Read the following passage and answer the question. "The manatee, sometimes called the 'sea cow,' is a large aquatic mammal found in the warm coastal waters of Florida. These gentle creatures can weigh up to 1,200 pounds and reach lengths of thirteen feet. Despite their massive size, manatees are herbivores, feeding primarily on seagrass and aquatic vegetation. They must surface to breathe every three to five minutes, making them vulnerable to collisions with motorboat propellers. Today, manatees are listed as a threatened species, with boat strikes accounting for a significant portion of human-caused manatee deaths each year." What is the main idea of this passage?

Read the following passage and answer the question. "Urban gardens have blossomed across cities in recent years, transforming vacant lots into productive green spaces. These gardens provide fresh vegetables to neighborhoods that often lack access to grocery stores, sometimes called 'food deserts.' Beyond food production, community gardens serve as gathering places that strengthen social bonds among neighbors. Research also suggests that access to green spaces reduces stress and improves mental health. Critics, however, argue that community gardens use land that could generate tax revenue if developed commercially." What is the author's primary purpose in writing this passage?

Vocabulary In Context
Read the following passage and answer the question. "Sleep is not a passive state. During sleep, the brain cycles through distinct stages, including REM (rapid eye movement) sleep, during which vivid dreaming occurs, and non-REM stages that facilitate physical restoration. Research shows that adults need seven to nine hours of sleep per night to maintain optimal cognitive function, emotional stability, and immune health. Chronic sleep deprivation—getting less than six hours per night for extended periods—has been linked to increased risk of cardiovascular disease, obesity, and depression."

Read the following passage and answer the question. "The Amazon rainforest, often called the 'lungs of the Earth,' stores vast quantities of carbon in its trees and soil and absorbs enormous quantities of carbon dioxide. It is home to an estimated 10% of all species on Earth and contains plants used in roughly 25% of modern medicines. Despite its critical importance, the Amazon loses millions of acres to deforestation each year, driven largely by cattle ranching, soy farming, and logging. Scientists warn that if current deforestation rates continue, the forest could reach a 'tipping point' at which it can no longer sustain itself and begins to convert to savanna." Which detail best supports the idea that the Amazon rainforest is medically important to humans?

Read the following passage and answer the question. "Some educators argue that standardized testing should be eliminated from K-12 schools. They contend that these tests create excessive stress in students, consume valuable classroom time, and fail to capture the full range of student abilities. Moreover, critics note that test results often reflect students' socioeconomic backgrounds more than their academic potential. Supporters of standardized testing, however, argue that these assessments provide objective data that helps identify achievement gaps and holds schools accountable. Without them, they claim, there would be no consistent way to measure student progress across schools and districts." Which of the following best describes the structure of this passage?

Read the following passage and answer the question. "Thomas Edison is often celebrated as the inventor of the light bulb, but the historical reality is more nuanced. Several inventors, including Humphry Davy and Joseph Swan, developed functional incandescent lamps before Edison.

Read the following passage and answer the question. "For decades, the standard advice for a healthy diet was to limit all fats. This guidance stemmed from research in the 1960s linking dietary fat to heart disease. Subsequent studies, however, revealed a more complex picture: while trans fats and excessive saturated fats remain harmful, unsaturated fats—found in olive oil, nuts, and fish—can actually reduce the risk of heart disease. Today, nutrition scientists focus less on total fat intake and more on the type of fat consumed." How has the scientific understanding of dietary fat changed according to the passage?

Before the press, books were copied by hand—a slow, expensive process that kept literacy restricted to clergy and the wealthy. The printing press made books affordable and available to a much wider audience, fueling literacy rates and enabling the rapid spread of new ideas during the Renaissance and the Protestant Reformation. By 1500, European presses had produced over 20 million books." What is the organizational structure of this passage?
