Sentence 1 Analysis

The first sentence, S1, makes a direct claim: "Bottled water is safer than tap water." This statement implies that tap water carries certain risks or is less safe compared to bottled water.

Sentence 2 Analysis

The second sentence, S2, presents a different scenario: "In many countries tap water is fed to babies." This highlights a common practice where tap water is considered suitable for consumption, even by the most vulnerable group, infants.

Relationship Between S1 and S2

To understand the relationship, let's consider the implications:

• S1 suggests a potential safety concern with tap water.
• S2 points out that tap water is widely used for babies, implying it is considered safe enough for this sensitive population in numerous places.

The practice described in S2 (giving tap water to babies) challenges the broad assertion made in S1 that bottled water is definitively safer. If tap water is routinely given to babies in many countries, it suggests that the safety gap between bottled and tap water might not be as significant as S1 implies, or that tap water is considered safe in many contexts despite S1's claim. Therefore, S2 presents a situation that goes against or differs from the implication of S1.

Selecting the Correct Option

Based on the analysis:

• Option 1 (asserts): S2 does not support or strengthen S1.
• Option 2 (confirms): S2 does not provide evidence that confirms S1.
• Option 3 (contrasts): S2 presents a scenario that differs from and potentially challenges the implication of S1. This fits the relationship observed.
• Option 4 (extension): S2 does not add further detail or develop the idea presented in S1; it introduces a different perspective.

The second sentence highlights a common use of tap water that suggests its safety, which contrasts with the assertion in the first sentence that bottled water is inherently safer.
