A student says that if the hypothesis is false, an argument cannot be valid. How do you respond ?
Anton [14]
If a student tells me that an argument that has a false hypothesis cannot be valid, I would reply that we need to look carefully at the meaning of validity in the context of logic.  In everyday speech, we tend to use “valid” to mean the same thing as “true” or “accurate.”  In logic, this is not the way the term is used.

If you need 30 teaspoons of vanilla extract and vanilla is sold in a 4 oz. bottle, how many bottles of vanilla should you buy?
olya-2409 [2.1K]
You would need two bottles, because 4 ounces is the same as 24 teaspoons, so if you buy two bottles for 30 teaspoons you will have 18 teaspoons left (3 ounces) I hope this helps!
