question: Fifty-two years ago in the USA, a little black girl named Ruby Bridges arrived at her new primary school. The school was in New Orleans, Louisiana.

As she walked toward the school's front door, an angry crowd of people shouted at her. United States marshals walked with her. A marshal is a police officer. They were there to protect the first grader. That's because the people didn't want Ruby to go inside the school. But the 6-year-old walked into the school anyway. As she did, she marched into history books.

The day was Nov. 14, 1960. On that morning, little Ruby became one of the first African Americans to attend an all-white primary school in the South.

Before then, the law in many states said that black children could not attend the same schools as white children. People of different races also had to use separate public restrooms. It was called segregation. That is when people of different races are kept separate.

U.S. leaders worked to end segregation. They helped bring civil rights to all Americans. Those are the rights mean that all people should be treated equally. A few months before Ruby started school, a federal court had just ordered an end to school segregation in New Orleans.

By the time Ruby started the second grade, there were no more angry people outside her school. There were other African American students in her class. Today, children of all races go to school together.

Bridges said she was never scared to go to school during the first grade. She wasn't really afraid and she didn't really know what was going on at the time.

A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.

It is not an SI unit, as the SI unit of angular measure is the radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians.

The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Persian calendar, used 360 days for a year. The use of a calendar with 360 days may be related to the use of sexagesimal numbers.

Another theory is that the Babylonians subdivided the circle using the angle of an equilateral triangle as the basic unit and further subdivided the latter into 60 parts following their sexagesimal numeric system. The earliest trigonometry, used by the Babylonian astronomers and their Greek successors, was based on chords of a circle. A chord of length equal to the radius made a natural base quantity. One sixtieth of this, using their standard sexagesimal divisions, was a degree. What are the answers to this following set of questions: 1. How many degrees are in a full circle?
2. Is it an SI unit?
Answer: 1. 360 degrees
2. no

input: Make use of the article to answer the questions. Audrey Hepburn won an Academy Award as Best Actress for her first major American movie, Roman Holiday, which was showed in 1953. But she is remembered as much for her help as for her acting. Born in Belgium in 1929, Audrey's father was British and her mother was Dutch. Audrey was sent to live at a British school for part of her childhood. During World war II, she lived and studied in the Netherlands. Her mother thought it would be safe from German attacks. Audrey studied dance as a teenager and during college. But when she returned to London after the war she realized she wasn't going to be a ballet dancer. So she began taking acting parts in stage shows. Later she began to get small parts in movies. But it was Audrey Hepburn's move to America that made her truly famous. In 1951 she played the character "Gigi" in the Broadway play Gigi and won popular praise. Two years later, Roman Holiday made her a star at the age of 24. Audrey made more than 25 movies. Among her most popular roles was "Hoolly Golinghtly" in Breakfast at Tiffany's in 1961. Three years later she played "Eliza Doolittle" in My Fair Lady. She was married twice. In 1989, the UN Children's Fund named Audrey a goodwill ambassador. She travelled all over the world in support of UNICEF projects. The UN agency said she was a tireless worker. She often gave 15 interviews a day to raise money and get support for UNICEF projects. Audrey Hepburn often said her love to UNICEF was the result of her experiences as a child during World War II. She said she knew what it was like to be hungry and to be saved by international help. She was a goodwill ambassador until her death in 1993 from cancer. 1. who is the story about?
