Exercise 1: Analyzing Arguments

Read the following argument and determine whether it is valid or invalid. Provide a brief explanation to support your answer.

Argument: “All cats have fur. Fluffy is a cat. Therefore, Fluffy has fur.”

Answer: Valid. The argument follows the logical structure of a categorical syllogism, where the conclusion logically follows from the premises.

Exercise 2: Identifying Assumptions

Identify the underlying assumptions in the following scenario and explain why they are important to consider.

Scenario: “John is always late to work. Therefore, he must be lazy.”

Answer: Assumption: Being late to work is solely due to laziness. It’s important to consider assumptions because they can influence our interpretations and conclusions, leading to potential biases or inaccuracies.

Exercise 3: Evaluating Evidence

Evaluate the credibility of the following evidence and explain your reasoning.

Evidence: “According to a survey conducted by XYZ Research, 90% of participants prefer Product A over Product B.”

Answer: The evidence appears credible as it cites a specific source (XYZ Research) and provides quantitative data (90% preference). However, it’s important to consider factors such as sample size, methodology, and potential biases in the survey.

Exercise 4: Problem-Solving

Solve the following problem and explain your approach to reaching the solution.

Problem: “A train leaves Station A traveling at 60 mph. Another train leaves Station B traveling at 75 mph. If Station B is 150 miles away from Station A, how long will it take for the trains to meet?“

Answer: To solve this problem, we can use the formula Distance = Rate × Time. Let t be the time it takes for the trains to meet. For Train A, the distance traveled is 60t, and for Train B, the distance traveled is 75t. Since the total distance is 150 miles, we have the equation 60t + 75t = 150. Solving for t, we get t = 2 hours.

Exercise 5: Drawing Conclusions

Draw a logical conclusion based on the information provided in the following scenario.

Scenario: “All mammals are warm-blooded. Dogs are warm-blooded animals. Therefore, dogs are mammals.”

Answer: The conclusion is logically valid as it follows the principle of categorical syllogism, where the conclusion follows logically from the premises.
