A Small City, Big Water Problem
Sofia's town is near a lake, so people think water will always be plentiful. But in late summer, the lake level sometimes drops, and the water gets warmer. Warmer water can hold less oxygen. Fish need that oxygen to survive. At the same time, fertilizer from nearby lawns and farms may wash into the lake after rain.

Fertilizer has nutrients that help plants grow. In water, those nutrients can make algae grow very fast. This sudden growth is called an algal bloom. At first, a bloom may look like a green paint spill on the surface. But the real problem often comes later.

When the algae die, bacteria break them down. That process uses up oxygen. So the amount of oxygen in the water can fall. As a result, fish and other animals may struggle, especially if the lake is already warm. The town noticed that fish were staying near the surface, where the oxygen was a little higher.

Local leaders talked about several fixes. They asked people to use less fertilizer and to plant native grasses near the shore. These grasses act like a filter. They slow the runoff and trap soil. The town also tested the water more often, because good choices need good information.

By early fall, the lake got better. The leaders saw that the lake's health depended on many connected things, not one single cause. Sofia realized that protecting water is not only a science problem. It is also a job for the whole community.

Based on the passage, what caused the fish to struggle in the lake?

How a Bill Becomes a Law (In a Simple Way)
In a democracy, people share power. They choose leaders, and they follow laws that apply to everyone. A law does not usually appear overnight. Instead, it is made through a careful process. A rule that affects many people should be looked at from more than one angle.

A new idea for a law often begins as a proposal. A community member might notice a problem, like unsafe crosswalks. That person can ask an elected leader to help. The leader can write the idea as a bill, which is a written plan for a possible law.

Next, a group of lawmakers may talk about the bill in a committee. They might check facts, listen to experts, and change the wording. This step matters because small changes in words can have a big effect. For example, the word "may" gives a choice, but the word "must" requires action.

After that, lawmakers talk it over and vote. If the bill passes, it may be sent to another group of lawmakers to look at again. This second check can slow things down, but it also helps stop careless choices. Finally, if leaders approve the bill, it becomes a law.

Even after a law is passed, people can see whether it works well. If it causes new problems, lawmakers can suggest changes. In this way, a democracy is not only about voting. It is also about making rules better over time.

As used in paragraph 2, what does the word proposal mean?

From Ore to Object: The Journey of Aluminum
Aluminum is used in many products, from bikes to food cans. It is light, does not rust easily, and can be shaped in many ways. But aluminum does not start out as shiny metal. It begins as a rock called bauxite. The rock must go through several steps.

First, miners take bauxite out of the ground. Then factories crush it and treat it with chemicals. This pulls out a white powder called alumina. Next, workers use electricity to turn the powder into aluminum metal. This step needs a lot of energy. So plants are often built where power is cheap.

Making new aluminum takes so much power that recycling really helps. When aluminum is recycled, it can be melted and used again. It does not have to go through every early step. So recycling can save energy. It can also lower the need for new mining. And it cuts the trash sent to dumps.

Still, recycling only works when people take part. Towns need bins and pickup programs. People must sort their trash with care. A greasy can, for example, might ruin a whole batch.

The full story of aluminum shows how small choices connect to big systems. When a student drops a can in the right bin, that small act helps save resources.

What is the author's main purpose in writing this passage?

[Paragraph 1] In a democracy, citizens have a voice in how their community is run. They can use that voice in a few ways. They can vote, speak at meetings, and contact leaders.

[Paragraph 2] Voting is one of the most familiar tools. When citizens vote, they choose leaders or decide on issues. But voting alone does not solve every problem, because leaders still need to know what people need.

[Paragraph 3] Another tool is public discussion. A town council may hold a meeting. People there share ideas about parks and roads. One speech may not change a decision. But many voices together can show what matters.

[Paragraph 4] Citizens can also write to their leaders. A clear message with reasons works well. It beats a complaint with no details.

[Paragraph 5] Taking part takes time, and not everyone agrees. Still, these tools are connected. They help leaders make choices, and they help citizens hold leaders responsible.

Which detail from the passage best supports the idea that voting is important but not enough by itself?

Read the passage, then answer the question.

Turning Sunlight into Sugar: Photosynthesis

Plants cannot walk to find food, so they make their own. The process is called photosynthesis (using sunlight to make sugar). Although it sounds like magic, it is a set of chemical steps that happen mostly in leaves.

First, a plant takes in carbon dioxide from the air through tiny openings. It also pulls water up from the soil through its roots. Inside the leaf, a green substance called chlorophyll captures light energy. This energy helps the plant combine carbon dioxide and water into sugar.

Sugar is important because it stores energy. The plant can use that energy to grow new leaves, build roots, or produce flowers. Some of the sugar may be stored for later, like saving money in a bank. In addition, oxygen is released during photosynthesis, which is one reason animals can breathe.

However, photosynthesis does not happen equally fast all the time. If a plant does not get enough light or water, the process slows. Temperature also matters, because chemical reactions often work best within a certain range. When conditions improve, photosynthesis can increase again.

Scientists measure photosynthesis to understand ecosystems, which are communities of living things and their environment. When plants make more sugar, they can support more insects and animals. Consequently, a change in sunlight or rainfall can affect many living things, not just the plants.

Which detail best supports the idea that photosynthesis affects more than just plants?

In the 1800s, many settlers in the United States moved west. Some hoped to find farmland. Others wanted to start new businesses. This movement of people is called migration.

The land itself shaped where settlers could go. Rivers helped in some places. But mountains and deserts slowed the wagons. So some routes, like passes through the mountains, became very important.

New tools also changed the trip. The telegraph let messages travel fast between faraway towns. Later, railroads joined regions and made shipping goods faster than a wagon.

But moving west was not only about speed. Settlers had to work together to get through hard weather and low supplies. For example, wagon groups shared tools, fixed wheels together, and took turns watching the animals.

Today, historians study this move west. They look at journals, maps, and photos. These show the hopes people had and the problems they faced.

What is the main idea of the passage?

Night Lights and Migrating Birds
Each spring and fall, many birds migrate. They travel long distances to find food and safer nesting places. Migration is more than a single flight. It is a pattern that happens year after year. Some birds travel at night. They use the stars, the moon, and Earth's magnetic field to help them stay on course.

In recent years, scientists have studied how city lights affect these night travelers. Bright lights can confuse birds, especially when clouds hide the stars. Instead of flying in a steady direction, some birds circle around tall buildings. This extra flying uses energy they need for the rest of their trip.

The problem gets worse during storms. Wind and rain already make flying hard, and lights can add another challenge. As a result, tired birds may land in unsafe places, such as busy streets or areas with few trees. Many birds survive, but the risk goes up when thousands migrate at once.

Some communities have tried a plan called "lights out." During the busiest migration weeks, certain buildings turn off lights they do not need at night. This does not stop migration, but it can lower confusion and help birds save energy. It also saves electricity, which is good for people and the environment.

Researchers keep studying which kinds of lights cause the most trouble and which changes help the most. The goal is not to make cities dark. The goal is to balance human needs with the needs of wildlife.

What is the relationship between storms and city lights in the passage?

The Branches of Government: Sharing Power

Many countries use systems that divide power. Putting all the power in one place can be risky. In the United States, the Constitution created three branches of government. Each branch has different jobs. Each one can also limit the others. People call this a set of checks and balances.

The legislative branch makes laws. It includes elected leaders who debate ideas and vote. The executive branch carries out the laws. That means it puts decisions into action. The judicial branch explains laws. It decides what they mean when people disagree.

These jobs are connected. For example, lawmakers may pass a law, but it might be challenged in court. If judges decide the law goes against the Constitution, it may not be used. The executive branch must follow court decisions, even if leaders disagree.

The system can feel slow, and that is partly the point. When several groups must agree, they are more likely to think a decision through. But the system also needs teamwork. If the branches refuse to work together, big problems may take longer to solve.

Understanding the branches helps people follow the news and take part in their communities. When people know who is in charge of what, they can ask better questions and make better choices.

A New Home, A New Community: Settlers and Adaptation

When settlers moved into new regions, they did not only travel across land. They also entered new climates and landscapes. Some arrived expecting to farm the same way they had before. But the soil, rain, and growing seasons were often different. So their old methods did not always work.

In one coastal area, newcomers planted crops that needed dry fields. But frequent rain flooded the rows. After several hard seasons, they watched how local Indigenous communities grew food. These communities used raised planting mounds. They also chose crops that grew well in wet ground. The settlers began to adapt. They combined their own tools with the new methods.

Adapting took more than copying. Settlers had to figure out which changes mattered most and why. For example, a raised mound did more than keep plants above water. It also warmed the soil and let water drain. When settlers understood the reasons, they could adjust the method for different fields.

Over time, the community's food changed too. People learned to use local plants and fish. They traded with neighbors for things they could not grow. This trade built friendships, but it also made them depend on certain routes and seasons.

The story shows that moving to a new place often makes people solve problems step by step. The settlers brought knowledge with them. But they did best when they stayed curious and learned from the land and from others.

Based on the passage, what can you infer about the settlers' early farming attempts?

Soil may look like plain dirt, but it is a mix of minerals, air, water, and tiny pieces of once-living things. Healthy soil supports gardens, farms, and forests.

Soil forms slowly. First, rocks break into smaller pieces through weathering. Water can freeze in cracks and push them apart, and plant roots can split rocks too. Over time, these pieces mix with rotted leaves and other bits of once-living matter.

The top layer is called topsoil. It is usually dark because it has many nutrients. Below it, subsoil has fewer nutrients and often more clay. Subsoil can hold water, but many plant roots grow best in topsoil.

Soil can be lost faster than it forms. When heavy rain hits bare ground, runoff can carry topsoil away. Wind can also move dry soil, especially in places with few plants.

Farmers and gardeners use ways to slow erosion. They may plant cover crops, leave some plant material on the ground, or build steps called terraces on slopes. These methods slow water and wind, which helps soil stay in place.

How does the last paragraph relate to the rest of the passage?

A river can look calm from a bridge, but it is always doing work. As water moves, it carries tiny pieces of rock and soil. Over time, this movement can shape the land in ways that are easy to see, like sandbars, curved banks, and wide floodplains.

The process is called erosion. Erosion means wearing away and moving bits of earth. Erosion happens faster when water flows quickly, especially after heavy rain. When a river bends, the current often hits the outside bank harder, so that side may crumble. At the same time, the inside of the bend can collect sediment and build new land.

These changes can bring both good and bad news for people. Farmers may like floodplains because the soil is often rich. But homes built too close to a shifting bank can be at risk. A river that wears away one side may also drop mud in another place, which can make boats harder to steer.

Towns have tried different fixes. Some build walls or plant trees to hold the soil in place. In other places, people move buildings farther from the river, even though it takes planning and money. Each choice has trade-offs. A wall may protect one spot but speed up erosion downstream.

Scientists and local leaders often study maps and measure how fast the water moves before they decide what to do. No plan can stop a river completely, but careful study can show where the biggest risks are. In the end, understanding erosion helps towns live with the river's slow, powerful work.

Based on the passage, why might a town decide to move buildings farther from the river instead of building a wall?

[Paragraph 1] If you have ever watched a puddle disappear after a sunny day, you have seen evaporation. That water is not gone. It is moving through the water cycle. The water cycle is a system that recycles Earth's water again and again.

[Paragraph 2] The cycle often begins when the Sun warms oceans, lakes, and damp soil. Liquid water then changes into water vapor, which is a gas. The vapor rises into the air. This change is called evaporation. Plants also release water vapor through tiny openings in their leaves. This is called transpiration.

[Paragraph 3] Higher in the sky, the air is cooler. When water vapor cools, it turns back into tiny drops. This is called condensation. The drops gather around bits of dust in the air and form clouds. Each drop is so small that it can float.

[Paragraph 4] In time, the drops bump into each other and join. When they get big enough, gravity pulls them down as precipitation. This can be rain, snow, sleet, or hail. Some water soaks into the ground. The rest flows over the land as runoff.

[Paragraph 5] Runoff can travel into streams and rivers and carry soil with it. Fast-moving water can cause erosion, which wears away rock and soil. When water slows down, it can drop the soil and form new land.

[Paragraph 6] The water cycle shows how Earth's systems are connected. Water does not follow just one path. It always keeps moving, powered by the Sun and pulled by gravity.

Which statement best summarizes the passage?

In the 1500s, ships crossed the Atlantic Ocean more often than ever before. People usually remember this time for exploration. But another kind of travel was just as important. Plants moved too. When a crop moved to a new place, it could change what people ate, how they worked, and even where they lived.

One crop that traveled far was maize. Many people today call it corn. Long before Europeans came to the Americas, Indigenous farmers had studied which seeds made the strongest plants. Over many years, they picked seeds from the best harvests. This careful work is sometimes called selective breeding. It means choosing traits on purpose. It made maize easier to grow.

After contact between continents grew, maize seeds were carried on ships to Europe. Later they reached parts of Africa and Asia. Maize spread partly because it could grow in different climates and soils. Some European grains needed cooler weather or special fields. So farmers in new areas could plant maize where other crops struggled.

But the new crop did not solve every problem. In some places, leaders pushed farmers to grow maize because it made a lot of food per acre. Yet when a community leaned on one crop too much, it was less ready for droughts, pests, or plant diseases. This risk is called dependence. It means needing something so much that it is hard to replace.

Maize also changed trade. When harvests grew, some towns had extra food to sell. Markets got bigger. As a result, more people could live in cities. There they worked at crafts and services instead of farming. Still, the benefits were not equal everywhere. Geography, weather, and local choices shaped what happened next.

Which statement best summarizes the passage?

[Paragraph 1] Long before airplanes, people traveled and traded using rivers. Rivers were like natural roads. Boats could carry heavy goods more easily than wagons on rough land.

[Paragraph 2] But rivers were not always easy to use. Some had waterfalls or shallow spots that blocked travel. In the 1800s, builders made canals to connect rivers and lakes. Canals are human-made waterways.

[Paragraph 3] Canals often had locks. A lock is a space with gates. The gates can raise or lower a boat by changing the water level. First, a boat enters and the gate closes behind it. Next, water is added or drained until the boat reaches the new height. Finally, the front gate opens and the boat moves on.

[Paragraph 4] Canals changed where people settled. Towns grew near canal routes because workers, shops, and storehouses were needed. Farmers could send crops to faraway cities. City factories could ship tools back to farm areas.

[Paragraph 5] In time, railroads became faster in many places. Even so, canals show how good building can solve land problems. They also shaped where people move and trade.

Measuring Earth's Shaking: The Richter Scale and Beyond
When the ground shakes during an earthquake, the movement can be gentle or strong. To describe earthquakes, scientists use measurements, not guesses. One early tool was the Richter scale. It compared the size of earthquake waves. A machine called a seismograph recorded the waves.

The Richter scale is special. Each whole number up stands for a much bigger change than it seems. For example, a magnitude 6 earthquake makes waves about ten times larger than a magnitude 5 earthquake. The energy also rises fast. So the difference in damage can be considerable.

But scientists do not use one number alone. They also look at where the earthquake happened and how deep it was. They check what kind of ground is nearby. Soft soil can shake more than solid rock. That can cause more damage in some neighborhoods. So two earthquakes with the same magnitude can have different effects.

Today, scientists use several scales and maps to share the risk. These tools help engineers design safer buildings. They also help towns plan emergency drills. People cannot stop earthquakes. But they can lower the harm by understanding measurements and getting ready.

As used in paragraph 2, what does the word considerable most nearly mean?

[Paragraph 1] When engineers design a bridge, they do not start by picking paint colors. First, they name the problem. The bridge must safely carry people and cars over something in the way, like a river.

[Paragraph 2] Next, engineers list criteria and constraints. Criteria are goals the design should meet, like holding a certain weight. Constraints are limits, such as a budget or the materials they can use.

[Paragraph 3] Then they build and test models. A model might be a small shape made of wood. It might also be a computer model. If a model bends too much, engineers study why it failed. Then they change the design.

[Paragraph 4] Testing happens more than once. In fact, a good bridge is usually the result of many small fixes, not one perfect idea. Engineers must also think about the weather. Wind, water, and heat can weaken parts over time.

[Paragraph 5] Finally, builders follow the plan to make the bridge. Even while it is being built, workers measure and check it. They make sure the bridge matches the design and stays safe.

As used in paragraph 2, what does the word constraints mean?

[Paragraph 1] When people talk about "going to space," they often imagine rockets and astronauts. But the motion of objects in space follows rules that scientists can measure and predict.

[Paragraph 2] An orbit is the curved path an object follows as it moves around another object in space. For example, the Moon orbits Earth. Earth, in turn, orbits the Sun.

[Paragraph 3] Gravity is the force that pulls objects toward one another. Without gravity, the Moon would travel in a straight line and drift away. But Earth's gravity pulls on the Moon. So the Moon keeps curving as it moves forward.

[Paragraph 4] Speed matters too. If an object moves too slowly, gravity will pull it down. If it moves fast enough, it can keep "falling around" a planet instead of crashing into it. This helps explain why satellites stay in orbit.

[Paragraph 5] Scientists use careful math to plan satellite launches. Computers do much of the work today. But the goal is the same: to show how gravity and speed work together to shape motion in space.

What conclusion can be drawn from the passage about why satellites stay in orbit?

[Paragraph 1] Many animals migrate. This means they move from one area to another during the year. Migration can seem strange. But it often helps animals find food, safer weather, or places to raise their young.

[Paragraph 2] One example is the monarch butterfly. In late summer and fall, monarchs in parts of North America travel very far. Some travel thousands of miles. They fly to warmer forests in Mexico and along the California coast.

[Paragraph 3] Scientists have studied how monarchs find their way. They learned that monarchs use the place of the Sun in the sky. They also use a kind of clock inside their bodies. This clock helps them adjust as the Sun moves during the day.

[Paragraph 4] Migration also has risks. Storms can blow the insects off course. Homes along the route may be lost if forests are cut down. As a result, fewer resting spots can make the trip harder.

[Paragraph 5] Migration depends on many homes that are linked together. So saving only one place is not enough. Some groups work with people in different areas. This helps monarchs finish their long trip.

According to the passage, what made migration more difficult for some monarch butterflies?

[Paragraph 1] In the early 1900s, many U.S. cities grew fast because factories offered jobs. But crowded areas created new problems. Streets often filled with trash and dirty water.

[Paragraph 2] City leaders began to study how germs spread. Scientists had shown that some illnesses could travel through dirty water. So several cities built water plants. There, the water was filtered and cleaned before it reached homes.

[Paragraph 3] Clean water helped, but it was not the only problem. In many places, garbage was dumped in open piles. Rats and flies came to the waste. They could carry disease. So cities set up regular trash pickup. They also made rules about where waste could be stored.

[Paragraph 4] These changes took planning and money. Some people complained about new taxes. Others said that public health was a shared job. Over time, the changes proved important. Fewer people got sick during outbreaks.

[Paragraph 5] Today, most people turn on a faucet without thinking. Still, clean water and trash systems were not an accident. They were built after towns studied problems and chose solutions.

Based on the passage, why did some residents likely accept higher taxes even if they did not like them?

[Paragraph 1] An ecosystem is a group of living things, like plants and animals, that live together with their surroundings. Even a small pond can be an ecosystem. Many living things there depend on one another.

[Paragraph 2] In a pond, algae and water plants catch sunlight and make food. This is called photosynthesis. These plants are called producers, and they form the base of a food web. Small insects and snails eat the plants. Then fish may eat the insects.

[Paragraph 3] Not every living thing gets energy by hunting or grazing. Decomposers, like tiny bacteria and fungi, break down dead plants and animals. This returns nutrients to the water and mud. That helps the plants grow again.

[Paragraph 4] A change in one part of the pond can affect many others. For example, if dirt blocks the sunlight, plants may grow more slowly. Then there is less food for the insects. The number of fish may drop too.

[Paragraph 5] Scientists often study a pond by looking for how things are linked. When they watch a pond over time, they can see which changes last only a little while. They can also see which ones last a long time.

As used in paragraph 3, what does the word returns most nearly mean?
