Consider the following text "Our agreement states that either no crashes will occur in 2018’s first quarter or the average response time of requests is under an hour. If the agreement is broken, you will pay $8000 in damages. As shown in these records, the average response time is over two hours. You have paid us $8000. I can only conclude that a crash, or multiple crashes, have occurred."
Represent the propositions and the conclusion, clearly labeling propositional atoms (e.g., what is p?). Prove the argument or show that it is incorrect.

Expert Solution

A proposition or statement is a sentence which is either true or false while a conclusion is derived from these propositions.

Here, agreement states that:

Let proposition P: No crashes will occur in 2018’s first quarter

Let proposition Q: The average response time of requests is under an hour

If either P or Q is false, the agreement is broken and you need to pay $8000.

Since, it is given that the average response time is over two hours, i.e., Q is false, the agreement is broken and you need to pay $8000.

Here, conclusion is: a crash, or multiple crashes, have occurred (i.e., P is false).

Clearly the conclusion is invalid since the average response time is over two hours (i.e. Q is false) but we can not say that at least one crash has happened (i.e. we can't say that P is false).

Our textbook states: "As a general rule, an agreement without consideration will not be an enforceable contract, because consideration is so important as the binding element within a contractual relationship." Research and explain why this is so. In so doing, define and discuss the concept of consideration, including within your discussion the distinction between adequacy of consideration and sufficiency of consideration. This is an open ended question, so just need to answer it with supporting information and why you think...

NAFTA is a multilateral trade agreement between Canada, United States, and Mexico enacted in the 1990's. This agreement eliminates trade barriers between these countries and allows trade to move freely without tariffs or restrictions. However, there is a downside to this. Look at "in the News" on pg. 782 of the text on jobs relating to NAFTA. How do agricultural workers feel about this agreement? How about construction workers?
