Text 1
Art thou pale for weariness
Of climbing heaven and gazing on the earth,
Wandering companionless
Among the stars that have a different birth?

Text 2
Clear autumn moonlight—
a worm digs silently
into the chestnut.

(Scientific Study—More Complex Version)
Ecologists Asha Patel and colleagues studied how pollinator activity shifted with both flower pigmentation and ambient humidity. Analyzing data from community-science volunteers across four growing seasons, the researchers discovered that bees gravitated toward violet blossoms on dry days but switched to white blossoms during periods of high moisture. Additionally, nocturnal moths consistently visited pale-hued flowers regardless of weather.

According to the text, which variables were associated with pollinator preferences?*

A) Only ambient humidity, not flower color

B) Only flower color, not ambient humidity

C) Both flower color and ambient humidity, though effects varied among species

D) Neither flower color nor ambient humidity

10 (Historical Economics—Harder Version)
Economic historian Niall Ferguson has argued that state power in early modern Europe was inseparable from fiscal innovation, including systems of credit and taxation. Building on this premise, Margaret Levi and David Stasavage reconstructed archival records of Genoese bankers’ contracts, revealing that defaults by Spanish monarchs in the sixteenth century typically reflected liquidity crises tied to wartime expenditures, not insolvency in the modern sense. Their work thus reframes sovereign default as an episodic disruption within otherwise functional financial networks.

Which choice best expresses the central claim of the text?*

A) Levi and Stasavage extended prior theories of European fiscal development by showing that sovereign defaults in Spain stemmed primarily from temporary imbalances between revenue and wartime expenditure.

B) Levi and Stasavage proved that Spain’s fiscal network was uniquely resilient compared to other early modern states, despite frequent defaults on international loans.

C) Levi and Stasavage’s research indicated that Genoese bankers played an insignificant role in Spain’s credit markets, which were largely dominated by royal tax collection.

D) Levi and Stasavage concluded that Spanish defaults revealed deep structural weaknesses that would ultimately make long-term credit arrangements untenable in early modern Europe.

11 (Shakespeare—Harder Distractors)
The following is adapted from William Shakespeare’s Julius Caesar (1599). Brutus is weighing his loyalty to Caesar against his duty to the Roman Republic.

BRUTUS:
That lowliness is young ambition’s ladder,
Whereto the climber-upward turns his face;
But when he once attains the upmost round,
He then unto the ladder turns his back,
Looks in the clouds, scorning the base degrees
By which he did ascend. So Caesar may.
Then, lest he may, prevent.

Which choice best captures Brutus’s reasoning in this passage?*

A) Brutus acknowledges Caesar’s current humility but fears that once in power Caesar will spurn those who elevated him, and therefore Brutus resolves to act preemptively.

B) Brutus notes that Caesar has already turned his back on the citizens who advanced him, which justifies Brutus’s immediate move to depose him.

C) Brutus admits that his suspicions about Caesar’s ambition remain unsubstantiated but vows to defend Caesar as long as he maintains his present modesty.

D) Brutus recognizes that ambition is a virtue necessary for leadership, and therefore he urges the senators to accelerate Caesar’s ascent before rivals obstruct him.

12.
In the 1870s, photographer Eadweard Muybridge used a series of cameras to capture successive images of a galloping horse, settling a long-standing debate over whether all four hooves ever left the ground simultaneously. Muybridge’s technique of producing sequential images laid the groundwork for motion-picture technology, influencing artists and scientists alike. Painters such as Thomas Eakins and Marcel Duchamp incorporated elements of his studies into their work, while inventors later adapted the principle of sequential photography into the moving image. Still, some early filmmakers resisted this influence, favoring staged narratives rather than motion analysis.

What does the text most strongly suggest about Duchamp’s use of Muybridge’s photography?*

A) Duchamp’s artistic style relied almost exclusively on Muybridge’s sequential images of animals in motion.

B) Duchamp drew inspiration from the idea of depicting motion, though he adapted it to his own aesthetic aims.

C) Duchamp’s rejection of staged narratives set him apart from most other early twentieth-century painters.

D) Duchamp’s work demonstrated that sequential photography was more valuable to artists than to scientists.

13. Annual Fisheries Quota Compliance (2002–2004)

(Percentages show catch compared to quota; over 100% = exceeded quota)

Country	2002	2003	2004
Spain	112%	108%	115%
France	97%	103%	99%
United Kingdom	94%	96%	92%
Germany	101%	99%	105%
Italy	95%	100%	97%

In the late 1990s, the European Union created the Common Fisheries Policy (CFP) to regulate the harvesting of fish stocks in European waters. The CFP set quotas on the maximum amount of certain fish species that each member country could catch annually. If a member state exceeded its quota, penalties could be imposed, including reduced quotas in subsequent years. According to a 2002–2004 fisheries compliance report,

14.
Archaeologists recently examined burial sites from two neighboring Bronze Age cultures located in the Carpathian Basin of Central Europe. Both cultures inhabited regions with similar climates and soil types, yet chemical analysis of skeletal remains indicated distinct dietary practices. One culture consumed diets heavy in millet and dairy, while the other relied more on barley and wild game. Researchers suggest that the differences stem not from environmental necessity but from deeply ingrained cultural traditions, which may have influenced identity and group cohesion.

Which finding, if true, would most directly support the researchers’ explanation?*

A) Evidence shows that both regions could easily support the cultivation of millet, barley, and dairy production.

B) Isotopic analysis indicates that millet was significantly more abundant in one region’s soil than in the other’s.

C) Skeletal evidence reveals that the population relying more on wild game had higher rates of protein deficiency.

D) Archaeologists discovered trade goods from distant regions at both sites, indicating contact between the two cultures.

15.
A research team sought to develop new lightweight building materials that could store thermal energy, thereby improving heating efficiency in cold climates. One experimental material used a composite of recycled glass and paraffin wax, while another used concrete infused with tiny capsules of a petroleum-based phase-change substance. Testing showed that while the concrete composite could store slightly more heat overall, it was considerably heavier and more costly to produce than the recycled glass–wax composite.

Which finding, if true, would most directly support the research team’s conclusion that the recycled glass–wax composite was the more practical option?*

A) The recycled glass–wax composite maintained its energy storage capacity even after repeated cycles of heating and cooling.

B) The concrete composite stored heat for a longer duration than the recycled glass–wax composite.

C) The recycled glass–wax composite required more energy to manufacture than the concrete composite.

D) The concrete composite had greater structural strength than the recycled glass–wax composite.

16.
The Maya civilization, which flourished in Mesoamerica for centuries, developed an advanced calendar system based on careful astronomical observations.
