Question:
A father promised his son that if the son married the daughter of a politician within 18 months, the father would assume responsibility for the son's student loans.
The father was primarily motivated to make this promise by a tax deduction that he thought would be available to him if he paid the son's student loans, although he was also glad to help his son and hoped the son would marry the politician's daughter. The son agreed because he already planned to propose to the politician's daughter, but the father and son never signed a written contract. Fourteen months later, the son married the politician's daughter. The father refused to make any payments on the son's loans, however, because the father had learned that he would not in fact qualify for any tax deductions.
Is the father's oral promise to pay off the son's student loans enforceable?

J) No, because a contract made in consideration of marriage must be in writing.

Choices:
No, because the agreement was conditional on an invalid tax deduction.
Yes, because the contract does not involve the sale of goods.
No, because the son did not provide valid consideration for the father's promise.
Yes, because oral agreements are sufficient in domestic relations.
Yes, because the main purpose doctrine provides an exception to the statute of frauds for surety contracts.
No, because part performance does not apply to student loan forgiveness.
Yes, because the contract could have been, although it was not, fully performed within one year.
No, because the contract allowed for performance extending beyond one year.
Yes, because the father had the intention to fulfill his promise.
No, because a contract made in consideration of marriage must be in writing.

Question: The source of oxygen that drives the internal combustion engine in an automobile is air. Air is a mixture of gases, which are principally $\mathrm{N}_{2} \ ( \sim7 9 \% )$ and $\mathrm{O_{2}} \, (-2 0 \% )$. In the cylinder of an automobile engine, nitrogen can react with oxygen to produce nitric oxide gas, NO. As NO is emitted from the tailpipe of the car, it can react with more oxygen to produce nitrogen dioxide gas.The production of NO$_{x}$ gases is an unwanted side reaction of the main engine combustion process that turns octane, C$_{8}$H$_{18}$, into CO$_{2}$ and water. If 85% of the oxygen in an engine is used to combust octane, and the remainder used to produce nitrogen dioxide, calculate how many grams of nitrogen dioxide would be produced during the combustion of 500 grams of octane.
