal's total road network?
****
The answer: 68,732 km (42,708 mi)

The word "emotion" dates back to 1579, when it was adapted from the French word emouvoir, which means "to stir up". The term emotion was introduced into academic discussion to replace passion. According to one dictionary, the earliest precursors of the word likely dates back to the very origins of language. The modern word emotion is heterogeneous In some uses of the word, emotions are intense feelings that are directed at someone or something. On the other hand, emotion can be used to refer to states that are mild (as in annoyed or content) and to states that are not directed at anything (as in anxiety and depression). One line of research thus looks at the meaning of the word emotion in everyday language and this usage is rather different from that in academic discourse. Another line of research asks about languages other than English, and one interesting finding is that many languages have a similar but not identical term
From what French word is emotion derived?
****
The answer: emouvoir

On November 21, 1789, North Carolina became the twelfth state to ratify the Constitution. In 1840, it completed the state capitol building in Raleigh, still standing today. Most of North Carolina's slave owners and large plantations were located in the eastern portion of the state. Although North Carolina's plantation system was smaller and less cohesive than that of Virginia, Georgia, or South Carolina, significant numbers of planters were concentrated in the counties around the port cities of Wilmington and Edenton, as well as suburban planters around the cities of Raleigh, Charlotte, and Durham in the Piedmont. Planters owning large estates wielded significant political and socio-economic power in antebellum North Carolina, which was a slave society. They placed their interests above those of the generally non-slave-holding "yeoman" farmers of western North Carolina. In mid-century, the state's rural and commercial areas were connected by the construction of a 129-mile (208 km) wooden plank road, known as a "farmer's railroad", from Fayetteville in the east to Bethania (northwest of Winston-Salem).
North Carolina was the twelth state to ratify what document?
****
The answer: the Constitution

The problem: Answer a question about this article:
A servomotor is a motor, very often sold as a complete module, which is used within a position-control or speed-control feedback control system mainly control valves, such as motor-operated control valves. Servomotors are used in applications such as machine tools, pen plotters, and other process systems. Motors intended for use in a servomechanism must have well-documented characteristics for speed, torque, and power. The speed vs. torque curve is quite important and is high ratio for a servo motor. Dynamic response characteristics such as winding inductance and rotor inertia are also important; these factors limit the overall performance of the servomechanism loop. Large, powerful, but slow-responding servo loops may use conventional AC or DC motors and drive systems with position or speed feedback on the motor. As dynamic response requirements increase, more specialized motor designs such as coreless motors are used. AC motors' superior power density and acceleration characteristics compared to that of DC motors tends to favor PM synchronous, BLDC, induction, and SRM drive applications.
What must be well understood when applying a servo motor for use?
****
The answer:
speed, torque, and power
