Problem: 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.

Q: CHAPTER XXIA RECOGNITION

Nothing occurred in the night to flutter the tired dove; and the dove arose refreshed. With Mr. Grewgious, when the clock struck ten in the morning, came Mr. Crisparkle, who had come at one plunge out of the river at Cloisterham.

'Miss Twinkleton was so uneasy, Miss Rosa,' he explained to her, 'and came round to Ma and me with your note, in such a state of wonder, that, to quiet her, I volunteered on this service by the very first train to be caught in the morning. I wished at the time that you had come to me; but now I think it best that you did _as_ you did, and came to your guardian.'

'I did think of you,' Rosa told him; 'but Minor Canon Corner was so near him'

'I understand. It was quite natural.'

'I have told Mr. Crisparkle,' said Mr. Grewgious, 'all that you told me last night, my dear. Of course I should have written it to him immediately; but his coming was most opportune. And it was particularly kind of him to come, for he had but just gone.'

'Have you settled,' asked Rosa, appealing to them both, 'what is to be done for Helena and her brother?'

'Why really,' said Mr. Crisparkle, 'I am in great perplexity. If even Mr. Grewgious, whose head is much longer than mine, and who is a whole night's cogitation in advance of me, is undecided, what must I be!'

The Unlimited here put her head in at the doorafter having rapped, and been authorised to present herselfannouncing that a gentleman wished for a word with another gentleman named Crisparkle, if any such gentleman were there. If no such gentleman were there, he begged pardon for being mistaken.

Answer the following questions:
1. what occurred in the night
2. who said it was quite natural
3. who was uneasy
4. who begged his pardon
5. was it considered natural by Rosa
A: 1. nothing

Problem: In a growing number of English classes, teachers are leaving the classic novels on the shelf and letting students select the books they read. Supporters say that the new approach, called reader's workshop, helps develop a love for reading in students who are bored by classic literature. They argue that the best way to motivate students to read more is to offer them more choices.

_ , however. They worry that students who choose trendy, less challenging titles over the classics won't be exposed to the great writing and key themes of important works of literature.Student reporters Donald and Sarah express their ideas about this new approach.

Donald thinks that we should turn the page. Students should be allowed to select the books they read in English class. He says he and his classmates are allowed to pick their own books in class. That makes them more focused, and they look forward to class time. Tristin, a classmate of his at Clinton Middle School agrees. "I'm reading books that I want to read, which makes class more fun and interesting," he says. Offering students a choice may also improve test scores. Studies by Professor John Guthrie of the University of Maryland found that students in grades 4 through 6 who had some choices in the books they read showed improved reading comprehension skills during testing. Giving students the chance to decide what they read helps build a lifelong love for reading. Isn't that what we want for our students?

Sarah holds a different view. She thinks teachers know more about books than students do. When an English teacher assigns a book, he or she keeps in mind the reading level of most students in the class. Students who choose their own books might be cheating themselves by picking books that are not up to their reading level or that are too difficult. Furthermore, a whole class can discuss a book it reads together. That makes it easier for some kids to understand what they are reading. "The students wouldn't be able to hold a meaningful conversation if they were all reading different books," says Kristin, an English teacher at Fleetwood Area Middle School. "If they read the same book, their conversations would be more in-depth."
