In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Article: The term culture now is more used to describe everything from the fine arts to the outlook of a business group or a sports team. In its original sense, however, culture includes all identifying aspects of a racial group, nation, or empire: its physical environment, history, and traditions, its social rules and economic structure, and its religious beliefs and arts. The central beliefs and customs of a group are handed down from one generation to another. It is for this reason that most people regard culture as learned rather than innate. People acquire a culture because they are not born with one. The process by which a person develops a taste for regional foods, accented speech, or an outlook on the world over time, therefore, is known as enculturation . Cultures are often identified by their symbols -- images that are familiar and coated with meaning. Totem poles carved with animals and creative figures suggest aspects of the Native American peoples of the Pacific Northwest but more literally represent specific tribes. In Asia and India, the color1 of yellow is connected with temples while in ancient China it was a color1 only the emperor's family was allowed to wear. Thus, different cultures may respond to a symbol quite differently. For example, to some a flag may represent pride, historical accomplishments, or ideals; to others, however, it can mean danger or oppression. To individuals unfamiliar with cultures outside their own, the beliefs, behaviors, and artistic expression of other groups can seem strange and even threatening. A society that ranks all other cultures against its own standards is considered to be ethnocentric (from the Greek ethnos, meaning "people," and kentros, meaning "center"). A strongly ethnocentric society assumes also that what is different from its own culture is likely to be inferior and, possibly, wrong or evil. All people are ethnocentric to some degree, and some aspects of ethnocentrism, such as national pride, contribute to a well-functioning society. An appreciation for one's own culture, however, does not prevent acceptance and respect for another culture. History documents the long-term vigor and success of multicultural groups in which people from numerous and various cultural backgrounds live and work together. Extreme ethnocentrism, in contrast, can lead to racism -- the belief that it is race and racial origin that account for variations in human character or ability and that one's own race is superior to all others.
Answer: Culture, a distinctive identity of a nation
Which might be the best title of the passage?

Article: We live in a culture that sends out very mixed messages about mistakes: We're told we learn by making them, but we work hard to avoid them. So the result is that most of us know that we are going to make mistakes, but deep down, we feel we shouldn't. Experiments with schoolchildren who did well on a given test show that those who were praised for being smart and then offered a more challenging or less challenging task afterward usually chose the easier one. On the other hand, children praised for trying hard-- rather than being smart--far more often selected the more difficult task. If we try hard to avoid mistakes, we aren't open to getting the information we need in order to do better. In a writing study, experiments showed that those who are so scared to make mistakes perform worse in writing tasks than those who aren't as worried about being perfect. They fear receiving any kind of negative feedback, so they don't learn where they went wrong and how to get better. We don't just learn more when we're open to mistakes, we learn deeper. Research tells us that if we're only concerned about getting the right answer, we don't always learn the underlying concepts that help us truly understand whatever we're trying to figure out. Mistakes need to be seen not as a failure to learn, but as a guide to what still needs to be learned. As Thomas Edison said, "I am not discouraged, because every abandoned wrong attempt is another step forward." Furthermore, we often make mistakes because we try new things--we wander away from accepted paths. Teflon, penicillin--these are examples of great discoveries made by mistake. Take a page from Albert Einstein, who said, "Anyone who has never made a mistake has never tried anything new. "
Answer: He will choose a less challenging task.
What will happen to students praised for being smart in face of choosing tasks compared to students praised for working hard?

Article: Imagine when you are sailing an ocean for the first time, you see a big fish swimming near your ship. You might be scared, and worried about whether it will turn over your ship for a meal. In fact, it is not a fish at all, but a gentle giant whale. Whales are not fishes but mammals . Their body temperature stays the same, and does not change with the temperature of their environment. They breathe air, so they have to come out of the water to get oxygen. Thus, they cannot afford to fall into a sleeping state for too long, since they need to be awake in order to breathe. It is thought that only half of their brains sleep at a time, so that whales are never completely asleep. Females give birth to the young. They have hair. Although they are not covered in hair or fur like many mammals, whales have some bristles , usually on their heads. Whales are highly social animals with complex languages and intelligence. They communicate with each other using romantic sounds, called "whale songs". Being so large and powerful, these sounds are also loud. Whales are endangered as a result of whaling from the eleventh century to the twentieth. It has attracted the attention of environmentalists and some measures have been taken to protect whales.
