Practice Test 7

Read the passage. Yuki wants to make her neighborhood cleaner. She notices trash near the playground after busy weekends. At first, she feels annoyed and blames other kids. Then she decides to take action instead of complaining. She asks her dad for gloves and a few large bags. On Saturday morning, she starts picking up litter with her friend Marcus. Marcus brings a grabber tool and helps separate recyclables. Soon, two younger kids ask what they are doing. Yuki explains, “We want the park to look nice for everyone.” The kids join in and collect bottles near the fence. Yuki also talks to the park manager about adding a trash can closer to the swings. The manager agrees and places one there the next week. After a month, Yuki sees less trash on the ground. She learns that small steps can lead to bigger changes. She also learns that inviting others works better than blaming them. What is the main idea of the passage?

Read the passage. In 1903, two brothers named Orville and Wilbur Wright work in Dayton, Ohio. They run a small bicycle shop and enjoy solving problems together. Many people dream of flying, but most machines cannot lift safely. The brothers study birds and also read about earlier gliders. They build a wind tunnel in their shop to test tiny wings. They measure which shapes create the most lift and least drag. Next, they design a glider and travel to Kitty Hawk, North Carolina. They choose Kitty Hawk because it has steady winds and soft sand. In 1902, their new glider turns better because of a movable tail. Still, the brothers face a big challenge: power. A glider can float, but it cannot fly far. They decide to build a light engine with help from their mechanic, Charlie Taylor. They also carve wooden propellers, treating them like spinning wings. On December 17, 1903, they try their powered airplane on the beach. Orville lies on the wing and steers while Wilbur runs beside him. The plane lifts, shakes, and then settles after a short flight. They try again three more times that morning. Each flight lasts longer, and the last one travels the farthest. The brothers feel proud, but they stay careful and keep taking notes. Their work shows that flight is possible with testing and teamwork. Soon, other inventors improve airplanes, and travel begins to change. Which of the following best summarizes the passage?
