Reasoning with “OR” claims

Here is my example:
The family decided it was either going to have a party in their backyard for the last summer celebration or have a bonfire on the beach depending on how warm it was. But because the beach was 30 minutes away and the weather was the coolest it had been all summer, the family decided to have their last summer celebration at home.

By reasoning with “OR”, the argument is valid because there is no way the premise to be true and the conclusion false. The premise was the first sentence about where the party should occur. The conclusion stated that the party would be celebrated in their backyard.

No matter how many “or”s are in the argument, only one may be the right conclusion. A reader must narrow down all the possibilities to get the correct conclusion. By determining which ones are most valid, it makes it easier to find the conclusion.

  1. Hi,
    I like the topic that you chose because not only is it easy to understand, but the example that you gave also clarified how to use the “or” claim further than the book does. The example that you used is also very relatable to real life because we do face situations that require us to choose only one option, by narrowing it down instead of being confused with all the options presented to us. By clarifying how the presence of “or” affects the conclusion of the statement by having a valid argument, it makes the given example more effective. Great work! Keep it up :)
