A.I. Explanation:

Correct answer: emerging

Explanation: The word 'emerging' fits grammatically as it describes threats that are currently developing or becoming more prominent, aligning with the context of digital safety. It indicates that these threats are not yet fully realized but are on the rise, which is relevant in discussions about online safety.

Meaning: 'Emerging' means coming into existence or becoming apparent, particularly in the context of new threats that individuals need to be aware of in the digital landscape.

Wrong options:

• negligible: 'Negligible' means insignificant or not worth considering, which contradicts the idea of threats that require attention.
• extraneous: 'Extraneous' refers to something irrelevant or unrelated, which does not apply to the context of threats to personal information.
• etiquette: 'Etiquette' pertains to accepted social behavior, which is unrelated to the concept of threats in the context of online safety.

Correct answer: unfounded

Explanation: The term 'unfounded' is appropriate as it describes sources that lack a basis in fact or evidence, contrasting with reliable sources. This fits the context of discerning credible information in an era of misinformation.

Meaning: 'Unfounded' means having no foundation in fact or truth, indicating that the sources are not credible or trustworthy.

Wrong options:

• authoritative: 'Authoritative' refers to sources that are recognized as reliable and credible, which is the opposite of what is being described here.
• endorsed: 'Endorsed' implies approval or support, suggesting that the sources are validated, which does not fit the context of unreliable information.
• peer-reviewed: 'Peer-reviewed' indicates that a source has been evaluated by experts, which again contradicts the idea of unreliable sources.

Correct answer: etiquette

Explanation: The word 'etiquette' is suitable as it refers to the accepted norms and behaviors in online interactions, which is essential for fostering respectful communication in digital communities.

Meaning: 'Etiquette' means the customary code of polite behavior in society or among members of a particular profession or group, particularly relevant in online settings.

Wrong options:

• protocol: 'Protocol' refers to a formal set of rules or procedures, which is less about social behavior and more about technical guidelines, making it less fitting here.
• procedure: 'Procedure' indicates a series of actions conducted in a certain order, which does not capture the social aspect of online interactions.
• guideline: 'Guideline' suggests a general rule or principle, which is broader and less specific than 'etiquette' in the context of social interactions.

Correct answer: active

Explanation: The term 'active' is appropriate as it describes participation that is engaged and involved, which aligns with the context of contributing to the digital economy and civic life.

Meaning: 'Active' means engaging or participating fully, indicating a proactive approach to involvement in various aspects of life.

Wrong options:

• passive: 'Passive' implies a lack of engagement or involvement, which contradicts the idea of meaningful participation.
• sporadic: 'Sporadic' suggests irregular or occasional participation, which does not align with the idea of consistent engagement in the digital economy.
• intermittent: 'Intermittent' means occurring at irregular intervals, which again does not convey the idea of continuous and active participation.
