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 practice of manipulating electoral - district boundaries for political gain. It often gives an unfair advantage to one political party. This can lead to that party having a better chance of enacting its platform in state legislatures and the House of Representatives. It does not increase cooperation (so the first and fourth options are wrong), nor does it increase voter turnout or accountability (second option is wrong).

Answer:

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