Read the passage: "The Whispering Oak" For over a century, the giant oak tree at the edge of the Miller farm stood like a silent sentinel watching over the valley. Maya leaned against its rough bark, holding her grandfather's worn leather journal. He had written of a hidden tin box buried near the tree's roots during the Summer of 1932. As storm clouds rolled in from the west, darkening the sky to a bruised purple, Maya dug into the damp soil with her small garden trowel. Her metal blade clicked against something hard. She brushed away the dirt to reveal a rusted metal latch, her heart pounding with anticipation. Based on the passage, why is Maya's heart pounding when her blade clicks against something hard?

Read the passage: "The Lighthouse Keeper's Secret" Old Thomas had kept the lantern lit at Gull Point for forty winters, never missing a single night. Young Caleb, newly appointed as his assistant, thought the work was routine and monotonous. One foggy evening, Thomas handed Caleb a brass spyglass and pointed toward the jagged reef known as the Devil's Teeth. Through the mist, Caleb spotted a small wooden fishing vessel tossed violently by the waves, its engine dead. Without a word, Thomas pulled the heavy iron lever that activated the foghorn, its deep rumble echoing across the dark water. Caleb watched in awe as Thomas calmly coordinated the rescue signal with the harbor guard, realizing for the first time that vigilance was not just a chore, but a lifeline. What evidence from the text shows why Caleb initially found the lighthouse work unexciting?

Read the passage: "The Apprentice’s Choice" In the bustling ceramic workshop of 18th-century Charleston, Master Masterson examined Julian's latest clay pitcher. The handle was slightly lopsided, but the intricate floral pattern etched into the side was breathtaking. 'Precision comes first, lad,' Masterson grumbled, tapping the uneven handle with a wooden ruler. 'A vessel that spills is worthless, no matter how pretty it looks.' Julian swallowed his pride and nodded. He knew his master valued structural perfection above all. Yet, as Julian stared at the raw gray clay on his wheel that afternoon, he resolved to master both strength and beauty, refusing to sacrifice his artistic vision for mere utility. How does Master Masterson's perspective on pottery differ from Julian's perspective?

Read the two texts: Passage 4A (Historical Fiction Excerpt): The Iron Charger rattled down the narrow mountain pass as smoke billowed into the midnight air. Engineer Arthur Vance strained against the squealing brake lever. Sparks flew from the iron wheels like miniature fireworks. Beside him, young stoker Billy shoveled coal with frantic energy, his face blackened by soot. 'She’s going too fast, Arthur!' Billy yelled over the deafening roar. Arthur set his jaw, staring into the dark gorge ahead. He knew that if they didn't slow the train before Deadman’s Curve, the locomotive would leap from the rails. Passage 4B (Historical Account Excerpt): On October 14, 1895, Locomotive No. 42 encountered mechanical brake failure while descending the Saluda Grade in South Carolina. Chief Engineer Arthur Vance and fireman William 'Billy' Higgins were aboard. Records indicate that despite severe brake wear, Vance successfully managed engine back-pressure to reduce momentum, bringing the train to a halt three hundred yards past Deadman’s Curve without derailment or injury to the crew. Which element is featured in the historical fiction excerpt (Passage 4A) but absent from the historical account (Passage 4B)?

Read the passage: "The Resilience of Salt Marshes" South Carolina's coastal salt marshes are among the most productive ecosystems on Earth. These wetland areas, dominated by smooth cordgrass (Spartina alterniflora), act as natural buffers against coastal storms. During hurricanes, marsh vegetation absorbs wave energy and traps sediment, reducing shoreline erosion and protecting inland communities from storm surges. Additionally, salt marshes serve as crucial nurseries for marine life, providing shelter and nutrients for young shrimp, crabs, and commercial fish species. However, rising sea levels and coastal development pose significant threats to marsh survival, prompting conservationists to construct living shorelines using oyster reefs to bolster marsh resilience.

Read the passage: "The Invention of the Telegraph" Before the 1830s, long-distance communication moved no faster than a galloping horse or a sailing ship. That changed dramatically when Samuel Morse, along with his associate Alfred Vail, perfected the electric telegraph. By sending electrical impulses along a wire, the telegraph allowed messages to travel instantly over hundreds of miles. Morse and Vail also developed Morse Code, a system of dots and dashes representing letters of the alphabet. In 1844, Morse sent the first official telegraph message—'What hath God wrought'—from Washington, D.C., to Baltimore.

Read the passage: "Deep-Sea Hydrothermal Vents" Thousands of meters below the ocean surface, where sunlight cannot penetrate, temperatures hover near freezing and water pressure is crushing. In 1977, oceanographers made a startling discovery along the Galápagos Rift: hydrothermal vents spewing mineral-rich water heated to over 700°F (370°C) by sub-seafloor magma. Surprisingly, these pitch-black environments were teeming with unique life forms, including giant tube worms, blind shrimp, and ghost crabs. Instead of relying on photosynthesis powered by sunlight, these ecosystems rely on chemosynthesis. Bacteria at the vents convert toxic hydrogen sulfide gas from the vents into organic energy, forming the base of a thriving deep-sea food web. What does the term chemosynthesis mean as explained in the passage?
