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.
