Read the following passage about Traveling 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.

          Traveling and exploring new places is an exciting way to experience different cultures and expand one’s horizons. Whether it’s a short trip to a neighbouring town or a long journey to a foreign country, stepping out into the world offers numerous benefits. It allows individuals to gain new perspectives, meet diverse people, and create lasting memories. Additionally, traveling can enhance personal growth and provide a sense of adventure and fulfillment.

          One of the key advantages of traveling is the opportunity to learn about different cultures. By immersing oneself in a new environment, travellers can gain a deeper understanding of local customs, traditions, and lifestyles. This cultural exchange fosters mutual respect and appreciation among people from different backgrounds. Moreover, experiencing different cultures can challenge preconceptions and broaden one’s worldview.

          Traveling also promotes personal development. Facing unfamiliar situations and overcoming challenges can boost confidence and adaptability. Travelers often find themselves  navigating new cities, trying unfamiliar foods, and communicating in foreign languages. These experiences can enhance problem-solving skills and resilience. Furthermore, the sense of accomplishment from successfully managing a trip can lead to increased self-esteem and a greater sense of independence.

          Another benefit of traveling is the chance to disconnect from the routine of everyday life. Exploring new places provides a break from the usual responsibilities and stresses. This can be refreshing and rejuvenating, allowing individuals to return home with a renewed sense of energy and perspective. Travel can also foster creativity by exposing individuals to new sights, sounds, and ideas.

          Despite its benefits, traveling can also present challenges. Planning a trip requires time and effort, and unexpected situations can arise. However, these challenges can be viewed as opportunities for growth and learning. With careful planning and a positive mindset, the rewards of traveling far outweigh the difficulties.

Which of the following best paraphrases the underlined sentence in paragraph 4? 

Đâu là ý đúng: Bào quan dạng bong bóng trong tế bào chất của tế bào động thực vật là gì?

Read the passage below and choose A, B, C or D.

Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a by-product of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it.

Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection. Noise causes effects that the hearer cannot control and to which the body never becomes  accustomed. Loud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased.

Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America's number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each other.

Read the passage and do the tasks below. Decide whether the following statements are True (T), False (F) or Not Given (NG).

Most people relate stress to physical symptoms like an upset stomach or headaches. Research has suggested that negative emotions and thoughts may also have close links to our brain. Researchers have started finding out why we tend to remember negative things more strongly and, in more detail, than good ones. “The hrain handles positive and negative information in different parts. Negative emotions involve more thinking, and the information is processed more thoroughly. Thus, we tend to ruminate more about unpleasant events and use stronger words to describe them than happy ones," said Clifford Nass, a professor at Stanford University.

Rick Hanson also shares the idea that our minds naturally focus on the bad and discard the good. He stated, "negative stimuli produce more neural activity than do equally intense positive ones. They are also perceived more easily and quickly." This was obtained from his little experiment in which twenty people were asked to look at pictures showing anger or happiness. The participants could identify angry faces faster than happy ones even if it was so quickly.

In a journal article Baumeister co-authored in 2001, "Bad is Stronger Than Good", he concluded, "bad emotions, bad parents and bad feedback have more impact than good ones." This is "a basic and wide-ranging principle of psychology". Thus, Baumeister and his colleagues noted that bad incidents, such as losing your dreamy job and breaking up with your girlfriend or boyfriend, may have a greater impact than landing a job or receiving a marriage proposal.
