For something to be an argument it has to have a premise that supports a conclusion.

In the example he gave, we were identifying if it was an argument and if so, what was the premise and conclusion.

For example:

1. "Premise: Not every mammal is suitable to keep as a pet.

2. Conclusion: Tigers are very aggressive and can cause serious injuries to people."

In this example the Premise DOES NOT support the conclusion. BUT we can still look at the statements in the reverse order:

For example:

1. "Premise: Tigers are very aggressive and can cause serious injuries to people.

2. Conclusion: Not every mammal is suitable to keep as a pet."

In this example the Premise DOES support the conclusion. THEREFORE THIS IS AN ARGUMENT.

This also means that the way we have labeled each claim in this second example is correct. Tigers being aggressive is the premise and not all mammals being suitable pets is the conclusion. "If it's true that tigers are aggressive and can hurt people, then it is more likely true that not all mammals make good pets."

Hope this helps!! 💕💕
