Answer: Whether the lower-court ruling in the case conflicts with an earlier Supreme Court ruling.
Step-by-step explanation:
The Supreme court is referred to as the highest court that is within a legal jurisdiction. The factor that the Supreme Court generally consider especially important when deciding which cases to review is whether the lower-court ruling in the case conflicts with an earlier Supreme Court ruling.
This is because when a decision is made by the Supreme court, it isn't reviewed further. In such cases, if it has been reviewed by the Supreme Court earlier, it won't be reviewes anymore.
Other options given are incorrect. Whether the case originated in the state or federal court system, or whether it involves the federal government employees isn't a factor that's considered by the Supreme Court.
