Have you ever explored a cave? There are lots of passageways, cool formations, and even some creatures to see. It takes millions of years for a cave to form. Many caves are made from a soft rock called limestone. When water flows over this type of rock, it causes it to dissolve, leaving open passages and creating rooms. The water formations found in caves are called stalactites and stalagmites. They are made by the constant dripping of mineral-rich water. Some animals love the dark, wet environments that caves provide. These animals include bats, spiders, and bear.

Which piece of evidence helps explain how caves are formed?

• These animals include bats, spiders, and bears.

• It takes millions of years for a cave to form.

• When water flows over this type of rock, it causes it to dissolve, leaving open passages and creating rooms.

• The water formations found in caves are called stalactites and stalagmites.

Mars is our neighbor planet and has several interesting similarities to Earth. Mars, also known as the Red Planet, is a rocky planet with an active atmosphere. Mars has seasons, ice caps, and land form, such as volcanoes and canyons. Scientists have proven that Mars has experienced ancient flooding. One day on Mars lasts 24.6 hours, which is very similar to Earths’ 24-hour days. With all these similarities to our home planet, scientists often wonder if life will exist for humans on Mars in the future.

How does the author develop the point that Mars is like Earth?

• By showing examples of how they are related.

• By proving Mars is a better planet.

• By showing we know more about Earth than Mars.

• By giving examples of differences

Next time you pick up your electronics to listen to music or movies, you can thank James E. West. He is not well-know, but most Americans us his invention daily. Born in 1931, West was fascinated with electricity at a young age. This prompted his career as a physicist. In 1957, he worked with a fellow scientist to create a compact microphone. It is estimated that 90 percent of microphones today use his technology, including hearing aids, cell phones, headphones and laptops.

Which quote from the text supports the idea that most Americans use his invention daily?

• “…West was fascinated with electricity at a young age.”

• “This prompted his career as a physicist.”

• “…he worked with a fellow scientist to create a compact microphone”

• “…microphones today use his technology, including hearing aids, cell phones, headphones and laptops.”

Roadrunners are birds that are well adapted and important to their desert environment. They live in the southwest regions of North America. Their name comes from their habit of running along the road, usually toward cars. They do this because they are extremely territorial and want to chase away intruders. Measuring 18-24 inches in height, these birds can run up to 26 miles per hour. Their bodies do not require any extra water to drink besides what they get from their food. A roadrunner’s diet consists of a variety of insects, but they can prey on lizards and dangerous rattlesnakes.

Which quote supports the point that roadrunners are well adapted to living in the desert?

• “They live in the southwest regions of North America.”

• “They do this because they are extremely territorial and want to chase away intruders.”

• “Measuring 18-24 inches in height, these birds can run up to 26 miles per hour.”

Hot air balloons have been around since the late 1780's. The large balloon on top is called an envelope. It holds all the hot air created from an open flame. It can float upward because the air in the balloon has a lower density than the outside air. Typically, passengers and pilots ride in a basket just below the balloon. They can control where the balloon goes by adjusting the vent at the top of the envelope. Festivals are held all around the world so that people can experience this unique form of travel.

What is the author’s main point?

• Hot air balloons float in the sky.

• Hot air balloons have passengers.

• Hot air balloons float because of density.

• Hot air balloons are a unique way to travel.

• Hot air balloons have been around since the 1780's.
