Question

which characteristics should be avoided in formal writing?
○ scholarly language
○ complex sentences
○ opinion statements
○ lengthy descriptions

Explanation:

In formal writing, the goal is to present objective information, arguments, or analysis. Scholarly language is appropriate, complex sentences can be used for precision, and lengthy descriptions might be necessary in some cases (e.g., detailed explanations in research). However, opinion statements (which reflect personal views without supporting evidence or in an unsubstantiated way) are generally avoided as formal writing emphasizes objectivity and evidence - based content.

Answer:

C. opinion statements
