Consider the following argument.
Premise 1) All unicorns have a single horn.
Premise 2) John is a unicorn.
2a) What is the conclusion?
Correct Answer
B. John has a single horn
Explanation
The conclusion is "John has a single horn" because it directly follows from the given premises. Premise 1 states that all unicorns have a single horn, and Premise 2 states that John is a unicorn. Therefore, it can be concluded that John has a single horn.
2.
Consider the following argument.
Premise 1) All unicorns have a single horn.
Premise 2) John is a unicorn.
Is the argument valid?
Correct Answer
A. Yes
Explanation
The argument is valid because it follows the form of a valid logical syllogism. The first premise states that all unicorns have a single horn, and the second premise states that John is a unicorn. From these premises, it logically follows that John has a single horn. Therefore, the argument is valid.
3.
Consider the following argument.
Premise 1) All unicorns have a single horn.
Premise 2) John is a unicorn.
2c) Is the argument true?
Correct Answer
B. No, true does consider whether or not unicorns actually do exist.
Explanation
The answer is "No, true does consider whether or not unicorns actually do exist" because the argument is based on the assumption that all unicorns have a single horn. However, the existence of unicorns is not established in reality. Therefore, the truth of the argument depends on the factual existence of unicorns, making it necessary to consider whether unicorns actually exist or not.

What is the difference between a true disjunction and a non-true disjunction?
Correct Answer
B. A true disjunction has the only options.
Explanation
A true disjunction refers to a logical statement that presents only two options or alternatives. It implies that one of the options must be true, while the other is false. In contrast, a non-true disjunction may have more than two options or alternatives, which means that more than one option can be true at the same time. Therefore, the correct answer states that a true disjunction has the only options, meaning it presents only two alternatives.

Calling someone names in order to disprove their arguments is called...
Correct Answer
C. Ad hominem
Explanation
Ad hominem is the correct answer because it refers to the act of attacking an opponent's character or personal traits instead of addressing the substance of their arguments. By calling someone names to discredit their arguments, one is engaging in ad hominem fallacy, which is a logical error that distracts from the actual debate and undermines the credibility of the opponent.

When looking at inductive arguments, the conclusion is always 100% knowable. In other words the conclusion follows from the premises 100% of the time
Correct Answer
B. False
Explanation
The explanation for the correct answer "False" is that inductive arguments do not guarantee a 100% knowable conclusion. Inductive reasoning involves making generalizations based on specific observations or evidence, and the conclusion is based on probability rather than certainty. While the premises of an inductive argument may support the conclusion, there is always a possibility of new evidence or counterexamples that could weaken or disprove the conclusion. Therefore, the conclusion of an inductive argument is not always 100% knowable.

What is the following argument type?
If Professor Hull is a genius then he would pass the pop quiz.
Professor Hull did not pass the pop quiz.
Therefore, Professor Hull is not a genius.
Correct Answer
C. Modus Tollens
Explanation
The argument presented follows the pattern of Modus Tollens, which is a valid form of deductive reasoning. Modus Tollens states that if a conditional statement is true and the consequent is false, then the antecedent must also be false. In this case, the conditional statement is "If Professor Hull is a genius then he would pass the pop quiz," and the consequent is "Professor Hull did not pass the pop quiz." Therefore, the argument concludes that "Professor Hull is not a genius." This aligns with the structure of Modus Tollens.
8.
In order to disprove an argument you must...
Correct Answer
B. Give reasons why the evidence does not lead to the conclusion
Explanation
To disprove an argument, it is necessary to provide reasons why the evidence presented does not support the conclusion. By examining and critiquing the evidence, one can demonstrate that it is insufficient, flawed, or does not logically lead to the stated conclusion. This approach challenges the validity and strength of the argument, allowing for a logical refutation.
