1 It has afforded the Author great amusement and satisfaction, during the progress of this work, to learn, from country friends and from a variety of ludicrous statements concerning himself in provincial newspapers, that more than one Yorkshire schoolmaster lays claim to being the original of Mr. Squeers. 2 One worthy, he has reason to believe, has actually consulted authorities learned in the law, as to his having good grounds on which to rest an action for libel; another, has meditated a journey to London, for the express purpose of committing an assault and battery on his traducer; a third, perfectly remembers being waited on, last January twelve-month, by two gentlemen, one of whom held him in conversation while the other took his likeness; and, although Mr. Squeers has but one eye, and he has two, and the published sketch does not resemble him (whoever he may be) in any other respect, still he and all his friends and neighbours know at once for whom it is meant, because—the character is so like him.

3 While the Author cannot but feel the full force of the compliment thus conveyed to him, he ventures to suggest that these contentions may arise from the fact, that Mr. Squeers is the representative of a class, and not of an individual. 4 Where imposture, ignorance, and brutal cupidity, are the stock in trade of a small body of men, and one is described by these characteristics, all his fellows will recognise something belonging to themselves, and each will have a misgiving that the portrait is his own.

How does the author view the schoolteachers’ response to his character?

1 Ye who listen with credulity to the whispers of fancy, and pursue with eagerness the phantoms of hope; who expect that age will perform the promises of youth, and that the deficiencies of the present day will be supplied by the morrow, attend to the history of Rasselas, Prince of Abyssinia.

2 … According to the custom which has descended from age to age among the monarchs of the torrid zone, Rasselas was confined in a private palace, with the other sons and daughters of Abyssinian royalty, till the order of succession should call him to the throne.

3 The place which the wisdom or policy of antiquity had destined for the residence of the Abyssinian princes was a spacious valley in the kingdom of Amhara, surrounded on every side by mountains, of which the summits overhang the middle part. 4 The only passage by which it could be entered was a cavern that passed under a rock, \[and the\] outlet of the cavern was concealed by a thick wood, and the mouth which opened into the valley was closed with gates of iron, forged by the artificers of ancient days, so massive that no man, without the help of engines, could open or shut them.

5 From the mountains on every side rivulets descended that filled all the valley with verdure and fertility, and formed a lake in the middle, inhabited by fish of every species, and frequented by every fowl whom nature has taught to dip the wing in water. 6 This lake discharged its superfluities by a stream, which entered a dark cleft of the mountain on the northern side, and fell with dreadful noise from precipice to precipice till it was heard no more.

Passage adapted from The Call of the Wild by Jack London (1903)

Again Hal's whip fell upon the dogs. They threw themselves against the breast-bands, dug their feet into the packed snow, got down low to it, and put forth all their strength. The sled held as though it were an anchor. After two efforts, they stood still, panting. The whip was whistling savagely, when once more Mercedes interfered. She dropped on her knees before Buck, with tears in her eyes, and put her arms around his neck.

"You poor, poor dears," she cried sympathetically, "why don't you pull hard?--then you wouldn't be whipped." Buck did not like her, but he was feeling too miserable to resist her, taking it as part of the day's miserable work.

One of the onlookers, who had been clenching his teeth to suppress hot speech, now spoke up:--

"It's not that I care a whoop what becomes of you, but for the dogs' sakes I just want to tell you, you can help them a mighty lot by breaking out that sled. The runners are froze fast. Throw your weight against the gee-pole, right and left, and break it out."

A third time the attempt was made, but this time, following the advice, Hal broke out the runners which had been frozen to the snow. The overloaded and unwieldy sled forged ahead, Buck and his mates struggling frantically under the rain of blows. A hundred yards ahead the path turned and sloped steeply into the main street. It would have required an experienced man to keep the top-heavy sled upright, and Hal was not such a man. As they swung on the turn the sled went over, spilling half its load through the loose lashings. The dogs never stopped. The lightened sled bounded on its side behind them. They were angry because of the ill treatment they had received and the unjust load. Buck was raging. He broke into a run, the team following his lead. Hal cried "Whoa! whoa!" but they gave no heed. He tripped and was pulled off his feet. The capsized sled ground over him, and the dogs dashed on up the street, adding to the gayety of Skaguay as they scattered the remainder of the outfit along its chief thoroughfare.

Based on the passage, it can be inferred that ________________.

Since its discovery and classification as the ninth planet in our solar system in 1930, Pluto has been the subject of much controversy in the scientific community. Its small size and extreme distance from Earth have made gathering specific data about its characteristics difficult, and no real consensus exists amongst astronomers about the information that is known about Pluto. In 2006, the International Astronomical Union created an official definition for the term "planet" which listed three criteria for classification:

1. The object must be in orbit around the sun.
2. The object must be massive enough to be rounded into a sphere by its own gravity.
3. The object must have "cleared the neighborhood" around its orbit.

Because Pluto is much smaller than the other objects in its orbit, it fails to meet the third condition and has since been known as a "dwarf planet". Some scientists have gone so far as to suggest that Pluto may actually be one of the many moons of its neighboring planet, Neptune.

When Pluto was first discovered in 1930, astronomers estimated that it may be as large as earth and thus were confident that it was, in fact, a planet. As our ability to gather information about outer space continues to improve through more powerful telescopes and space probes, scientists are now able to use the new, more accurate information they receive to accurately classify objects in space. While some still argue that Pluto meets the accepted criteria to be known as a planet, for the time being, conventional scientific thinking will hold that our solar system only has eight planets.

How were scientists able to estimate Pluto's size in 1930?
