Answer:
Lawmakers could prevent the Chinese and Hawaiian people of Oregon from participating in the elections by establishing a law, where only European and American citizens had the right to vote.
Step-by-step explanation:
Oregon's white and racist lawmakers were aware that the population of the Chinese and Hawaiian population was very large in Oregon. these legislators considered Chinese and Hawaiian culture to be inferior and lacking in political and democratic concepts. Because of this prejudice, they did not want this portion of the population to have an influence on American political issues. However, they believed that European citizens and heterogeneously white people, had a cultural value equal to the American value and, therefore, their participation in Oregon politics was welcome.
To prevent Chinese and Hawaiian citizens from voting, lawmakers could formulate a law that allowed only Americans and Europeans resident in Oregon to participate in these elections.
