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. What is red opposite to on the spectrum?
2. What is it next to?
3. what is the light's wavelength range?
4. What does RGB stand for?
5. What about RYB?

11. Is it true that when the sun is low or below the horizon, the red-wavelength decreases the light that reaches the eye?
12. What percentage of humans are redheaded?

The Standard Generalized Markup Language (SGML; ISO 8879:1986) is a standard for defining generalized markup languages for documents. ISO 8879 Annex A.1 defines generalized markup:

Generalized markup is based on two postulates:

HTML was theoretically an example of an SGML-based language until HTML 5, which admits that browsers cannot parse it as SGML (for compatibility reasons) and codifies exactly what they must do instead.

DocBook SGML and LinuxDoc are better examples, as they were used almost exclusively with actual SGML tools.

SGML is an ISO standard: "ISO 8879:1986 Information processing Text and office systems Standard Generalized Markup Language (SGML)", of which there are three versions:

SGML is part of a trio of enabling ISO standards for electronic documents developed by ISO/IEC JTC1/SC34 (ISO/IEC Joint Technical Committee 1, Subcommittee 34 Document description and processing languages) :

SGML is supported by various technical reports, in particular

SGML descended from IBM's Generalized Markup Language (GML), which Charles Goldfarb, Edward Mosher, and Raymond Lorie developed in the 1960s. Goldfarb, editor of the international standard, coined the "GML" term using their surname initials. Goldfarb also wrote the definitive work on SGML syntax in "The SGML Handbook". The syntax of SGML is closer to the COCOA format. As a document markup language, SGML was originally designed to enable the sharing of machine-readable large-project documents in government, law, and industry. Many such documents must remain readable for several decadesa long time in the information technology field. SGML also was extensively applied by the military, and the aerospace, technical reference, and industrial publishing industries. The advent of the XML profile has made SGML suitable for widespread application for small-scale, general-purpose use.

CHAPTER XXII--FIXING THE BOUNDS

Leonard came towards Normanstand next forenoon in considerable mental disturbance. In the first place he was seriously in love with Stephen, and love is in itself a disturbing influence.

Leonard's love was all of the flesh; and as such had power at present to disturb him, as it would later have power to torture him. Again, he was disturbed by the fear of losing Stephen, or rather of not being able to gain her. At first, ever since she had left him on the path from the hilltop till his interview the next day, he had looked on her possession as an 'option,' to the acceptance of which circumstances seemed to be compelling him. But ever since, that asset seemed to have been dwindling; and now he was almost beginning to despair. He was altogether cold at heart, and yet highly strung with apprehension, as he was shown into the blue drawing-room.

Stephen came in alone, closing the door behind her. She shook hands with him, and sat down by a writing-table near the window, pointing to him to sit on an ottoman a little distance away. The moment he sat down he realised that he was at a disadvantage; he was not close to her, and he could not get closer without manifesting his intention of so doing. He wanted to be closer, both for the purpose of his suit and for his own pleasure; the proximity of Stephen began to multiply his love for her. He thought that to-day she looked better than ever, of a warm radiant beauty which touched his senses with unattainable desire. She could not but notice the passion in his eyes, and instinctively her eyes wandered to a silver gong placed on the table well within reach. The more he glowed, the more icily calm she sat, till the silence between them began to grow oppressive. She waited, determined that he should be the first to speak. Recognising the helplessness of silence, he began huskily:

1. Who was Leonard's true love?
2. Was Stephen a man or a woman?
3. Where was Leonard when she left him?
4. How was Leonard feeling?
5. In what room did they meet?
6. How did she greet him?
7. Where did she want him to sit?
8. What color was the room?
9. Who spoke first?
10. Why did he feel that he was at a disadvantage?
11. What was noticeable about his eyes?
