_WHAT PRIS DID._

Priscilla, meantime, was racking her brain to discover how she could help Philip; for since she had broken off her engagement no one spoke of him to her, and she could only judge of how things were going with him by what she saw and heard as she went about her daily task.

Pris kept school, and the road which she must take twice a day led directly by the office where Phil was studying medicine with old Dr. Buffum. Formerly she always smiled and nodded as she passed, or stopped to chat a moment with the student, who usually chanced to be taking a whiff of fresh air at that instant. Little notes flew in and out, and often her homeward walk was cheered by a companion, who taught the pretty teacher lessons she found it very easy to learn.

A happy time! But it was all over now, and brief glimpses of a brown head bent above a desk near that window was the only solace poor Pris had. The head never turned as she went by, but she felt sure that Phil knew her step, and found that moment, as she did, the hardest of the day.

She longed to relent, but dared not yet. He longed to show that he repented, but found it difficult without a sign of encouragement. So they went their separate ways, seldom meeting, for Phil stuck to his books with dogged resolution, and Pris had no heart for society. 1. Who had been engaged?

input: Make use of the article to answer the questions. Red is the color at the end of the spectrum of visible light next to orange and opposite violet. Red color has a predominant light wavelength of roughly 620740 nanometres. Red is one of the additive primary colors of visible light, along with green and blue, which in Red Green Blue (RGB) color systems are combined to create all the colors on a computer monitor or television screen. Red is also one of the subtractive primary colors, along with yellow and blue, of the RYB color space and traditional color wheel used by painters and artists.

In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin. 1.

input: Make use of the article to answer the questions. Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.

Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s. The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Ampere's force law, was discovered later by Andre-Marie Ampere in 1820. The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire. This motor is often demonstrated in physics experiments, brine substituting for toxic mercury. Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century. 1.
