1. Which of the following statements is best describes joint and several liability?
A Plaintiff can obtain a judgment against two defendants who are both 50% liable and collect the full amount of the judgment from each defendant.

A Because reasonableness is a question of fact, the jury always decides this issue.
B Because reasonableness is a question of fact, the jury always decides this issue, subject to the judge’s right to make the ultimate decision.
C Because reasonableness is a question of law, the judge always decides this issue.
D The “fixed standard of reasonableness” approach is now a firmly established legal principle.

A “Well established custom” is not an appropriate test to use.
B custom is not a well-received principle to show breach of duty.
C Custom does not relate to the consideration of the risk calculus.

4. Based on your reading of the Pipher v. Parsell case, which statement does not represent any of the legal principles of breach of duty considered by the court?
A If actions of a passenger that cause an accident are not foreseeable, negligence is still attributed to the driver.
B Negligence is conduct that creates an unreasonable risk.
C One main component of determining foreseeable risk was whether a reasonable person would foresee that harm might result from his actions.
D Proof of negligent conduct may require examination of the defendant’s conduct and any alternate conduct the defendant should have engaged in to avoid the injury caused.
