Parents of a Tokyo elementary school are up in arms at being asked to pay 730 dollars for their child's school uniform. A public elementary school in Tokyo's upmarket Ginza district has decided to adopt new school uniforms designed by the luxury Italian designer Armani. The bespoke uniforms, which include a hat and bag, are priced at over 80,000 (730 dollars) each. Parents are angry at the school's decision and are protesting at what they view as the exorbitant price for a uniform of an eight-year-old child. The school said it wanted a designer uniform that represented the rich area of Ginza. School officials visited top department stores and decided to ask the fashion brand Armani to design the uniform.

The expensive uniform has created such a fuss that it has been discussed in Japan's parliament. One lawmaker said that since the school is public and not private, "a certain price range needs to be considered". Finance Minister Taro Aso said. "Clearly it's expensive. It would be tough if a student could not afford to pay for it." Japan's education minister said steps would be taken to ensure the financial burden placed on parents for uniforms, "would not be excessive". Twitter users said young children are not interested in designer clothes. The school principal said. "With humility, I take the criticism that the explanation has been insufficient and not well-timed. I will go on explaining carefully to those concerned."

Read the following passage about the Youth unemployment 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] Youth unemployment has become a pressing issue in Vietnam in recent years, particularly among graduates. [II] As the economy continues to grow, the influx of young people entering the workforce has outpaced the availability of suitable jobs. [III] Various factors contribute to this challenge, leading to significant consequences for both the economy and society. [IV]

    Many factors push young people into unemployment. For instance, a mismatch between education and job market demands often leaves graduates without the skills that employers require. Furthermore, the competitive job market means that even qualified candidates struggle to secure positions. In contrast, there are opportunities that attract youth to urban centers, where industries are more concentrated, providing potential access to better employment prospects and a higher standard of living.

    The impacts of youth unemployment are far-reaching. First, high unemployment rates can lead to increased poverty levels among young adults, which in turn affects their overall well-being and mental health. Additionally, the lack of stable jobs can result in social unrest, as frustrated youth may engage in protests or other forms of activism. Finally, this phenomenon can lead to a brain drain, where skilled young people migrate abroad in search of better opportunities, further depleting the local talent pool.

    Addressing youth unemployment is a complex challenge that requires a comprehensive understanding of its causes and effects. By implementing effective educational programs, fostering entrepreneurship, and encouraging job creation in various sectors, Vietnam can better support its youth, providing them with opportunities for fulfilling careers and contributing to the economy without sacrificing social stability.
