Questions & Step-by-Step Solutions
Some cars are red. All red things are fast. Therefore, some cars are fast. Is this conclusion valid? (2023)
Step 1: Identify the first statement: 'Some cars are red.' This means there are at least a few cars that are red.
Step 2: Identify the second statement: 'All red things are fast.' This means everything that is red is also fast.
Step 3: Combine the information: Since some cars are red (from Step 1) and all red things are fast (from Step 2), it means those red cars must also be fast.
Step 4: Conclusion: Therefore, it is valid to say that some cars are fast because the red cars are included in the group of fast things.
