Final answer:
The question evaluates the effectiveness of logos in different statements and provides examples to support the assessment.
Step-by-step explanation:
The question is asking whether the use of logos, which is one of the modes of persuasion, is being effective in the given statements. Logos appeals to logic and reason to convince an audience. In the first statement, the reasoning is not logical and convincing as having new jeans is not a valid reason for the speaker needing them. The second and third statements use logical arguments, stating a general truth and drawing a logical conclusion. However, the fourth statement is using an analogy, comparing trying drugs to jumping in front of a train, to argue against trying drugs. The fifth statement presents factual evidence, using statistics about the harmful chemicals in cigarette smoke to argue against starting smoking. Therefore, the second, third, fourth, and fifth statements can be considered as effective use of logos.
