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.

The word "navigating" in paragraph 3 could be best replaced by:

Read the following passage about Huawei company 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.

Huawei is a multinational company that makes  telecommunications  parts for  mobile phones , network equipment  and other high-tech  devices . It is the second largest such company in the world. Huawei has its headquarters  in Shenzhen, which became China’s first special economic zone  in 1979.

The Chinese technology company, which was founded  about 20 years ago, has over 100,000 workers in all parts of the world, more than Microsoft.  Most of the company is owned by its  employees .  Huawei started out in the rural  areas in China. In those days most of the telecom contracts  went to  state-owned  Chinese or  foreign  firms. As the company grew, it took hold of urban markets in big Chinese cities and in 1997 it  expanded to other countries.

Today, Huawei is the second biggest manufacturer of telecom equipment, after Ericsson. In 2011,  annual  sales  is expected to be about $12 billion dollars and  likely to get three times as high within the next ten years. Working for Huawei is something many young Chinese engineers and IT workers dream of. The 1.5 square km site  has modern apartments that can be rented, its own hospital, restaurants and bars where employees  can go to in their free time. For Chinese standards workers are well-paid. Although   Huawei has been concentrating  on making telecom parts and whole networks, the company is also looking into other industries in an  attempt to diversify and grow. At Shenzhen  engineers  are experimenting on new forms of video conferencing, a branch  that is expanding rapidly . The Chinese hi-tech giant  is also starting to produce cloud-based  hardware and computers that work  out of the box . 

Even though Huawei is one of the world leaders in producing mobile phone parts it is also pushing into the consumer market with its own  brand  of computers, tablets and smartphones. So far Huawei has failed  to reach  the American market because of security  reasons. The American  government  thinks it has connections  with the Chinese  military and is afraid it will spy  on the American  public 

The word “expanded” in paragraph 2 is OPPOSITE in meaning to ________.
