Question 15

Explanation

Let's analyze the logic of the text using the principle of implication.

The first statement provides a cause-and-effect rule: "A person can catch the flu if they inhale saliva droplets from a patient." We can simplify this to:

If inhale droplets ($P$) $\rightarrow$ Catch the flu ($Q$).

The fact is that Nia accidentally inhaled cough droplets from a person with the flu. This means condition $P$ is met. Based on the logic rule of Modus Ponens, if condition $P$ occurs, then the consequence $Q$ (catching the flu) should occur.

However, the proposed conclusion states the opposite, namely "Nia will not catch the flu". This statement directly contradicts the valid deduction derived from the premises. Since the conclusion denies the logical consequence that should happen, the quality of the conclusion is definitely false.
