Meaning: 'Implemented' means to put a plan or idea into action or effect, referring to how superintelligence can be realized in various forms.

Wrong options:

• popular: 'Popular' refers to being well-liked or widely accepted, which does not fit the context of how superintelligence is established or realized.
• working: 'Working' implies functioning or operating, but it does not convey the sense of actual establishment or realization as required in this context.
• evaluated: 'Evaluated' means assessed or judged, which does not align with the context of how superintelligence is created or put into practice.

Correct answer: to

Explanation: The preposition 'to' is used to indicate comparison, which is necessary in this context to show the relationship between Deep Blue and the best humans. It correctly follows the comparative structure of the sentence, indicating a standard of comparison.

Meaning: 'To' in this context indicates a comparison, suggesting that Deep Blue is not vastly superior when compared to the best human players.

Wrong options:

• than: 'Than' is typically used in comparative structures but does not fit grammatically here as it would require a different sentence structure.
• then: 'Then' refers to time and does not fit the context of comparison being made in this sentence.
• on: 'On' does not convey the necessary comparative relationship and is not appropriate in this context.

Correct answer: of

Explanation: The preposition 'of' is used to indicate belonging or association, which fits well in this context to describe the intellectual feats that are characteristic of corporations or the scientific community. It correctly links the feats to the entities being discussed.

Meaning: 'Of' indicates that the intellectual feats belong to or are associated with the entities mentioned, emphasizing their capabilities.

Wrong options:

• for: 'For' suggests purpose or benefit, which does not fit the context of describing the feats associated with the entities.
• to: 'To' implies direction or relationship but does not convey the sense of belonging or association needed here.
• so: 'So' is used to indicate a consequence or result, which does not fit the context of describing the feats.

Correct answer: sufficiently

Explanation: The adverb 'sufficiently' modifies the adjective 'integrated', indicating the degree to which the entities are integrated. It fits grammatically and contextually, as it describes the level of integration required to be considered an intellect.

Meaning: 'Sufficiently' means to an adequate degree, indicating that the integration of these entities is not enough to classify them as intellects.

Wrong options:

• suffice: 'Suffice' is a verb meaning to be enough, which does not fit grammatically as it cannot modify 'integrated'.
• sufficient: 'Sufficient' is an adjective and cannot correctly modify 'integrated' in this context, which requires an adverb.
• suffering: 'Suffering' refers to experiencing pain or distress, which is unrelated to the context of integration and does not fit grammatically.
