Which of the following best supports the claim that Fanny understood why she should enjoy her time with her new family?

This passage is adapted from Jane Austen, Mansfield Park. Originally published 1814. Fanny has recently moved to live with her relatives at Mansfield Park.

\[Sentence 1:\] The little girl performed her long journey in safety; and at Northampton was met by Mrs. Norris, who thus regaled in the credit of being foremost to welcome her, and in the importance of leading her in to the others, and recommending her to their kindness.

Fanny Price was at this time just ten years old, and though there might not be much in her first appearance to captivate, there was, at least, nothing to disgust her relations. She was small of her age, with no glow of complexion, nor any other striking beauty; exceedingly timid and shy, and shrinking from notice; but her air, though awkward, was not vulgar, her voice was sweet, and when she spoke her countenance was pretty. Sir Thomas and Lady Bertram received her very kindly; and Sir Thomas, seeing how much she needed encouragement, tried to be all that was conciliating: but he had to work against a most untoward gravity of deportment; and Lady Bertram, without taking half so much trouble, or speaking one word where he spoke ten, by the mere aid of a good-humored smile, became immediately the less awful character of the two.

The young people were all at home, and sustained their share in the introduction very well, with much good humor, and no embarrassment, at least on the part of the sons, who, at seventeen and sixteen, and tall of their age, had all the grandeur of men in the eyes of their little cousin. The two girls were more at a loss from being younger and in greater awe of their father, who addressed them on the occasion with rather an injudicious particularity. \[Sentence 2:\] But they were too much used to company and praise to have anything like natural shyness; and their confidence increasing from their cousin's total want of it, they were soon able to take a full survey of her face and her frock in easy indifference.

They were a remarkably fine family, the sons very well-looking, the daughters decidedly handsome, and all of them well-grown and forward of their age, which produced as striking a difference between the cousins in person, as education had given to their address; and no one would have supposed the girls so nearly of an age as they really were. There were in fact but two years between the youngest and Fanny. Julia Bertram was only twelve, and Maria but a year older.

The little visitor meanwhile was as unhappy as possible. Afraid of everybody, ashamed of herself, and longing for the home she had left, she knew not how to look up, and could scarcely speak to be heard, or without crying. \[Sentence 3\] Mrs. Norris had been talking to her the whole way from Northampton of Fanny’s wonderful good fortune, and the extraordinary degree of gratitude and good behavior which it ought to produce, and her consciousness of misery was therefore increased by the idea of its being a wicked thing for her not to be happy.

The fatigue, too, of so long a journey, became soon no trifling evil. In vain were the well-meant condescensions of Sir Thomas, and all the officious prognostications of Mrs. Norris that she would be a good girl; in vain did Lady Bertram smile and make her sit on the sofa with herself and pug, and vain was even the sight of a gooseberry tart towards giving her comfort; she could scarcely swallow two mouthfuls before tears interrupted her, and sleep seeming to be her likeliest friend, she was taken to finish her sorrows in bed.

“This is not a very promising beginning,” said Mrs. Norris, when Fanny had left the room. “After all that I said to her as we came along, I thought she would have behaved better; I told her how much might depend upon her acquitting herself well at first. I wish there may not be a little sulkiness of temper—her poor mother had a good deal; but we must make allowances for such a child—and \[Sentence 4\] I do not know that her being sorry to leave her home is really against her, for, with all its faults, it was her home, and she cannot as yet understand how much she has changed for the better; but then there is moderation in all things.”

It required a longer time, however, than Mrs. Norris was inclined to allow to reconcile Fanny to the novelty of Mansfield Park, and the separation from everybody she had been used to. Her feelings were very acute and too little understood to be properly attended to. Nobody meant to be unkind, but nobody put themselves out of their way to secure her comfort.

Fanny, whether near or from her cousins, whether in the schoolroom, the drawing-room, or the shrubbery, was equally forlorn, finding something to fear in every person and place. She was disheartened by Lady Bertram's silence, awed by Sir Thomas's grave looks, and quite overcome by Mrs. Norris's admonitions. Her elder cousins mortified her by reflections on her size, and abashed her by noticing her shyness: Miss Lee wondered at her ignorance, and the maid-servants sneered at her clothes; and when to these sorrows was added the idea of the brothers and sisters among whom she had always been important as playfellow, instructress, and nurse, the despondence that sunk her little heart was severe.

Which of the following provides the best evidence to support the following statement?

One of the reasons to improve women’s education is that doing so will ensure that men can be better educated.

Passage 1 is adapted from Emma Hart Willard, "Improving Female Education." Originally published in 1819.

\[Sentence 1\] If the improvement of the American female character, and that alone, could be affected by public liberality, employed in giving better means of instruction; such improvement of one half of society, and that half, which barbarous and despotic nations have ever degraded, would of itself be an object, worthy of the most liberal government on earth; but if the female character be raised, it must inevitably raise that of the other sex; and \[Sentence 2\] thus does the plan proposed, offer, as the object of legislative bounty, to elevate the whole character of the community.

\[Sentence 3\] As evidence that this statement does not exaggerate the female influence in society, our sex needs but be considered, in the single relation of mothers. In this character, we have the charge of the whole mass of individuals, who are to compose the succeeding generation; during that period of youth, when the pliant mind takes any direction, to which it is steadily guided by a forming hand. How important a power is given by this charge! yet, little do too many of my sex know-how, either to appreciate or improve it. Unprovided with the means of acquiring that knowledge, which flows liberally to the other sex- having our time of education devoted to frivolous acquirements, how should we understand the nature of the mind, so as to be aware of the importance of those early impressions, which we make upon the minds of our children? -or how should we be able to form enlarged and correct views, either of the character, to which we ought to mold them, or of the means most proper to form them aright?

Considered in this point of view, where the interests of male education alone to be consulted, that of females becomes of sufficient importance to engage the public attention. \[Sentence 4\] Would we rear the human plant to its perfection, we must first fertilize the soil which produces it. If it acquires its first bent and texture upon a barren plain, it will avail comparatively little, should it be afterward transplanted to a garden.

Which choice provides the best evidence for the statement below?

VWFA grows more quickly in children than it does in adults.

The following passage and corresponding figure are from Emilie Reas. "How the brain learns to read: development of the “word form area”", PLOS Neuro Community, 2018.

The ability to recognize, process and interpret written language is a uniquely human skill that is acquired with remarkable ease at a young age. But as anyone who has attempted to learn a new language will attest, the brain isn’t “hardwired” to understand written language. In fact, it remains somewhat of a mystery how the brain develops this specialized ability. Although researchers have identified brain regions that process written words, how this selectivity for language develops isn’t entirely clear.

Earlier studies have shown that the ventral visual cortex supports recognition of an array of visual stimuli, including objects, faces, and places.\[Sentence 1\] Within this area, a subregion in the left hemisphere known as the “visual word form area” (VWFA) shows a particular selectivity for written words. However, this region is characteristically plastic. It’s been proposed that stimuli compete for representation in this malleable area, such that “winner takes all” depending on the strongest input. That is, how a site is ultimately mapped is dependent on what it’s used for in early childhood. But this idea has yet to be confirmed, and the evolution of specialized brain areas for reading in children is still poorly understood.

In their study, Dehaene-Lambertz and colleagues monitored the reading abilities and brain changes of ten six-year-old children to track the emergence of word specialization during a critical development period. Over the course of their first school-year, children were assessed every two months with reading evaluations and functional MRI while viewing words and non-word images (houses, objects, faces, bodies). As expected, reading ability improved over the year of first grade, as demonstrated by increased reading speed, word span, and phoneme knowledge, among other measures.

Even at this young age, when reading ability was newly acquired, words evoked widespread left-lateralized brain activation. This activity increased over the year of school, with the greatest boost occurring after just the first few months. Importantly, there were no similar activation increases in response to other stimuli, confirming that these adaptations were specific to reading ability, not a general effect of development or education. Immediately after school began, the brain volume specialized for reading also significantly increased.\[Sentence 2\] Furthermore, reading speed was associated with greater activity, particularly in the VWFA. The researchers found that activation patterns to words became more reliable with learning. In contrast, the patterns for other categories remained stable, with the exception of numbers, which may reflect specialization for symbols (words and numbers) generally, or correlation with the simultaneous development of mathematics skills.

What predisposes one brain region over another to take on this specialized role for reading words? Before school, there was no strong preference for any other category in regions that would later become word-responsive. However, brain areas that were destined to remain “non-word” regions showed more stable responses to non-word stimuli even before learning to read. Thus, perhaps the brain takes advantage of unoccupied real-estate to perform the newly acquired skill of reading.

These findings add a critical piece to the puzzle of how reading skills are acquired in the developing child brain. Though it was already known that reading recruits a specialized brain region for words, this study reveals that this occurs without changing the organization of areas already specialized for other functions. The authors propose an elegant model for the developmental brain changes underlying reading skill acquisition. In the illiterate child, there are adjacent columns or patches of cortex either tuned to a specific category, or not yet assigned a function.\[Sentence 3\] With literacy, the free subregions become tuned to words, while the previously specialized subregions remain stable.

The rapid emergence of the word area after just a brief learning period highlights the remarkable plasticity of the developing cortex. In individuals who become literate as adults, the same VWFA is present. \[Sentence 4\] However, in contrast to children, the relation between reading speed and activation in this area is weaker in adults, and a single adult case-study by the authors showed a much slower, gradual development of the VWFA over a prolonged learning period of several months. Whatever the reason, this region appears primed to rapidly adopt novel representations of symbolic words, and this priming may peak at a specific period in childhood. This finding underscores the importance of a strong education in youth. The authors surmise that “the success of education might also rely on the right timing to benefit from the highest neural plasticity. Our results might also explain why numerous academic curricula, even in ancient civilizations, propose to teach reading around seven years.”

The figure below shows different skills mapped to different sites in the brain before schooling and then with and without school. Labile sites refer to sites that are not currently mapped to a particular skill.

Importantly, there were no similar activation increases in response to other stimuli, confirming that these adaptations were specific to reading ability, not a general effect of development or education. Immediately after school began, the brain volume specialized for reading also significantly increased. Furthermore, reading speed was associated with greater activity, particularly in the VWFA. The researchers found that activation patterns to words became more reliable with learning. In contrast, the patterns for other categories remained stable, with the exception of numbers, which may reflect specialization for symbols (words and numbers) generally, or correlation with the simultaneous development of mathematics skills.

What predisposes one brain region over another to take on this specialized role for reading words? Before school, there was no strong preference for any other category in regions that would later become word-responsive. However, brain areas that were destined to remain “non-word” regions showed more stable responses to non-word stimuli even before learning to read. Thus, perhaps the brain takes advantage of unoccupied real-estate to perform the newly acquired skill of reading.

These findings add a critical piece to the puzzle of how reading skills are acquired in the developing child brain. Though it was already known that reading recruits a specialized brain region for words, this study reveals that this occurs without changing the organization of areas already specialized for other functions. The authors propose an elegant model for the developmental brain changes underlying reading skill acquisition. In the illiterate child, there are adjacent columns or patches of cortex either tuned to a specific category, or not yet assigned a function. With literacy, the free subregions become tuned to words, while the previously specialized subregions remain stable.

The rapid emergence of the word area after just a brief learning period highlights the remarkable plasticity of the developing cortex. In individuals who become literate as adults, the same VWFA is present. However, in contrast to children, the relation between reading speed and activation in this area is weaker in adults, and a single adult case-study by the authors showed a much slower, gradual development of the VWFA over a prolonged learning period of several months. Whatever the reason, this region appears primed to rapidly adopt novel representations of symbolic words, and this priming may peak at a specific period in childhood. This finding underscores the importance of a strong education in youth. The authors surmise that “the success of education might also rely on the right timing to benefit from the highest neural plasticity. Our results might also explain why numerous academic curricula, even in ancient civilizations, propose to teach reading around seven years.”

The figure below shows different skills mapped to different sites in the brain before schooling and then with and without school. Labile sites refer to sites that are not currently mapped to a particular skill.
