Vietnamese Women’s Achievements

Women have always played an important role in Vietnam’s history. Some fight for their country, some inspire others, and some make positive changes to society. Their contributions have shaped the nation in various ways, leaving a lasting impact on culture, politics, and the arts.

Trưng Trắc and Trưng Nhị are famous examples of women who fought for their country’s freedom. Known in Vietnamese as “Hai Bà Trưng,” the Trưng sisters successfully led their people in a rebellion against foreign invaders in 40 A.D. After their victory, they ruled the country for three years, demonstrating remarkable leadership and bravery. As the first female rulers of Vietnam, the Trưng sisters have become symbols of patriotism and resilience. Their significance is even greater considering that Vietnamese women at the time had very limited access to education and politics. Their story continues to inspire generations.

Sương Nguyệt Anh is another example of an influential Vietnamese woman. As the daughter of the patriotic poet Nguyễn Đình Chiểu, she mastered literature from a young age. She worked as a teacher before becoming the editor-in-chief of Nữ Giới Chung, the first women’s newspaper in Sài Gòn, in 1918. As the first female editor in Vietnam, she made significant contributions to the press, feminism, and poetry. Through her work, she promoted women’s rights and encouraged female empowerment.

A third example is Điềm Phùng Thị. She graduated from Hà Nội Medical University in 1946 and earned a PhD in dentistry in France in 1954. However, she later pursued a career in sculpture, creating artworks that reflected her love for Vietnam. She exhibited her work throughout Europe and became the first female Vietnamese member of the European Academy of Arts and Sciences in 1992. Her name was later recorded in the Larousse Dictionary of Painters, recognizing her as a remarkable artist.

Which of the following is NOT mentioned as one of the important roles of Vietnamese women in the passage?

Read the following passage about news 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.

[I] Wildlife conservation refers to the efforts made to protect and preserve wild animal species and their habitats. [II] It is crucial for maintaining biodiversity, which plays a vital role in ecosystem stability and health (Smith & Jones, 2018). [III] Unfortunately, many species are threatened due to habitat destruction, poaching, and climate change, making conservation efforts more urgent than ever. [IV]

One of the primary reasons for wildlife conservation is the preservation of biodiversity. A diverse range of species contributes to ecosystem services, such as pollination, water purification, and climate regulation. The loss of a single species can disrupt these services and lead to ecological imbalances. For instance, the decline of pollinators like bees has serious implications for food production and agriculture (Global Biodiversity Outlook, 2020).

Moreover, wildlife conservation has significant economic benefits. Many communities depend on ecotourism, which relies on healthy wildlife populations and intact ecosystems. According to a study by the World Wildlife Fund (WWF), ecotourism can generate billions of dollars in revenue, providing jobs and supporting local economies (WWF, 2021). Protecting wildlife not only safeguards natural resources but also creates sustainable livelihoods for local populations.

However, effective wildlife conservation requires a collaborative approach. Governments, non-governmental organizations, and local communities must work together to implement policies and strategies that promote conservation efforts. Community-based conservation initiatives, where local people actively participate in protecting their natural resources, have shown promising results. These initiatives empower communities and ensure that conservation efforts are tailored to local needs and contexts (Bennett & Dearden, 2014).

Where in paragraph I does the following sentence best fit?

Conservation measures are essential for the survival of many endangered species.

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

[I] A newborn baby can see, hear and feel. By the age of five, a child can talk, ride a bike and invent imaginary friends. How does this development happen? [II]We don't understand the way language, thinking and planning develop very well. [III]Now scientists are using new technology to ‘see’ into children's brains. And they are discovering new information about the way a baby's brain develops. [IV]

A study in 2010 showed that children who were afforded more focus often gained an edge in IQ. The brain of a newborn infant contains nearly a hundred billion neurons. This number is comparable to that of an adult's brain. As they mature, an infant assimilates information through the sensory modalities of sight, hearing, smell, taste, and touch. This information fosters intricate connections between different regions of the brain. By the age of three, there are approximately a hundred trillion synaptic connections.

One experiment looked at images of babies' brains while they were listening to different sounds. The sounds were in different sequences. For example, one sequence was mu-ba-ba. This is the pattern ‘A-B-B’. Another sequence was mu-ba-ge. This is the pattern ‘A-B-C’. The images showed that the part of the brain responsible for speech was more active during ‘A-B-B’ patterns. This shows that babies can tell the difference between different patterns. This experiment is interesting because sequences of words are important to grammar and meaning. Compare two sentences with the same words in a different order: ‘John killed the bear’ is very different from ‘The bear killed John.’ So babies are starting to learn grammatical rules from the beginning of life.

Researchers also know that babies need to hear a lot of language in order to understand grammar rules. But there is a big difference between listening to television, audiobooks or the internet, and interacting with people. One study compared two groups of nine-month-old American babies. One group watched videos of Mandarin Chinese sounds. In the other group, people spoke the same sounds to the babies. The test results showed that the second group could recognize different sounds, however, the first group learned nothing. The scientist, Patricia Kuhl, said this result was very surprising. It suggests that social experience is essential to successful brain development in babies.

Which of the following best paraphrases the sentence in paragraph 4:

"Social experience is essential to successful brain development in babies."
