Read the following passage about endangered languages and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questionsfrom 23 to 30.

The Koromi trend has taken social media by storm, influencing fashion, lifestyle, and online communities worldwide. Originating in Japan, Koromi is characterized by a unique blend of gothic aesthetics, cute elements, and bold self-expression. Unlike mainstream kawaii culture, which emphasizes bright colors and cheerful themes, Koromi embraces darker shades, punk influences, and a rebellious attitude. This fusion of edginess and playfulness has resonated with many young people looking for an alternative form of self-representation.

Social media platforms like TikTok and Instagram have played a crucial role in popularizing the trend, as influencers and fashion enthusiasts share their interpretations of the Koromi style. The trend's rise is also linked to a growing appreciation for individuality and alternative fashion in contemporary youth culture.

Beyond fashion, the Koromi trend has influenced makeup styles, accessories, and even music preferences. Many followers of this aesthetic incorporate dark eyeliner, edgy clothing, and playful accessories to create a distinctive look. As more people adopt the Koromi lifestyle, brands have started releasing special collections inspired by the trend. However, some critics argue that the commercial adoption of Koromi dilutes its original meaning and turns it into a passing fad rather than a genuine subculture.

While Koromi's popularity continues to grow, it remains a niche trend compared to mainstream fashion movements. Its impact, however, is undeniable, as it encourages self-expression and challenges conventional beauty standards. Whether it will evolve into a long-lasting cultural phenomenon or fade away as another internet-driven craze remains to be seen.
