Complete the passage below by filling in each blank with the word that best fits the context established by the contrast structural signals.
Answer:Far from revealing a paleoclimate trajectory that was essentially 【equable】, the dendrochronological record exhibits extreme, centuries-long thermal shifts; paradoxically, however, this erratic volatility has served not to 【discredit】 established climate models, but rather to 【buttress】 them by revealing hitherto unrecognized buffering mechanisms within high-latitude forest ecosystems.
Answer
The first blank requires a word denoting climate stability or uniformity (such as 'equable'), contrasting with 'extreme, centuries-long thermal shifts' via the reversal pivot 'Far from'. The second blank requires a verb meaning to disallow or weaken (such as 'discredit'), while the third blank requires a contrasting verb meaning to strengthen or support (such as 'buttress'), driven by the complex contrast signal 'paradoxically, however' and the 'not to [X], but rather to [Y]' construction.
The correct words satisfy all structural contrast signals in the sentence. The phrase 'Far from' requires the first blank to contrast with 'extreme, centuries-long thermal shifts', making a word meaning stable or mild ('equable') necessary. Next, 'paradoxically, however' signals that the expected negative effect of volatility does not occur; thus, the volatility does 'not discredit' (blank 2) the models, 'but rather buttresses' (blank 3) them by demonstrating their validity when accounting for newly discovered ecological buffering mechanisms.
Step-by-Step Solution
Key Concept
Decoding multi-blank Text Completion passages by identifying compound contrast signals ('far from', 'paradoxically, however', 'not... but rather') to map semantic reversals across connected blanks.
