Wrong options:

• about: 'About' suggests a topic or subject matter, which does not fit the context of possession in this sentence.
• to: 'To' indicates direction or purpose, which is not appropriate here as it does not convey the idea of possession.
• for: 'For' implies a purpose or benefit, which does not align with the context of preservation of culture.

Correct answer: banned

Explanation: The verb 'banned' appropriately conveys the action of prohibiting something, fitting grammatically and contextually as it describes the restriction of internet, television, and western dress in Bhutan.

Meaning: 'Banned' means to officially or legally prohibit something, indicating that these items were not allowed in the country.

Wrong options:

• summoned: 'Summoned' means to call upon or order someone to be present, which does not fit the context of prohibiting items.
• observed: 'Observed' means to watch or notice something, which does not convey the idea of prohibition required in this context.
• displayed: 'Displayed' means to show or exhibit something, which is the opposite of banning.

Correct answer: statistically

Explanation: The adverb 'statistically' fits well as it relates to data and measurements, aligning with the context of GNH being a term based on statistical analysis.

Meaning: 'Statistically' refers to something that is related to the collection and analysis of data, indicating that GNH is based on measurable factors.

Wrong options:

• barely: 'Barely' means only just or hardly, which does not fit the context of describing a term based on data.
• overwhelmingly: 'Overwhelmingly' suggests a strong or dominant degree, which does not accurately describe the nature of GNH as a statistical term.
• roughly: 'Roughly' means approximately or not exactly, which does not convey the precise nature of statistical measurement.

Correct answer: maintaining

Explanation: The gerund 'maintaining' fits grammatically as it describes the ongoing action of keeping something intact, which aligns with the context of preserving the environment and cultural identity while growing economically.

Meaning: 'Maintaining' means to keep something in a particular state or condition, indicating that Bhutan is actively preserving its environment and culture.

Wrong options:

• demeaning: 'Demeaning' means causing a loss of respect, which does not fit the positive context of preserving identity and environment.
• intruding: 'Intruding' means to enter without permission, which does not align with the idea of preserving or maintaining something.
