Question

widespread gerrymandering can affect both state and national policy by
increasing the number of laws passed each year due to greater cooperation by elected officials at each level.
increasing voter turnout and making elected officials more accountable to the citizens of each state
increasing the chances of one party enacting its platform in state legislatures and the house of representatives
increasing cooperation between state and national governments to pass and enforce similar laws

Explanation:

Gerrymandering is the manipulation of electoral district boundaries to favor one political party. When a party can gerrymander districts effectively, it increases the likelihood of that party winning a majority of seats in legislative bodies (such as state legislatures and the U.S. House of Representatives). With a majority, the party has a better chance of enacting its policy platform.

• The first option is incorrect because gerrymandering is about partisan advantage, not cooperation to pass more laws.
• The second option is wrong as gerrymandering often suppresses fair representation rather than increasing voter - turnout or accountability (in a positive, democratic sense). For example, it can create "safe" seats where one party has little incentive to be accountable to a broad range of voters.
• The fourth option is incorrect because gerrymandering is a partisan tactic within a legislative body (to gain a majority) rather than a tool for inter - governmental (state - national) cooperation.

Answer:

Increasing the chances of one party enacting its platform in state legislatures and the House of Representatives.
