Answer:
Human beings might coexist with the natural world if they protect the nature by minimum use of products which disturb the nature.
Explanation:
There is a great relationship between human and nature. Human cannot live without nature. Nature provides water for drinking, food and other necessity of life. If we save nature we stop species extinction because there are millions of species present in the natural ecosystem. If we disturb the nature by burning of fossil fuels and cutting of trees, many species lost their habitat and the whole ecosystem is disturbed. So far maintaining balance in the nature, the human must take some serious steps such as protect water bodies from harmful substances and grow more trees etc.
Strangely enough the correct answer here would be actually D as the voting ballots before the 1890s were in fact printed by the political parties themselves. Today the printing of ballots is a very serious business and there are strict regulations and control mechanisms in place in order to stop voter fraud which unfortunately is a big issue.
