Question 1

1. A renewed reliance on ancient authorities, especially Aristotle, as the final arbiters of truth in natural philosophy and cosmology across European universities.
2. A movement from qualitative explanations toward mathematically expressed laws derived from observation, experimentation, and predictive models of the physical universe. (correct answer)
3. A rejection of mathematics in favor of purely mystical and alchemical interpretations, emphasizing hidden sympathies rather than measurable regularities in nature.
4. A return to medieval scholasticism, prioritizing syllogistic reasoning over empirical investigation and discouraging the use of instruments like telescopes and microscopes.
5. A shift toward political absolutism, in which monarchs imposed cosmological doctrines to centralize authority and eliminate scientific debate in public institutions.

Explanation: The Scientific Revolution marked a profound change in how Europeans understood the natural world, moving away from ancient authorities like Aristotle and Ptolemy who emphasized qualitative explanations and inherent purposes in nature. Thinkers such as Copernicus, Kepler, Galileo, and Newton introduced models based on careful observation, experimentation, and mathematical precision, such as heliocentrism and laws of motion, which allowed for predictions and challenged traditional views. This shift prioritized empirical evidence and quantifiable laws over speculative philosophy, laying the foundation for modern science. Choice B captures this essence by highlighting the transition to mathematically expressed laws derived from observation and predictive models. In contrast, choices like A and D represent the older paradigms that were being overturned, while C and E misrepresent the revolution's focus on empirical and mathematical methods rather than mysticism or political control. Overall, this intellectual transformation encouraged a more systematic and verifiable approach to understanding the universe.

Question 2

1. A growing belief that society could be studied systematically and improved through reason, inspiring reform proposals grounded in universal principles and evidence. (correct answer)
2. A widespread rejection of any reform, since Newton's discoveries convinced thinkers that human institutions were unchangeable and must remain feudal.
3. An immediate end to religious practice across Europe, because scientific laws were interpreted as proof that spiritual belief was impossible.
4. A return to chivalric warfare and aristocratic privilege, as philosophers concluded mathematics could only be applied to noble bloodlines.
5. A decline in literacy and publishing, because scientific inquiry required secrecy and discouraged public debate about government and economy.

Explanation: The Scientific Revolution's view of a law-governed universe, exemplified by Newton, inspired Enlightenment thinkers to apply rational inquiry to society, fostering beliefs in systematic study and reason-based reforms, as in choice A. This led to proposals for improving politics and economics through evidence and universal principles. Choice B reverses the reformist impulse, while C overstates secularization. Choice D misapplies science to feudalism, and E denies increased literacy and debate. Thus, the Revolution laid intellectual groundwork for Enlightenment optimism in human progress.

Question 3

1. A renewed commitment to scholastic disputation, emphasizing logical reconciliation of Aristotle with Church doctrine as the primary method for producing reliable scientific knowledge.
2. A shift toward empirical observation and mathematical description of nature, elevating testing, measurement, and falsifiable claims over inherited classical and medieval authorities. (correct answer)
3. A return to purely mystical explanations of the cosmos, prioritizing hermetic symbolism and alchemical allegory above quantification and mechanical models of motion.
4. An immediate replacement of universities by craft guilds as Europe's sole centers of learning, ending elite patronage and scholarly publication networks permanently.
5. A complete rejection of Christianity by most natural philosophers, who adopted atheism as an official requirement for participation in scientific academies.

Explanation: The student's summary highlights key figures like Copernicus, Galileo, and Newton, who challenged traditional views by prioritizing empirical evidence and mathematical models over ancient authorities. This reflects a major intellectual shift during the Scientific Revolution toward empirical observation and mathematical description of nature, as described in choice B, which elevated testing and falsifiable claims. In contrast, choice A represents the older scholastic approach that the Revolution moved away from, emphasizing reconciliation of Aristotle with Church doctrine. Choice C incorrectly suggests a return to mysticism, while D overstates the decline of universities, and E exaggerates the rejection of Christianity. This change fostered a new scientific method based on evidence rather than inherited wisdom. Overall, it marked a transition from authority-based knowledge to one grounded in observation and reason.

Question 4

1. They directly challenged prevailing interpretations of Scripture and Aristotelian cosmology, threatening institutional authority over accepted truth in Catholic Europe. (correct answer)
2. They proved that planets moved in perfect circles, confirming Ptolemy and making the Church fear that astronomy would become too persuasive.
3. They showed that alchemy could transmute metals, undermining the economic monopoly of Spanish silver and prompting immediate papal condemnation.
4. They denied the existence of God and argued for materialism, forcing all European states to outlaw scientific academies by royal decree.
5. They supported witchcraft accusations by proving demons caused comets, which made Protestant leaders demand Galileo be punished by the Inquisition.

Explanation: Galileo's telescopic discoveries, such as Jupiter's moons and Venus's phases, challenged the geocentric model and Aristotelian cosmology, conflicting with Church interpretations of Scripture and threatening institutional authority, as explained in choice A. This controversy arose in Catholic Europe where religious orthodoxy was closely guarded. Choice B is inaccurate, as Galileo supported elliptical orbits, not perfect circles. Choice C confuses astronomy with alchemy, and D overstates atheism, as many scientists remained religious. Choice E wrongly links findings to witchcraft. The trial highlighted tensions between emerging science and established doctrine, yet it did not halt scientific progress overall.

Question 5

1. Women were broadly admitted to European universities by 1600, but most refused scientific study, preferring theology and canon law instead.
2. Women's scientific work frequently depended on informal settings and patronage, since institutional barriers restricted access to degrees, posts, and recognition. (correct answer)
3. Scientific societies required equal female representation, ensuring women held most leadership positions in observatories and academies across Europe.
4. The Catholic Church outlawed all female literacy, preventing any women from reading scientific texts or participating in household-based observation.
5. Women's participation was limited primarily by the absence of printing presses, since manuscripts were too expensive for women to obtain.

Explanation: Women like Maria Winkelmann contributed to science through informal channels such as family workshops and patronage, facing barriers to formal education and recognition, which supports the excerpt's argument in choice B. Social and legal restrictions limited their institutional access despite expanding scientific inquiry. Choice A is incorrect, as women were largely excluded from universities until later. Choice C overstates equality in societies, while D exaggerates Church policies. Choice E ignores printing's availability. This highlights gender inequalities persisting amid the Revolution's advancements.

Question 6

1. It reestablished geocentrism by proving that celestial bodies moved in perfect circles, restoring the authority of Ptolemy and medieval astronomical tables.
2. It provided a single set of mathematical laws explaining motion on Earth and in the heavens, reinforcing confidence in a law-governed, predictable universe. (correct answer)
3. It argued that experimentation was unnecessary because all physical truths could be deduced from scripture, ending the use of instruments in science.
4. It replaced mathematics with qualitative descriptions of nature, encouraging philosophers to abandon measurement in favor of moral interpretations of motion.
5. It demonstrated that alchemy was superior to mechanics, convincing European academies to prioritize transmutation and occult correspondences over physics.

Explanation: Isaac Newton's Principia Mathematica (1687) represented a culmination of the Scientific Revolution by synthesizing earlier discoveries into a coherent framework. It introduced universal laws of motion and gravitation that applied equally to earthly and celestial bodies, unifying phenomena like planetary orbits and falling objects. This achievement reinforced the idea of a predictable, law-governed universe, building on Kepler's elliptical orbits and Galileo's mechanics. Choice B accurately describes its significance by noting the single set of mathematical laws that bridged terrestrial and heavenly motion. Alternatives like A and C misstate its impact, such as claiming it restored geocentrism or rejected experimentation, which contradicts Newton's empirical approach. Newton's work provided a powerful model for future science, demonstrating the power of mathematical physics.

Question 7

1. Galileo's insistence that experimental findings could contradict traditional interpretations, especially regarding heliocentrism, raised concerns about undermining Church authority over doctrine. (correct answer)
2. Galileo's promotion of witchcraft prosecutions relied on astronomical omens, prompting Church leaders to condemn him for supporting popular superstition and pagan rituals.
3. Galileo's defense of the divine right of kings led Italian city-states to accuse him of sedition and to demand his trial by the Roman Inquisition.
4. Galileo's denial of the existence of God and public attacks on Christianity made him a leading atheist, forcing the papacy to silence his irreligious writings.
5. Galileo's claim that the Earth was flat contradicted maritime experience, so Catholic officials condemned him for spreading demonstrably false geographical theories.

Explanation: Galileo Galilei's work in the 17th century, particularly his telescopic discoveries like the moons of Jupiter and phases of Venus, provided strong evidence for the Copernican heliocentric model, directly challenging the geocentric views supported by the Catholic Church. This provoked controversy because it implied that traditional biblical interpretations might need revision, threatening the Church's authority over doctrine and truth. The Church feared that accepting such scientific claims could undermine its role as the ultimate arbiter of knowledge, leading to Galileo's trial by the Inquisition in 1633. Choice A correctly identifies this as the primary reason for the conflict, focusing on the tension between empirical findings and ecclesiastical authority. Other options, such as B and D, fabricate unrelated or inaccurate accusations like promoting witchcraft or atheism, which were not central to the Galileo affair. Ultimately, the episode symbolized broader struggles between emerging science and established religious institutions during this period.

Question 8

1. They replaced universities entirely, eliminating formal education so artisans alone could control scientific research without elite interference or state oversight.
2. They provided networks for verifying experiments, sharing results, and standardizing practices, helping new knowledge gain credibility beyond individual patrons or courts. (correct answer)
3. They enforced strict censorship of new theories, ensuring only Aristotelian explanations circulated and preventing the spread of mechanistic philosophies.
4. They focused primarily on theological debate, redirecting natural philosophy toward scriptural exegesis rather than observation and mathematical analysis.
5. They discouraged publication and correspondence, insisting that discoveries remain secret to protect national security and preserve traditional guild privileges.

Explanation: Scientific societies like the Royal Society in England and the Académie des Sciences in France emerged in the 17th century as crucial institutions for fostering collaboration among natural philosophers. They facilitated the sharing of experimental results through meetings, publications, and correspondence, which helped verify findings and build consensus. By providing a platform for public demonstrations and standardization of methods, these societies enhanced the credibility of new knowledge and reduced reliance on individual patrons. Choice B best explains their contribution by emphasizing networks for verification and dissemination beyond local contexts. In contrast, options like A and E exaggerate or invert their roles, such as claiming they eliminated universities or discouraged publication, which is not accurate. These societies, often supported by royal patronage, accelerated the pace of scientific progress by institutionalizing inquiry and debate.

Question 9

1. Deism and natural theology, which emphasized discovering divine order through nature and reason, often portraying God as a rational creator of lawful systems. (correct answer)
2. Iconoclasm, which sought to destroy religious images and therefore required rejecting all scientific instruments as forms of idolatrous representation.
3. Millenarianism, which insisted that all natural laws would imminently vanish, making systematic investigation meaningless and discouraging scientific inquiry.
4. Ultramontanism, which claimed the pope should directly control all laboratories and dictate experimental results to ensure theological conformity.
5. Civic republicanism, which argued that only city councils could determine astronomical truth, replacing observation with political voting procedures.

Explanation: During the Scientific Revolution, many natural philosophers sought to harmonize their discoveries with religious beliefs by viewing the study of nature as a way to appreciate God's rational design. Deism and natural theology posited that God created a lawful universe discoverable through reason and observation, often likening it to a divine mechanism. This perspective allowed mechanistic explanations to coexist with faith, as seen in works by Newton and Boyle. Choice A best describes this reconciliation, emphasizing God as a rational creator. Options like B and C distort religious movements, incorrectly linking them to rejection of science or instruments. This approach helped mitigate conflicts between science and religion, promoting inquiry as a form of worship.

Question 10

1. Instruments and print culture enabled repeatable observations and wider scrutiny of claims, accelerating debate and allowing discoveries to circulate beyond local settings. (correct answer)
2. Because instruments were banned by most governments, scientists relied on memory and oral tradition, slowing change and preventing any sustained controversy.
3. Print culture reduced literacy, so scientific works became less accessible, forcing investigators to keep results secret within monasteries and closed guilds.
4. New technologies eliminated the need for mathematics, since devices automatically produced explanations, making theoretical reasoning obsolete in natural philosophy.
5. Communication networks ended patronage, because courts refused to fund research once letters and journals replaced personal service to princes and kings.

Explanation: Technological advancements like the telescope and microscope during the Scientific Revolution expanded the scope of observable phenomena, revealing details previously inaccessible, such as microbial life or distant celestial bodies. Print culture, including books and journals, allowed for the rapid dissemination of findings, enabling scientists across Europe to scrutinize and replicate experiments. Correspondence networks further facilitated debate and collaboration, accelerating the refinement of ideas. Choice A supports the argument by highlighting how these tools enabled repeatable observations and wider scrutiny, changing the pace of knowledge production. In contrast, options like B and D misrepresent the role of technology, claiming bans or obsolescence of theory, which is not historical. Together, these developments democratized science and fostered a community of inquiry.

Question 11

1. A move from teleological explanations toward mechanistic, law-based accounts of nature, while often still assuming a divine creator behind the system. (correct answer)
2. A rejection of causation altogether, replacing explanation with purely symbolic readings of nature that denied the possibility of regularity or prediction.
3. A return to classical epic poetry as the primary scientific method, since verse was believed to preserve truth better than measurement.
4. An insistence that natural laws were unknowable, making experimentation sinful and leading to the closure of observatories and laboratories.
5. A complete replacement of Christianity with pagan polytheism, because mechanistic philosophy required worship of multiple gods controlling different forces.

Explanation: The shift during the Scientific Revolution moved from teleological explanations focused on purpose to mechanistic, law-based accounts emphasizing efficient causes, often retaining a divine creator, as outlined in choice A. Figures like Boyle and Newton integrated faith with mechanical philosophy. Choice B rejects causation entirely, which was not the case. Choice C confuses poetry with science, while D deems laws unknowable, contradicting experimentation. Choice E exaggerates religious changes. This transformation emphasized discoverable regularities, reshaping how Europeans understood nature.

Question 12

1. It reestablished the Aristotelian division between terrestrial and celestial realms, showing that different substances required separate and incompatible physics.
2. It provided a unifying mathematical framework explaining diverse phenomena, reinforcing the idea that the universe was governed by consistent natural laws. (correct answer)
3. It rejected mathematics as unreliable and argued that only sensory experience could produce knowledge, discouraging theoretical models of motion.
4. It replaced Christianity with state-sponsored deism across Europe, leading monarchs to outlaw churches and elevate scientific academies as official religions.
5. It ended European interest in astronomy by proving that planetary motion was random, making prediction impossible and observation largely pointless.

Explanation: Newton's Principia unified celestial and terrestrial physics through laws of motion and universal gravitation, providing a mathematical framework that explained diverse phenomena under consistent natural laws, as in choice B, signifying a culmination of the Scientific Revolution's mechanical philosophy. This reinforced the idea of a predictable, law-governed universe. Choice A revives the Aristotelian division Newton overcame, while C rejects his mathematical approach. Choice D exaggerates religious shifts, and E denies the predictability his work enabled. Newton's synthesis inspired later thinkers by demonstrating the power of reason to uncover universal principles.

Question 13

1. Both promoted skepticism about all knowledge and concluded that natural philosophy should be abandoned in favor of faith-based explanations of the cosmos.
2. Bacon prioritized inductive empiricism and experimentation, while Descartes stressed deductive rationalism; together they shaped scientific methods used by later investigators. (correct answer)
3. Bacon argued for heliocentrism using mathematics, while Descartes defended geocentrism using Church authority, intensifying confessional conflict within universities.
4. Bacon rejected experimentation as unreliable, while Descartes insisted only laboratory tests could produce certainty, making their approaches mutually incompatible.
5. Both insisted that ancient texts contained complete scientific truths, so their main goal was to restore classical learning rather than create new knowledge.

Explanation: Francis Bacon and René Descartes were pivotal figures in shaping the methodologies of the Scientific Revolution, each offering distinct but complementary approaches to acquiring knowledge. Bacon advocated for inductive reasoning, starting from specific observations and experiments to build general principles, emphasizing empiricism to avoid preconceived notions. Descartes, on the other hand, promoted deductive rationalism, beginning with self-evident truths and using logical deduction to arrive at conclusions, as seen in his method of doubt. Together, their ideas influenced later scientists by combining empirical data collection with rigorous logical analysis, forming the basis of the scientific method. Choice B accurately describes this relationship, noting their differing starting points yet shared goal of reliable knowledge. Choices like A and E incorrectly portray them as skeptics or restorers of ancient texts, while C and D misrepresent their views on key issues like heliocentrism and experimentation.

Question 14

1. Mechanistic philosophy, which treated matter as governed by mathematical laws of motion and minimized appeals to final causes or intrinsic purposes in nature. (correct answer)
2. Scholastic Aristotelianism, which explained motion primarily through natural places and teleology, emphasizing qualitative forms rather than quantifiable forces.
3. Humanist philology, which claimed that recovering classical Latin style would automatically yield accurate astronomical predictions and correct physical theories.
4. Baroque spiritualism, which argued that miracles regularly suspended natural laws, making prediction impossible and rendering mathematics irrelevant to nature.
5. Feudal corporatism, which explained natural order through hereditary status and customary rights, rather than through universal principles of physics.

Explanation: The 'clockwork' metaphor in the Scientific Revolution depicted the universe as a machine operating according to predictable, mathematical laws, much like a well-designed clock. This view, associated with mechanistic philosophy, emphasized matter in motion governed by impersonal forces, reducing reliance on teleological explanations or inherent purposes. Figures like Descartes and Newton promoted this worldview, contrasting it with Aristotelian ideas of natural places and qualitative essences. Choice A correctly identifies mechanistic philosophy as linked to this metaphor, highlighting its focus on quantifiable laws over intrinsic purposes. Options like B and D represent opposing or unrelated perspectives, such as scholasticism or spiritualism, which did not align with the mechanical analogy. This shift encouraged investigators to seek universal principles through observation and mathematics, influencing modern scientific thought.

Question 15

1. Women were legally prohibited from reading printed materials, so they could not learn scientific ideas even when they had access to private libraries.
2. Most universities, academies, and guild structures excluded women, limiting credentials and institutional support, even as some women contributed through salons or households. (correct answer)
3. Scientific work required military service, and women were barred from armies, so they could not participate in astronomy, physics, or medical research.
4. Women dominated scientific academies, but chose not to publish, preferring secrecy to protect discoveries from being used in commercial manufacturing.
5. The Catholic Church universally employed women as official astronomers, but Protestant states refused to recognize their authority, causing the main barriers.

Explanation: Women faced significant barriers to participation in the Scientific Revolution due to exclusion from key institutions like universities and academies, which controlled formal education and credentials. Despite this, figures like Maria Winkelmann in astronomy and Émilie du Châtelet in physics contributed through informal means, such as family collaborations or salons. These constraints stemmed from societal norms limiting women's access to professional networks and resources. Choice B accurately explains the institutional and structural limitations, even as some women found alternative paths. Alternatives like A and C fabricate prohibitions or requirements, such as bans on reading or military service, which were not primary factors. Overall, these barriers highlight how gender roles shaped the revolution's development, though women's informal roles advanced knowledge.

Question 16

1. To defend the geocentric universe by proving that celestial spheres were composed of a perfect aether inaccessible to mathematical modeling or experiment.
2. To replace reliance on tradition with a disciplined method for attaining certainty about nature, whether by induction from observations or deduction from first principles. (correct answer)
3. To restore medieval monastic control of scholarship by restricting printing and limiting scientific debate to Latin correspondence approved by bishops.
4. To argue that natural phenomena were unknowable, making skepticism the only rational stance and discouraging experiments as misleading sensory illusions.
5. To prioritize artistic realism in painting over natural philosophy, claiming perspective techniques were the most important scientific breakthrough of the era.

Explanation: Francis Bacon and René Descartes, despite their differing methods—Bacon's inductive approach from data and Descartes' deductive reasoning from principles—shared the goal of reforming knowledge production by replacing tradition with systematic methods, as in choice B. This aimed for certainty about nature through disciplined inquiry rather than reliance on ancient texts. Choice A misrepresents their intent, as they sought to advance beyond geocentric models, not defend them. Choice C is incorrect, as they promoted broader access to knowledge, not monastic restrictions. Choice D contradicts their encouragement of experimentation, and E wrongly prioritizes art over philosophy. Their combined influence helped establish the foundations of modern scientific methodology during the Revolution.

Question 17

1. They created networks for sharing results and standardizing experimental practices, making knowledge more collaborative and less dependent on isolated scholars. (correct answer)
2. They eliminated the need for instruments by proving that observation was unnecessary, since all truths about nature could be deduced from Scripture.
3. They required members to follow a single official cosmology, preventing debate so that scientific conclusions would remain politically uncontroversial.
4. They replaced universities entirely and prohibited teaching, ensuring scientific knowledge stayed private and restricted to a narrow court audience.
5. They focused chiefly on medieval alchemical secrecy, discouraging publication and making replication impossible as a safeguard against intellectual theft.

Explanation: Scientific societies like the Royal Society fostered networks for sharing results, funding, and standardizing experiments, making science more collaborative and less reliant on isolated individuals, as described in choice A. This promoted replication and public demonstration, accelerating knowledge growth. Choice B contradicts their emphasis on instruments and observation. Choice C is false, as they encouraged debate, not uniformity. Choice D overstates their replacement of universities, and E confuses them with alchemical secrecy. These institutions were crucial in institutionalizing the communal aspects of the Scientific Revolution.

Question 18

1. Kepler's mathematical laws describing elliptical orbits, which aligned predictive accuracy with a sun-centered system and reduced reliance on ad hoc epicycles. (correct answer)
2. The Council of Trent's formal endorsement of Copernicanism, which required Catholic universities to teach heliocentrism as a matter of faith.
3. The revival of Stoic ethics, which convinced most astronomers that planetary motion must be explained by moral purpose rather than physical causes.
4. The decline of printing, which reduced public controversy and allowed a single astronomical model to spread unchallenged across Europe.
5. The abandonment of mathematics in natural philosophy, since educated elites increasingly preferred purely qualitative descriptions of celestial harmony.

Explanation: Kepler's mathematical laws of planetary motion, which described elliptical orbits and improved predictive accuracy in a heliocentric system, directly strengthened acceptance of Copernican ideas by reducing the need for Ptolemaic epicycles, as stated in choice A. This built on Tycho Brahe's precise data, making heliocentrism more empirically robust. Choice B is false, as the Council of Trent did not endorse heliocentrism. Choice C misapplies Stoic ethics to astronomy, while D incorrectly claims a decline in printing, which actually aided scientific debate. Choice E reverses the trend toward mathematical emphasis in the period. Kepler's work exemplified how mathematical innovation advanced the Scientific Revolution's shift to evidence-based astronomy.

Question 19

1. They relied exclusively on Galen's texts, rejecting dissection and experimentation as impious, thereby reinforcing traditional medical authority without revision.
2. They used observation and, in Harvey's case, experimental reasoning to revise classical claims, demonstrating that empirical inquiry could overturn long-standing authorities. (correct answer)
3. They sought to align medicine with astrology, insisting that planetary positions determined anatomy and blood flow more than any physical mechanism.
4. They opposed all quantitative approaches, arguing that measurement corrupted medical judgment and that healing depended primarily on rhetorical persuasion.
5. They argued that disease resulted chiefly from demonic possession, encouraging European states to replace physicians with clergy trained in exorcism.

Explanation: Andreas Vesalius and William Harvey exemplified the Scientific Revolution's emphasis on empirical methods in medicine by challenging ancient authorities like Galen through direct observation and experimentation. Vesalius's detailed anatomical dissections revealed errors in Galen's descriptions, promoting accuracy based on human cadavers. Harvey used quantitative experiments to demonstrate blood circulation, overturning the idea of blood being consumed and regenerated. Choice B correctly explains how they reflected broader trends of revising classical claims via empirical inquiry. Options like A and C inaccurately portray them as upholding traditions or aligning with astrology, ignoring their innovative approaches. Their work encouraged a shift toward evidence-based medicine, influencing the revolution's challenge to inherited knowledge.

Question 20

1. It relied on experimental observation and the correction of ancient authorities, showing that accepted knowledge could be revised through evidence-based investigation. (correct answer)
2. It demonstrated that universities banned all hands-on research, forcing physicians to abandon anatomy and return to purely textual study of Galen.
3. It proved that disease was caused by planetary alignments, encouraging doctors to prioritize astrology over dissection and clinical experience.
4. It confirmed that classical texts were infallible, since Vesalius's dissections matched Galen perfectly and ended debate about human physiology.
5. It showed that printing had little effect on science, because Vesalius refused publication and circulated his findings only through secret manuscripts.

Explanation: Vesalius's work in anatomy, based on direct human dissections and printed illustrations that corrected Galen's errors, exemplified the Scientific Revolution's emphasis on experimental observation and revision of ancient authorities through evidence, as captured in choice A. This encouraged verification via direct investigation rather than textual deference. Choice B is wrong, as universities increasingly incorporated such research. Choice C misattributes causes to astrology, and D claims infallibility where Vesalius found flaws. Choice E ignores printing's role in dissemination. His approach promoted empirical methods that transformed medical science.
