The completed passage reads:

Vietnamese people used to rely heavily on natural materials for their daily lives and farming tools. Items made from bamboo or wood were common and were often passed down in families. These traditional farming tools helped with planting and harvesting crops. However, modern technology has changed this way of life. Today, farmers use modern machines that make their work easier and faster. Because of these machines, they can grow more food in less time. Moreover, many homes are now built with concrete and bricks instead of wood, which can be stronger but may also harm the environment. Although these changes have improved productivity, they also raise questions about sustainability and the loss of traditional skills.
