Main Idea (6th Grade)

Supporting Biliteracy

There are many good reasons to learn a second language. A second language can improve your understanding of your native language, open the door to new job opportunities, and help you learn about other cultures. Yet American students are less likely than European students to study foreign languages in school. To address this gap, several states have begun doing more to encourage biliteracy—the ability to read and write in two languages. California, New York, and Illinois are among the states that have passed laws establishing a state "Seal of Biliteracy." A Seal of Biliteracy shows that a student has achieved proficiency in a second language. Supporters of the seals say that they honor the importance of second-language learning. The seals also provide colleges and future employers with evidence of students' abilities.

What is the main idea of the passage?

• Although second-language learning is important, students in the United States are less likely than those in Europe to learn a second language.

• Fewer American students than European students learn a second language, so some states are supporting the study of foreign languages.

Making Towers Bird-Friendly

The lights on tall communication towers warn pilots to avoid the towers when flying at night. Unfortunately, the steady red lights often used on towers have the opposite effect on birds: the bright beams attract and confuse them. Instead of avoiding the lights, the birds fly directly toward them, crashing into the towers or becoming entangled in power lines. Millions of birds have died this way. However, there is a solution. Unlike steady lights, flashing or blinking lights don't attract birds. In response to demands from conservation groups, the Federal Aviation Administration in 2016 began requiring communication towers in the U.S. to use blinking lights instead of steady ones.

What is the main idea of this passage?

• Birds are attracted to the steady red lights on communication towers.

• To save birds, communication towers have begun using blinking lights.

The First "Newspaper" War

The Crimean War was fought in the 1850s between Russia on one side and Britain, France, and Turkey on the other. Although it was a major conflict, it is perhaps best remembered as the first war in which journalists were present on the battlefield. News dispatches from William Howard Russell, a reporter for the Times of London, exposed military blunders and revealed the filthy conditions that existed in military hospitals and camps. Photographers such as James Robertson and Roger Fenton made hundreds of photographs of soldiers on the battlefield. These news reports and photographs provided an uncensored look at life on the frontlines. The Crimean War marked the first time in history that people back home were exposed to the horrors of war.

What is the main idea of the passage?

• The Crimean war was the first war to be documented for civilians.

• The Crimean war was fought between the Russians and the British, French, and Turkish.

Saving the Rhinos

Poachers in Africa are killing large numbers of rhinos for their horns. Rhinoceros horns, valued for use in traditional medicines in Vietnam and China, can fetch as much as thirty-six thousand dollars a pound. Officials have tried to protect the rhinos: they have created fenced areas for the animals, patrolled their habitats, and even tried removing their horns. Despite these efforts, the number of rhinos in Africa has been dwindling. One creative solution to the poaching problem is to remove the rhinos from Africa altogether. Ray Dearlove, the founder of the Australian Rhino Project, came up with a plan to relocate eighty rhinos to a safari park outside Adelaide, Australia, where a breeding herd can be established.

• Officials have tried to protect African rhinos from poachers by guarding their habitats and removing their horns, but their efforts have been largely unsuccessful.

• Because other attempts to protect African rhinos from poachers have failed, the Australian Rhino Project is relocating the rhinos to Australia.

The Evolving Human Skeleton

Our early ancestors were hunter-gatherers who obtained food by hunting and by searching for edible wild plants. They needed strong bones, including large, strong jaws that enabled them to eat tough, uncooked foods. When our ancestors developed agriculture, however, their diet changed. They began growing plants, such as grains and beans, and raising animals for food; they also started cooking their foods, making them softer and easier to chew. Consequently, the human skeleton underwent radical changes. Over time, the human jaw became smaller and changed shape. Other bones also evolved, becoming lighter, especially in the joints, as result of both dietary changes and a less active lifestyle.

What is the main idea of the passage?

• As early humans developed agriculture, their bones changed significantly.

• Early humans ate uncooked meat and vegetables, so they needed strong jaws for chewing.
