Directions: Read the following passage carefully. Each blank in the passage is denoted by a letter. For each blank, five options are provided. Select the most appropriate word from the given options that best fits the respective blank.

Technological advancement and innovation are widely expected to ______________ (A) the productivity levels within an industry. A large portion of academic and policy research ______________ (B) this view as a central premise, particularly from a long-term standpoint. It is also true that the greater the degree of ______________ (C) inefficiency within a system, and the higher the ______________ (D) of resource misallocation, the more sluggish will be the transition toward streamlined and optimised operational processes. Indeed, one can only gain a meaningful understanding of the frequently misread policy dilemmas surrounding ______________ (E) in an emerging industrial economy by first analysing these dynamics at the most fundamental level using available empirical evidence.

Which of the following words best fits the blank marked (B)?

The correct word for blank (B) is upholds.

Step-by-Step Explanation:

1. Analyze the context of the sentence:
The sentence states: "A large portion of academic and policy research ______________ (B) this view as a central premise, particularly from a long-term standpoint."
The blank requires a singular, present-tense main verb to agree with the singular subject "A large portion of academic and policy research" and properly link it to the object "this view".

2. Examine the given options:
• upholds: This is a singular present-tense verb meaning to support, confirm, or maintain. It fits perfectly both grammatically and semantically, as academic research supports/maintains the view as a premise.
• celebrated: This is a past-tense verb and does not match the present-tense flow of the paragraph.
• portion: This is a noun and is grammatically incorrect since a verb is required.
• enhanced: This is a past-tense/participle form that does not logically fit the idea of supporting a view as a central premise.
• magnitude: This is a noun meaning size or extent, making it grammatically incorrect in this position.

3. Conclusion:
Therefore, upholds is the most suitable word to fill blank (B).
