Historic Inventions
by Rupert S. Holland (adapted excerpt)

Humphrey Davy invented the safety-lamp that helped protect miners from the perils of flammable fire-damp1.

Explosions of coal-gas were only too common in the mines of England, leading to detrimental effects on those who labored underground. The biggest mine-owners met to see whether some protection against such accidents could not be devised. After much discussion, they appointed a committee to call on Sir Humphrey Davy and asked him to investigate the possibilities for them.

He took up the question, experimented with fire-damp, and found that it was in reality light carburetted hydrogen. He visited many mines and took into careful consideration the conditions under which the men worked. For months he investigated and experimented, and in 1815, he constructed the safety-lamp. This was an oil lamp, which had a chimney or cage of wire gauze that kept the flame of the lamp from passing through and igniting the fire-damp outside. The cage allowed air to pass and light to escape. Even if the combustion of the fire-damp caused the wire gauze to become red hot, it was still efficient as a safety-lamp.

from The Adventures of Tom Sawyer
by Mark Twain

SATURDAY morning was come, and all the summer world was bright and fresh, and brimming with life. There was a song in every heart; and if the heart was young the music issued at the lips. There was cheer in every face and a spring in every step . . . Tom appeared on the sidewalk with a bucket of whitewash and a long-handled brush. He surveyed the fence, and all gladness left him and a deep melancholy settled down upon his spirit. . . .
He began to think of the fun he had planned for this day, and his sorrows multiplied. Soon the free boys would come tripping along on all sorts of delicious expeditions, and they would make a world of fun of him for having to work—the very thought of it burnt him like fire. . . . At this dark and hopeless moment an inspiration burst upon him! . . .
He took up his brush and went tranquilly to work. Ben Rogers hove in sight presently—the very boy, of all boys, whose ridicule he had been dreading. Ben's gait was the hop-skip-and-jump-proof enough that his heart was light and his anticipations high. He was eating an apple, and giving a long, melodious whoop, at intervals, followed by a deep-toned ding-dong-dong, ding-dong-dong, for he was personating a steamboat. . . .
Tom went on whitewashing—paid no attention to the steamboat. Ben stared a moment and then said: "Hi-Yi! You're up a stump, ain't you!"
No answer. Tom surveyed his last touch with the eye of an artist, then he gave his brush another gentle sweep and surveyed the result, as before. Ben ranged up alongside of him. Tom's mouth watered for the apple, but he stuck to his work. Ben said:
"Hello, old chap, you got to work, hey?"
Tom wheeled suddenly and said:
"Why, it's you, Ben! I [wasn't] noticing."
"Say—I'm going in a-swimming, I am. Don't you wish you could? But of course you'd [rather] work—wouldn't you? Course you would!"
Tom contemplated the boy a bit, and said:
"What do you call work?"
"Why, ain't that work?"
Tom resumed his whitewashing, and answered carelessly: "Well, maybe it is, and maybe it ain't. All I know, is, it suits Tom Sawyer."
"Oh come, now, you don't mean to let on that you like it?" The brush continued to move.
"Like it? Well, I don't see why I oughtn't to like it. Does a boy get a chance to whitewash a fence every day?" . . .
"Say, Tom, let me whitewash a little."
Tom considered, was about to consent; but he altered his mind:
"No—no—I reckon it wouldn't hardly do, Ben. You see, Aunt Polly's awful particular about this fence . . . it's got to be done very careful; I reckon there ain't one boy in a thousand, maybe two thousand, that can do it the way it's got to be done."
"No—is that so? Oh come, now—lemme just try. Only just a little—I'd let you, if you was me, Tom."
"Ben, I'd like to, honest…but Aunt Polly—well…[if] you was to tackle this fence and anything was to happen to it—"
"Oh, shucks, I'll be just as careful. Now lemme try. Say—I'll give you the core of my apple."
"Well, here—No, Ben, now don't. I'm afeard—"
"I'll give you all of it!"
Tom gave up the brush with reluctance in his face, but alacrity in his heart. And while the late steamer Big Missouri worked and sweated in the sun, the retired artist sat on a barrel in the shade close by, dangled his legs, munched his apple, and planned the slaughter of more innocents. There was no lack of material; boys happened along every little while; they came to jeer, but remained to whitewash.

1. It is often assumed that firms are simply concerned to maximize profits: that they are not concerned with broader issues of social responsibility.

2. It is then argued, however, that competitive forces could result in society benefiting from the self-interested behaviours of firms: i.e. that profit maximization will lead to social efficiency under conditions of perfect competition and the absence of cost.

3. But, as we have seen, in the real world, markets are not perfect and there is often cost.

4. Many forms of market failure can be attributed directly to business practices that could not be classified as ‘socially responsible’: advertising campaigns that seek to misinform or in some way deceive the consumer; monopoly producers exploiting their monopoly positions through charging excessively high prices; the conscious decision to ignore water and air pollution limits; knowing that the chances of being caught are slim.

Need help please, It's urgent, which quote to support the idea....
Read the excerpt below from "Icarus" by Jean Lang.
In terror Icarus's father Daedalus watched him, and as Daedalus called to him in a voice of anguished warning that was drowned by the whistling rush of the air currents through the wings of Icarus, and there befell the dreaded thing. It seemed as though the strong wings had begun to lose their power. Like a wounded bird Icarus fluttered, lunged sidewise from the straight, clean line of his flight, recovered himself, and fluttered again. And then, like the bird into whose soft breast the sure hand of a mighty archer has driven an arrow, downwards he fell, turning over and yet turning again, downwards, ever downwards, until he fell with a plunge into the sea that still was radiant in shining emerald and translucent blue.
Then the car of Apollo drove on. His rays had slain one who was too greatly daring, and now they shone on the little white feathers that had fallen from the broken wings and floated on the water like the petals of a torn flower.
Stricken at heart was Daedalus, but there was no time to lament his son’s untimely end, for even now the ships of Minos might be in pursuit. Onward he flew to safety, and in Sicily built a temple to Apollo, and there hung up his wings as a propitiatory offering to the god who had slain his son.
Which quote best supports the idea that Icarus was reckless?
a) "Onward he flew to safety, and in Sicily built a temple to Apollo."
b) "His rays had slain one who was too greatly daring."
c) "Then the car of Apollo droveon."
