Question

13 fill in the blank 1 point label whether the conclusion is valid or invalid in the following: all lakes are in canada. lake tahoe is a lake. therefore, lake tahoe is in canada. type your answer...

Explanation:

To determine validity, we check the logical structure. The premise "All Lakes are in Canada" is factually false (e.g., Lake Tahoe is in the US), but logically, if we accept the premise, the conclusion follows. However, since the premise is false, the conclusion is invalid in reality. But in terms of syllogistic logic (assuming premises as given), if we take "All Lakes are in Canada" and "Lake Tahoe is a lake" as true, the conclusion would follow. But since the first premise is empirically false, the conclusion is invalid (as the premise is wrong, the deduction from it, while logically structured, is based on a false premise, making the conclusion invalid in real - world terms).

Answer:

invalid
