Answer:
The correct is D. He wanted to avoid having the congressional map challenged in court.
Explanation:
Governor Lee Cruce clashed with the Democratic Party on several policies, including higher education and local interest projects. Another one of their differences was the plan to gerrymander Oklahoma in 1912.
Cruce was opposed to gerrymandering Oklahoma as he wished to avoid having the congressional map challenged in court. As per the rules of the Supreme Court, four among the nine Justices had to vote to accept a case. Lee's veto of the gerrymandering plan angered many of the Democrats and eventually contributed to his break with the Democratic Party.

Activation of the <u>Serotonin </u>neurons of the forebrain would be expected to <u>suppress </u>aggressive attack.
Numerous studies link elevated impulsive and aggressive behaviors with reduced serotonin metabolites. The opposing association has been substantiated by therapies targeted at directly reducing serotonin cell activity, despite the fact that pharmaceutical reduction of serotonin is linked to an increase in aggression.
Furthermore, it is unclear whether any of the relationships observed may be caused by changed serotonin activity during development. Here, we used two Pharmacogenetic techniques to selectively and reversibly decrease the firing of serotonin neurons in behaving animals in transgenic mice.
A persistent reduction in serotonin neuron firing was linked to increased aggression, as demonstrated by conditional over expression of the serotonin 1A receptor (Htr1a) in serotonin neurons.
