Difficulty: EasyMulti-Blank Dependency Tracking

Fill in each blank in the passage below with the word that best completes the sentence logically and coherently.

Answer:While the astronomer's early model assumed the planet's atmosphere was completely 【inert】, recent spectroscopic data showed it to be surprisingly 【dynamic】, containing rich trace elements necessary for cloud formation.

Answer

Blank 1: inert (or barren/devoid); Blank 2: dynamic (or complex/active).
The sentence relies on a contrast pivot ('While') comparing early assumptions with recent spectroscopic findings. The final clause describes an atmosphere 'containing rich trace elements necessary for cloud formation,' indicating that the second blank must mean active, complex, or dynamic. Consequently, the first blank must express the opposite quality—inactive, empty, or inert—to complete the contrast accurately.

Step-by-Step Solution

1
Identify the structural transition in the sentence.
The word 'While' at the beginning of the sentence establishes a contrast between the early model and recent spectroscopic findings.
Recognizing structural contrast clues signals that the two blanks must express opposite characteristics.
2
Use trailing contextual clues to deduce the meaning of the second blank.
The descriptive phrase 'containing rich trace elements necessary for cloud formation' indicates that the atmosphere is active and complex.
Contextual elaboration following the second blank defines the positive, active nature required for the second blank.
3
Solve the first blank by applying the contrast relationship.
Since the second blank represents a dynamic or active state, the early model must have assumed the opposite: an inactive, empty, or inert atmosphere.
Inter-blank dependency requires the first blank to complement the second blank across the contrast pivot.

Key Concept

Tracking inter-blank dependencies using contrast pivots and descriptive context clues.
