Read the following passage about Our Festival Traditions and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Katê Festival

Cultural diversity is a vital aspect of any society, and festivals of ethnic groups play an essential role in preserving the cultural identity of a community. Embracing cultural values through festivals is an important way of staying connected with one community as well as its history and traditions, and a well-known Katê Festival of the Chăm people in Vietnam is an example to prove so.

The Katê Festival, also known as Mbăng Katê, is the biggest yearly festival for the Chăm people in Vietnam. It is a special time of year when they honour important figures in their history and the dead in their families. The Kate Festival takes place on the first day of the seventh month in the Chăm calendar, usually in September or October. It lasts for three days and takes place around three important ancient structures in Ninh Thuận Province: the Po Klaung Yăgrai Tower, the Po Romé Tower and the Po Inû Nagar Temple. All of these places are very important to Champa culture and history.

On the morning of the first day, Cham families take part in processions as they travel to the towers and temple, bringing gifts of fruit, meat and rice. In a special ceremony, the Cham people receive the costumes of the Goddess Po Nagar from the Raglai people, a cultural group with close connections to Champa culture. The Chăm carry the costumes to the temple to celebrate Po Nagar, then they open the gates. Inside the temple, they start bathing the statues of important figures and watching sacred dances. After those performances, people enjoy lively parties until the evening of the festival's second day.

On the last day, people make special offerings to their gods at community houses in their villages and pray for luck and good health for the coming year. Once this is over, there are traditional music performances, and then people do fun activities like playing football and participating in weaving competitions.

Read the passage carefully. Choose an option (A, B, C or D) that best answers each question from 23 to 30.

1. How do children learn about wildlife? And is what they learn the sort of thing they should be learning? It is my belief that children should not just be acquiring knowledge of animals but also developing attitudes and feelings towards them based on exposure to the real lives of animals in their natural habitats. But is this happening?

2. Some research in this area indicates that it is not. Learning about animals in school is often completely disconnected from the real lives of real animals, with the result that children often end up with little or no understanding or lasting knowledge of them. They learn factual information about animals, aimed at enabling them to identify them and have various abstract ideas about them, but that is the extent of their learning. Children's storybooks tend to personify animals as characters rather than teach about them.

3. For direct contact with wild and international animals, the only opportunity most children have is visiting a zoo. The educational benefit of this for children is often given as the main reason for doing it but research has shown that zoo visits seldom add to children's knowledge of animals – the animals are simply like exhibits in a museum that the children look at without engaging with them as living creatures. Children who belong to wildlife or environmental organizations or who watch wildlife TV programmes, however, show significantly higher knowledge than any other group of children studied in research. The studies show that if children learn about animals in their natural habitats, particularly through wildlife-based activities, they know more about them than they do as a result of visiting zoos or learning about them in the classroom.

4. Research has also been done into the attitudes of children towards animals. It shows that in general terms, children form strong attachments to individual animals, usually their pets, but do not have strong feelings for animals in general. This attitude is the norm regardless of the amount or kind of learning about animals they have at school. However, those children who watch television wildlife programs show an interest in and affection for wildlife in its natural environment, and their regard for animals in general is higher.
