Identifying the Main Idea Flashcards

Read the following paragraph and identify the main idea. Community gardens are becoming increasingly popular in urban areas for a multitude of reasons. They provide a space for residents, many of whom live in apartments without yards, to cultivate fresh produce, which can lead to healthier eating habits.

This answer choice best summarizes the entire paragraph. The paragraph lists multiple benefits of community gardens (health, social connections, beautification, exercise), which is what makes them popular.

Read the following paragraph: The dodo bird, a flightless bird native to the island of Mauritius, became extinct in the late 17th century. Its extinction is primarily attributed to human activities. Sailors who arrived on the island found the dodo to be an easy source of food because the bird was not afraid of humans. Additionally, the non-native species that sailors brought with them, such as dogs and pigs, preyed on the dodos and destroyed their ground nests. The combination of over-hunting and predation by invasive species quickly led to the dodo's demise.

Answer: The extinction of the dodo bird was caused by human influence, both direct and indirect.

This answer correctly identifies the central argument of the paragraph. The text explains that both direct hunting by humans and the indirect impact of the animals they introduced led to the extinction. The other options are supporting facts that explain how this happened.
