Read the following passage about Vietnamese cultural identity 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.

Vietnamese cultural identity is a rich and intricate tapestry that reflects the nation's long and storied history. Rooted in over a thousand years of civilization, Vietnam's cultural identity is a fusion of indigenous traditions and external influences, shaped by its geographical location and historical interactions.

First and foremost, at the heart of Vietnamese culture is a deep reverence for family and community. Confucian values emphasizing respect for elders, filial piety, and social harmony have played a pivotal role in shaping Vietnamese society. These values are reflected in the close-knit family structures, hierarchical relationships, and communal rituals that are integral to daily life.

Secondly, Vietnamese cuisine is celebrated worldwide for its exquisite flavors and diversity. With its emphasis on fresh ingredients, fragrant herbs, and balanced flavors, Vietnamese food tells a story of the country's agricultural heritage and regional variations. Iconic dishes like pho, banh mi, and spring rolls have become global favorites, representing the culinary artistry deeply ingrained in Vietnamese culture. Also, Vietnam's artistic expressions are equally captivating. Traditional art forms like water puppetry, silk painting, and folk music continue to thrive alongside contemporary artistic movements. Ao dai, a graceful traditional dress, exemplifies the fusion of elegance and modesty in Vietnamese fashion, symbolizing cultural pride and identity.

Today, in the face of modernization and globalization, Vietnamese cultural identity remains resilient. While adapting to the challenges of the 21st century, the Vietnamese people continue to honor their traditions, celebrate their unique cultural expressions, and pass on their heritage to future generations, ensuring that their cultural identity remains vibrant and enduring.

Read the following passage about education in Nepal 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. 

Fashion in the 1960s reflected the cultural and political upheaval of the time. The hippie and counterculture movement gave rise to accessories like Pocahontas-style headbands and medallions worn around the neck. Hippies wore long, loosely fitting clothing, often in natural fabrics. Hemlines rose as Mary Quant popularized the miniskirt and hot pants in her lines for JC Penney. And mod fashion, with brightly colored space-age geometric patterns, shift dresses and colored tights became the mainstream. Both miniskirts and mod-shift dresses were worn with knee-high go-go boots.

[A] During the 1970s, the loose-fitting hippie clothes of the prior decade gave way to exotic fabrics and bell-bottom jeans for men and women. Hemlines continued to rise and hot pants continued their popularity, reflecting the flashy style of the decade. However, the 1970s also saw the popularity of a longer hemline, from mid-calf to ankle-length. [B] Women wore peasant-style clothing, especially blouses with off-the-shoulder necklines and lace trim, with their jeans or skirts. [C] Disco fashion emerged, featuring bright patterns and tightly fitting clothing meant to show off the body. Platform shoes elevated their wearer, male or female, anywhere from two to four inches or more. [D]

The 1980s saw another fashion upheaval. Angst-ridden punks wore Dr. Marten and steel-toed army boots, chains, tartan patterns, and bondage pants. Punks focused more on their hair during this period, dying, teasing and chopping their hair into asymmetric styles that seemed to defy gravity. Women—and men—experimented with heavy eyeliner in a variety of colors. Women wore neon colors, jelly shoes, tight jeans, leggings, leg warmers and oversized sweatshirts. Menswear-inspired looks also became popular for both sexes. Men wore ‘power suits,’ named so for their price, which made these suits a reflection of the wealth of the wearer. Women’s jackets featured big shoulder pads that made the shoulders appear higher and larger, similar to the male silhouette.

1990’s fashion was far more subdued than the garish, wild styles of the 1980s. Bands like Nirvana influenced the grunge look, which featured rock-concert tee shirts under plaid flannel shirts, jeans and long, greasy hair. Overalls were worn by both sexes, either with one or both shoulder straps unhooked. The punk style of the 1870s and 1980s evolved into the goth fashion trend, which featured black clothing, black boots and studded bracelets in the style of bands like Nine Inch Nails and Marilyn Manson.
