Texas 7th Grade ELA › Multiple Genres: Analyzing Informational Text for Controlling Ideas and Supporting Evidence (TEKS.ELA.7.8.D.i)
City planners increasingly treat heavy rain as a design problem, not just a weather event. When storms fall fast, water cannot soak into paved streets and parking lots. It rushes into drains, floods low spots, and carries pollution into creeks. By studying the water cycle—how water evaporates, condenses, falls as rain, and returns to the ground—planners design ways to slow, soak, and store stormwater. Rain gardens are shallow, planted basins that hold runoff long enough for soil and roots to absorb it. Permeable pavements let water pass through small gaps, reducing the volume racing into storm drains. Green roofs catch rain on top of buildings and release it slowly. Even simple changes help: disconnecting downspouts from pipes and directing them to lawns or barrels can protect basements and reduce peak flows during storms. Together, these strategies copy nature's approach to handling rain, turning hard surfaces into places where water can pause. The goal is safer streets, cleaner streams, and fewer floods.
What is the controlling idea of the article?
Rain gardens are planted depressions that hold water temporarily.
Understanding the water cycle helps cities design features that reduce flooding by slowing, soaking, and storing stormwater.
Weather affects communities around the world.
Permeable pavement allows water to seep through gaps between materials.
Explanation
Choice B captures the central idea that knowledge of the water cycle guides flood-reducing designs; the other options are supporting details or too broad.
Along the Texas coast, each hurricane season renews a lesson first learned in 1900, when a catastrophic storm struck Galveston. In the years that followed, the city raised its grade, built a seawall, and changed building practices. That pattern—experience, analysis, and improvement—continues today. Modern radar and forecasting models give residents more time to evacuate. Local officials elevate roads and hospitals, install stronger windows, and upgrade drainage to move stormwater more quickly. After Hurricane Harvey's record rainfall, communities reevaluated flood maps and added detention basins to hold runoff. Engineers also debate large-scale barriers that could limit storm surge in Galveston Bay while protecting ship channels critical to the state's economy. No system can erase risk, but Texas has steadily turned painful history into preparation. By combining better warnings with smarter infrastructure, coastal communities lower the chance that the next big storm will cause the same level of loss.
Which statement best expresses the controlling idea of the passage?
The 1900 storm flooded Galveston Island.
Barrier islands protect the mainland from waves.
Hurricanes form over warm ocean water.
Texas has steadily improved its coastal preparedness by learning from past hurricanes and investing in stronger warning systems and infrastructure.
Explanation
Choice D summarizes the central argument that Texas uses lessons from past storms to strengthen preparedness; the other choices are supporting facts or too general.
Every school day, unopened milk cartons and whole fruit often end up in the trash. That waste hurts budgets and the environment, but schools can shrink the problem with simple, student-friendly steps. A share table lets students place unopened, uneaten items where others can take them safely. Clearer serving lines—such as grouping choices by entrée and highlighting produce—help students select food they actually want. Student teams can run quick awareness campaigns, reminding classmates to try foods before tossing them. Some cafeterias schedule taste tests so new items are familiar, which reduces leftovers. Composting turns unavoidable scraps into a useful soil amendment for school gardens. Tracking what gets thrown away each week helps staff adjust portions and plan menus. None of these ideas requires expensive equipment; they rely on paying attention to what students choose and creating easy ways to redirect extras. The result is less waste, more sharing, and smarter spending.
What is the controlling idea of the passage?
Schools can significantly reduce cafeteria food waste through simple changes like share tables, clearer choices, and composting, benefiting students and budgets.
Composting turns leftover food into soil.
Some students prefer apples to oranges.
Food waste is a global problem across many countries.
Explanation
Choice A captures the passage's main argument; the other options are narrow details or overly broad statements not central to the text.
In the Permian Basin of West Texas, oil and gas drilling brings up large volumes of salty water along with energy. For years, companies disposed of most of that water in deep wells. Recently, though, many operators have begun recycling it to lower freshwater demand and reduce truck traffic. Mobile treatment units strain out sand and oil, disinfect bacteria, and blend the cleaned water so it can be reused to mix new drilling fluids. Pipelines now carry produced water between sites, replacing long lines of tankers. One mid-sized operator reported reusing about half of its water in 2023, cutting purchases of freshwater by roughly one-third during peak drilling months. Challenges remain: high salt levels can damage equipment, and disposal can still trigger concerns about earthquakes if not managed carefully. Even so, the trend is clear—recycling more water keeps projects running while easing pressure on scarce aquifers in a dry region.
Which detail best supports the passage's controlling idea that water recycling is becoming a practical solution in the Permian Basin?
Some wells are drilled horizontally to reach more rock.
Oil prices can rise and fall quickly.
One West Texas operator reported reusing about half of its water in 2023, reducing freshwater purchases by one-third.
The Permian Basin stretches across Texas and New Mexico.
Explanation
Choice C provides concrete evidence—a specific reuse result—that supports the main claim; the other choices are background or unrelated facts.
On summer afternoons, some neighborhoods feel many degrees hotter than others because of a pattern scientists call the urban heat island. One of the most effective tools for cooling cities is the urban tree canopy. Trees lower temperatures in three main ways. First, their leaves cast shade, keeping sidewalks, bus stops, and building walls from soaking up heat. Second, trees release water vapor through tiny leaf openings, a process called evapotranspiration that cools the surrounding air. Third, the presence of trees encourages cooler surfaces, such as mulched beds and lighter pavements, instead of dark asphalt that stores heat. Studies show shaded streets can be several degrees cooler than bare ones, making daily activities safer for athletes, outdoor workers, and people waiting for transportation. Some cities organize volunteer plantings near schools and transit stops, then schedule regular watering during the first years so saplings survive long, hot summers. While trees cannot end heat waves, neighborhoods with healthy canopies experience more comfortable conditions and reduced heat stress.
What is the controlling idea of the article?
Planting trees is easy if volunteers bring water and mulch.
Heat waves are becoming more common all around the world.
Urban trees help cool neighborhoods by providing shade, releasing moisture, and encouraging cooler surfaces.
City budgets should always prioritize parks over roads and buildings.
Explanation
Choice C states the controlling idea: trees cool cities through multiple mechanisms, and all paragraphs support it. A is a narrow detail, B is too broad and not the focus, and D is a policy claim not argued in the passage.
West Texas has become one of the world's leading regions for wind energy, and its growth is no accident. The area's wide-open plains and mesas offer steady, high winds that spin turbine blades for many hours each day. Large ranches provide space to place turbines in long rows while leaving room for cattle and crops. Just as important, the state invested in transmission through the Competitive Renewable Energy Zones, building high‑voltage lines to carry electricity from remote wind farms to distant cities. Those lines turned windy land into usable power for homes and businesses. The industry has also reshaped local economies: lease payments help ranchers through drought years, and maintenance crews, truck drivers, and engineers find steady work. Wind power does face challenges, including variable output during calm weather and debates about views or wildlife. Even so, the combination of geography, land access, and new power lines explains why West Texas turbines have become a major part of the state's energy mix.
Which detail best supports the article's controlling idea about why wind power expanded in West Texas?
High‑voltage transmission lines now move electricity from remote wind farms to Texas cities.
One ranch opened a small museum about early windmills on its property.
Some residents worry that turbines change the appearance of the skyline.
West Texas sunsets are especially colorful behind the turbine rows.
Explanation
The controlling idea is that wind power grew because of geography, land access, and transmission. Choice A directly shows how new lines turned remote wind into usable power. The other options are minor, aesthetic, or unrelated.
In 1900, a powerful hurricane struck Galveston, then a thriving Texas port city. With little warning, wind and water tore through homes and businesses, and thousands of lives were lost. In the disaster's aftermath, residents faced a hard question: how could Galveston survive future storms? City leaders launched bold engineering projects. Workers built a concrete seawall along the island's Gulf side to block storm surge. They also raised the grade of many neighborhoods, pumping in sand so that streets and foundations stood several feet higher than before. Houses were lifted on jacks while new, taller supports were constructed beneath them. These changes did not erase the pain of 1900, but they reshaped the city's future. The seawall has reduced damage during later storms, and the higher elevation helps channel floodwaters back to the sea. The tragedy transformed Galveston from a prosperous port into a symbol of resilience and planning, showing how communities can respond to risk with long‑term, practical solutions.
Which statement best expresses the controlling idea of the passage?
Many wooden homes in Galveston lost their porches during the storm.
Seawalls can be made of concrete and stretch for long distances along a shore.
Hurricanes usually form over warm ocean water in late summer months.
The 1900 Galveston hurricane devastated the city and led to major engineering solutions, like the seawall and raised grade, to reduce future risk.
Explanation
Choice D captures the central idea: the storm's destruction and the city's engineering response. A is a minor detail, B is a fact about materials, and C is background information not central to the passage.
School cafeterias throw away large amounts of unopened milk, whole fruit, and half‑eaten entrées each day. Many districts are finding that small changes can make a big difference in cutting waste. When one middle school set up a share table—an area where students placed unopened or unbitten items for others to take—custodians measured nearly one‑third less trash by weight over a month. Scheduling also matters: schools that switch to recess before lunch report fewer trays scraped into bins, because students aren't rushing to play. Simple food prep helps, too. Slicing apples and peeling oranges encourages students to actually eat fruit rather than toss it. Finally, giving students at least twenty minutes of seated time reduces hurried dumping at the end of the period. These adjustments don't require new kitchens or expensive equipment. By focusing on timing, presentation, and smart reuse, cafeterias keep more food on plates and out of landfills while saving money for classroom needs.
Which detail best supports the article's controlling idea that small changes can significantly reduce cafeteria food waste?
Some students do not like the taste of certain vegetables.
A share table led to nearly one‑third less trash by weight in a month‑long pilot.
One school started a garden club that meets after classes.
Compost bins are usually green and placed near the exit.
Explanation
The controlling idea is that small adjustments reduce waste. Choice B provides concrete evidence with a clear reduction. The other choices are unrelated preferences, activities, or descriptions that do not demonstrate impact.
