Read the following passage about climate change 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 31 to 40.

           Climate change refers to the long-term alteration of temperature and typical weather patterns in a place. This phenomenon is largely driven by human activities, particularly the burning of fossil fuels such as coal, oil, and gas, which increase the concentration of greenhouse gases in the atmosphere. They trap heat from the sun, leading to global warming and causing severe weather events, such as hurricanes, floods, and droughts, to become more frequent and intense. Climate change impacts nearly every region of the world and affects the natural environment, economies, and human health.

           As temperatures rise, polar ice caps and glaciers are melting at alarming rates, contributing to rising sea levels. Coastal regions face an increased risk of flooding, and many low-lying islands are at risk of disappearing entirely. Additionally, higher temperatures lead to the warming of oceans, affecting marine ecosystems and causing coral bleaching, which threatens biodiversity and the livelihoods of millions of people who depend on fishing.

            [I] The consequences of climate change are not just environmental; they also affect human society in significant ways. [II] Changes in weather patterns disrupt agriculture, leading to crop failures and food shortages in vulnerable regions. [III] Furthermore, climate change is linked to health issues such as respiratory diseases, heat strokes, and the spread of diseases carried by insects, like malaria and dengue fever. [IV]

           To combat climate change, a coordinated global effort is necessary. Governments, organizations, and individuals all have roles to play in reducing greenhouse gas emissions and promoting sustainable practices. Shifting to renewable energy sources, such as wind, solar, and hydropower, is essential. Additionally, conserving forests and investing in technology that captures carbon dioxide from the atmosphere can help mitigate the effects of climate change and pave the way for a healthier planet.

The phrase "pave the way for" in paragraph 4 could best be replaced by ________.

Read the following passage 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.

The 22nd Southeast Asian Games were held in Vietnam from December 5th to 13th, 2003. It marked the first time Vietnam hosted such a significant sporting event, yet the Games were a great success. They became a grand festival that impressed sports enthusiasts with their spirit of solidarity, cooperation for peace, and development. The event demonstrated Vietnam's capability to unite the region through sports.

Athletes from 11 participating countries competed in 32 sports, winning a total of 444 gold medals. Teams in table tennis, badminton, karate, volleyball, basketball, and wrestling showcased some of the region’s top competitors. Notably, many records set during the Games were close to international standards. Vietnam emerged victorious, securing 158 gold medals and finishing at the top of the medal standings. Thailand came second with 90 golds, while Indonesia ranked third with 55. Singapore and Vietnam were the only nations with participants honored as the Most Outstanding Athletes in Swimming and Shooting events.

In football, the Vietnamese Women's Football team successfully defended their SEA Games title, a moment of pride for the host nation. In the Men's Football Final, Vietnam faced Thailand but lost, with the Thai team taking home the gold medal. Other sports, such as karate, athletics, bodybuilding, and wushu, saw young and talented Vietnamese athletes delivering exceptional performances and securing numerous gold medals. The strong performance of the athletes reflected Vietnam's growing prowess in the regional sports arena.

Vietnam’s first-place finish was not surprising. To prepare for the 22nd SEA Games, the country implemented an intensive training program for its athletes, involving both domestic and international facilities. Furthermore, the enthusiastic support from the Vietnamese people inspired the athletes to compete in high spirits. This success solidified Vietnam’s reputation as an excellent host for international sporting events. With this achievement, Vietnam has demonstrated its potential to host even larger competitions, such as the Asian Games, in the future.

Which of the following is NOT mentioned as one of the sports that Vietnam won gold medals in?
