“Khi cách mạng đã lên rồi, Cắm trở về làng. Ồ, cái thằng bé gọi Cắm bằng chú. Coi kìa! Nó đã trở thành một thằng con trai lớn tồng ngồng. Cái lưng nó đã rộng bè bè và hơi cong lại như lưng một con thú rừng sắp vồ mồi. Tóc nó đen và dài. Và cặp mắt nó thì đích thị là cặp mắt của một người Mèo thực sự, xếch lên một chút, sáng như hai đốm lửa trong rừng khuya và sâu đến nao lòng những cô gái nào vô tình nhìn vào đấy. Mới đầu, nó không nhận ra Cắm. Cái thằng bé!”

(Nguyên Ngọc, Rẻo cao)

Farmers and companies are developing solutions for (632) _____. In Canada and Brazil, farmers started adding a special ingredient to their animals' feed to reduce cows' methane production.

The masks will allow cows to continue their normal diet but will turn methane into CO2 and water. They can fit comfortably on the cow's head and can be adjusted to different head sizes. Sensors on the masks can notice when methane comes out of the cow's mouth and provide the percentage of the gas (634)_____. This information can also be useful for farmers who can use it to (635) __________ the early signs of disease. For example, if a cow eats less, but produces more methane than usual, it may have a health problem.

It is predicted that the need for beef and dairy products will go up in the coming years. The company developing the methane-catching masks hopes that farmers will start using their invention, which will slow down global warming.

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.

In which paragraph does the passage describe how the festival begins?

Read the passage carefully. Choose an option (A, B, C or D) that best answers each question from 16 to 22.

1. Like many emergency responders, Nicholas Groom is used to stress at work.  On the one hand, the stress can be helpful. “I find that when attending a serious incident, it helps me to maintain focus on the situation,” Nicholas Groom said. On the other hand, the work can be highly pressurized. “Too much stress can impair your ability to make decisions,” he adds. And Groom is not alone in his complicated relationship with stress.

2. Many people believe that there should be a balanced amount of stress. In other words, not too much stress so you’re not overwhelmed but not too little stress so you don’t feel unmotivated. After all, some anxiety is motivating; think of the adrenaline before a deadline or the excitement before a competition.  Sports fans sometimes even talk about a “gene” in some athletes who seem to play best in the decisive final moments of a match. Furthermore, many psychologists claim that performance in many situations increases with stress up to a point. Of course, any stress can cause harm when it’s prolonged. To take just one example, a long-term high heart rate is linked to cardiovascular diseases. And additional stressors, such as financial pressures or psychiatric issues, clearly affect how beneficially someone can respond to stress.  

3. So is there a way to harness stress to your advantage while being mindful of its detrimental long-term effects? One key factor is to avoid, whenever possible, the point when stress leads to mental and physical collapse. Crystal Wernicke, 30, has always used stress as a motivator. But juggling between parenting, a full-time job, a voluntary role and financial troubles at the same time became too much and eventually led to a two-month period of illness. Another factor is the presence of control. For those who feel powerless over their situation, stress is unlikely to be beneficial. But with some autonomy over stressful tasks, we are better able to convert that pressure into higher performance.

4. When it comes to stress and how it affects your performance, it’s helpful to recognize the variations in personality, type of stress and task that affect the level of pressure you are under, as well as understanding tools you can use to control and harness that stress. Ultimately, it’s not helpful to take a one-sided view, either demonizing or glorifying stress. As James C Quick, a management professor at the University of Texas, sums up: “Stress can be the kiss of death as well as the spice of life.”
