In some cultures, the use of _____ is considered appropriate in written discourse.

The use of passive voice in written discourse is often considered appropriate in certain cultures for a variety of reasons linked to formality and objectivity. In many academic and professional contexts, employing passive voice allows the writer to emphasize the action or outcome rather than the individual performing the action. This can create a sense of neutrality, which is especially valued in formal writing where the focus is intended to be on the research or findings rather than the researcher or author's opinions.

In cultures that emphasize collectivism or formality, this style aligns with social norms that prioritize the group or institutional knowledge over personal expression. Additionally, using passive voice can serve to soften assertive statements, making the writing less confrontational and more respectful, which is valued in communication practices within these cultures.

The other options, such as active voice, direct speech, and colloquialism, may be more characteristic of cultures that favor personal expression, clarity, and informality, which may not align with the same conventions of formality or objectivity that are appreciated in contexts where passive construction is preferred.
