Two of the most important mineral resources of early West Africa was gold and salt.
Answer:
<em>Washington, Colorado, Ohio, and Maine are the states that have the most opportunities for voters to have influence on legislation.</em>
Explanation:
The ballot initiatives and popular referendums are shown in purple color, not all the states have it ("all states have ballot initiatives and popular referendums" is not correct) but more than two countries have it so ("Very few states have adopted the initiative and the referendum" is wrong too), because quite a few have it.
Many of the western US states are shown in purple, so most of them do have ballot initiatives and popular referendums ("Most Western states <em>do not have</em> the initiative or the referendum" is not correct).
Washington, Colorado, Ohio and Maine have the same opportunities as the other countries in purple color, then it is correct that "Washington, Colorado, Ohio, and Maine are the states that have the most opportunities for voters to have influence on legislation".
