What does the author's supposition about American critics imply regarding their influence on artists?

The author’s supposition about American critics suggests that critics possess a significant influence over how artists perceive and navigate the value of their work. This idea indicates that critics play a crucial role in shaping the beliefs and standards surrounding art, impacting artists' evaluations of what constitutes "good" or "bad" art.

The reasoning behind selecting this option is rooted in the understanding that critics often help define artistic trends and standards, which artists may either internalize or respond to. By offering assessments and insights, critics can guide artists in how they approach their craft, ultimately affecting their creative output.

The other options do not align with this perspective, as they either downplay the critics' role or suggest a simplistic relationship between critics and artists that overlooks the nuances of influence in the artistic community.
