Read the passage and answer the following question:
The Halloween celebration originated from an ancient Celtic festival some 2,000 years ago in the area that is now Ireland. It came to America during colonization and the American version of Halloween emerged as the result of different European and Native American beliefs and customs being mashed-up. By the beginning of the twentieth century, Halloween became a holiday for community and neighborly gathering, and Halloween parties for both children and adults became the most common way to celebrate the day.
