While preparing a presentation on climatology, a student takes the following notes:
* Volcanic eruptions release sulfur dioxide ($SO_2$), a gas that can reflect solar radiation and lower global temperatures.
* Climatologist Marcus Thorne analyzed data from two major nineteenth-century volcanic eruptions: the 1815 eruption of Mount Tambora and the 1883 eruption of Krakatoa.
* The 1815 Mount Tambora eruption released an estimated $60\text{ million}$ tons of $SO_2$ into the atmosphere and was followed by a $0.53^\circ\text{C}$ drop in global temperatures.
* The 1883 Krakatoa eruption released an estimated $20\text{ million}$ tons of $SO_2$ and was followed by a $1.2^\circ\text{C}$ drop in global temperatures.
* Thorne claims that the volume of sulfur dioxide released is not the sole factor determining the magnitude of post-eruption global cooling.

The student wants to support Thorne's claim. Which choice most effectively uses information from the given notes to accomplish this goal?

Deep-sea shrimp of the species *Rimicaris exoculata* inhabit hydrothermal vents along the Mid-Atlantic Ridge, a habitat completely devoid of solar light. Because they reside in permanent darkness, these shrimp lack the functional compound eyes typical of other decapod crustaceans. ______ they possess a specialized dorsal organ beneath their carapace that detects faint, near-infrared thermal radiation emitted by the hot vent fluids, allowing them to navigate their environment.

While researching ancient Mediterranean merchant ships, a student took the following notes:

* The *Kyrenia* shipwreck represents a Greek merchant vessel that sank in the 4th century BCE.
* The *Kyrenia* vessel was relatively small, measuring approximately 14 meters in length.
* The *Madrague de Giens* shipwreck represents a Roman merchant vessel that sank around 75–60 BCE.
* The *Madrague de Giens* vessel was a large cargo ship, measuring approximately 40 meters in length.

The student wants to contrast the lengths of the two vessels. Which choice most effectively uses information from the given notes to accomplish this goal?

While preparing a presentation on ancient Roman history, a student takes the following notes:
* The Aqua Appia, Rome's first aqueduct, was built underground to protect the water supply from hostile forces during war.
* The Aqua Anio Vetus was constructed forty years later to meet the water demands of Rome's expanding population.
* The construction of the Aqua Anio Vetus was funded entirely by spoils taken from defeated military adversaries.
* Both aqueducts utilized gravity to transport water from distant springs into the city.

The student wants to support the claim that military conflicts influenced the design or funding of Rome's earliest aqueducts. Which choice most effectively uses information from the given notes to accomplish this goal?

While preparing a presentation on avian evolution, a student takes the following notes:
* *Microraptor gui* was a dromaeosaurid dinosaur that possessed asymmetric flight feathers on both its forelimbs and hindlimbs.
* The "ground-up" (cursorial) hypothesis proposes that flight evolved in running animals, which requires high-speed running on flat ground to generate lift.
* The "trees-down" (arboreal) hypothesis proposes that flight evolved in tree-dwelling animals that glided from elevated perches.
* Biologist Dr. Sarah Werning used aerodynamic modeling to study the effects of *Microraptor*'s long hindlimb feathers.
* The model showed that the hindlimb feathers would create excessive drag during terrestrial running but would act as stabilizing airfoils during gliding descents.

The student wants to support the claim that *Microraptor*'s physical features are more consistent with the "trees-down" hypothesis than the "ground-up" hypothesis. Which choice most effectively uses information from the notes to accomplish this goal?

For decades, historians of literacy accepted the thesis that silent reading was an exceedingly rare anomaly in the ancient Mediterranean, citing Augustine’s surprise at seeing Bishop Ambrose read without making a sound as proof of its novelty. ______ subsequent examinations of classical texts have revealed that references to reading without speaking appear in works dating back to fifth-century BCE Athens, showing that the practice was familiar to literate Greeks and Romans long before Augustine's time.

While preparing a presentation on colonial Jamaican history, a student takes the following notes:
* Maroons were communities of formerly enslaved Africans who fled plantations to establish independent settlements in the mountainous interior of Jamaica.
* Following decades of conflict, the British colonial government signed a peace treaty in 1739 with Cudjoe, leader of the Leeward Maroons.
* The treaty officially recognized Maroon autonomy, granting them land ownership and political self-governance.
* The agreement also required the Maroons to capture and return future runaway slaves to the British authorities.
* Additionally, the treaty obligated the Maroons to assist the British military in putting down future slave uprisings.

The student wants to support the claim that the 1739 treaty compromised the Maroons' alignment with other enslaved people in Jamaica despite securing their own independence. Which choice most effectively uses information from the given notes to accomplish this goal?

While conventional histories of the Silk Road emphasize the transit of luxury goods such as silk and lapis lazuli, some historians argue that the network's most profound impact was the transmission of mundane agricultural practices. ______ archaeological evidence from the Dunhuang oases indicates that regional farmers integrated West Asian irrigation designs and crop rotation systems, which permanently altered the local ecological and economic landscape.
