## Exercise 15

### Question

export const metadata = {
  title: "Question 15",
  authors: [{ name: "Nabil Akbarazzima Fatih" }],
  date: "01/29/2026",
};

Every student in class A can sing, and some even have very melodious voices. Students who have very melodious voices are definitely good at playing the guitar. Armin is a student who is good at playing the guitar.

The conclusion based on this information is that Armin is a student who has a very melodious voice and is good at playing many musical instruments.

Which of the following statements describes the quality of this conclusion?


### Choices

- [ ] The conclusion is definitely true
- [ ] The conclusion is possibly true
- [ ] The conclusion is definitely false
- [x] The conclusion is irrelevant to the information provided
- [ ] The conclusion cannot be evaluated because the information is insufficient

### Answer & Explanation

export const metadata = {

};

To evaluate the quality of the conclusion, we must compare its content with the premises available in the text.

The proposed conclusion makes two claims about Armin:
1.  **Has a very melodious voice**: Based on the logic "Melodious voice <InlineMath math="\to" /> Good at guitar", the fact that Armin is good at playing guitar does not automatically mean he has a melodious voice (he could be good at guitar but have an ordinary voice). So, this part is only *possibly true*.
2.  **Good at playing many musical instruments**: The text only mentions the ability to play the **guitar**. There is absolutely no information regarding other musical instruments or the ability to play "many" instruments.

This second claim ("many musical instruments") introduces new information that is not discussed at all in the premises. Since the conclusion contains information that has no basis or connection to the provided text, the conclusion is considered **irrelevant**.

We cannot evaluate the truth or falsity of Armin's ability to play other instruments because that information is absent from the context (the question text).

Therefore, the statement that best describes the conclusion is that it is irrelevant to the information provided.

> The conclusion is irrelevant to the information provided
