ENGLISHSAT 2021

Interruptions in the supply chain for microchips used in personal electronics have challenged an economist’s assertion that retailers can expect robust growth in sales of those devices in the coming months. The delays are unlikely to ______ her projection entirely but will almost certainly extend its time frame. Which choice completes the text with the most logical and precise word or phrase?

  • A) dispute
  • B) withdraw
  • C) underscore
  • D) invalidate

Correct Answer: D) invalidate

Explanation

The correct choice to complete the text is D) invalidate. The sentence states that interruptions in the supply chain for microchips used in personal electronics have presented a challenge to an economist's assertion about the expected growth in sales of those devices. The missing word or phrase should convey the idea that these interruptions do not completely negate or nullify the economist's projection but rather have an impact on its timeline. Invalidate is the most logical and precise term to fit the context, indicating that the interruptions do not render the projection entirely invalid but do affect its timeframe.
