Concept

A passage-based completion must preserve the author’s stated degree of relationship instead of importing outside assumptions.

Terms such as no connection, negligible relation, close relation, and occasional dependence express different strengths; the completion must match the passage’s logic.

Application

The passage says that inner balance can be maintained only by establishing harmony with the external environment. The phrase “only by” makes external harmony necessary, so the relationship is close rather than absent, negligible, or occasional.

Contrast

• “has no connection with the external environment” asserts complete independence, which conflicts with the stated need for harmony.

• “is negligibly related to the external environment” reduces the relationship to an almost insignificant influence, weaker than the passage states.

• “is closely related to the external environment” expresses the strong connection implied by maintaining harmony with external conditions.

• “is sometimes dependent on the external environment” makes the link intermittent, whereas the passage presents harmony as the condition for maintaining balance.

Therefore, the completion is “is closely related to the external environment.”
