A.I. Explanation:

Correct answer: very

Explanation: The word 'very' serves as an intensifier, emphasizing the extent to which digital media has reshaped the fabric of social interaction and cultural expression. It fits grammatically as it modifies the noun 'fabric' and aligns contextually with the sentence's assertion about the significant impact of digital media.

Meaning: 'Very' means to a high degree or extremely, indicating that the reshaping of social interaction and cultural expression is substantial.

Wrong options:

• somehow: 'Somehow' suggests an unspecified manner, which does not convey the intensity needed in this context.
• somewhat: 'Somewhat' implies a lesser degree of impact, which contradicts the strong assertion made in the sentence.
• both: 'Both' indicates two items or aspects, which does not apply here as the sentence discusses a singular impact.

Correct answer: birth

Explanation: The word 'birth' indicates the emergence or creation of new cultural phenomena, fitting grammatically as a noun that serves as the subject of the clause. Contextually, it aligns with the idea of digital media giving rise to new developments.

Meaning: 'Birth' refers to the beginning or emergence of something, in this case, novel cultural phenomena resulting from digital media.

Wrong options:

• movement: 'Movement' refers to a change or development, but does not convey the idea of creation or emergence as effectively as 'birth.'
• sight: 'Sight' pertains to vision or perception, which is irrelevant in this context of cultural phenomena.
• development: 'Development' implies a process of growth or evolution, but lacks the connotation of a definitive beginning that 'birth' provides.

Correct answer: examines

Explanation: The word 'examines' is a verb that indicates a detailed investigation or analysis, fitting grammatically as it describes the action performed by researchers. Contextually, it aligns with the focus of digital anthropologists and sociologists on understanding the impact of digital media.

Meaning: 'Examines' means to inspect or analyze something carefully, in this case, the influence of digital media on societal dynamics.

Wrong options:

• installs: 'Installs' refers to setting up or establishing something, which does not fit the context of research and analysis.
• claims: 'Claims' suggests making a statement or assertion, which lacks the analytical nuance required in this context.
• admits: 'Admits' implies acknowledging something, which does not convey the active investigation that 'examines' does.

Correct answer: practices

Explanation: The word 'practices' refers to established methods or customs, fitting grammatically as a plural noun that complements the context of cultural activities. It aligns with the sentence's discussion of how digital media transforms traditional cultural norms.

Meaning: 'Practices' means the habitual actions or customs of a group, indicating the traditional ways that are being transformed by digital media.

Wrong options:

• manuals: 'Manuals' refers to instructional books or guides, which does not relate to cultural activities or customs.
• cores: 'Cores' suggests central parts or essential elements, which is not relevant in the context of cultural practices.
• comments: 'Comments' refers to remarks or observations, which does not fit the context of established cultural methods.
