Select the two answer choices that complete the sentence: The storylines of silent dramas may often have been _____, yet within those basic narrative outlines the true artists among silent-film actors could express emotional subtleties that have no analogue in spoken language.

This choice suggests that the storylines lack believability, which does not align with the intent of the sentence. Silent dramas often utilized straightforward plots that, while simple, were not inherently implausible; rather, they relied on emotional expression to convey depth.

While "incredible" could suggest that the storylines are remarkable, it does not capture the essence of the basic narrative structures typical of silent dramas. The term does not fit the context of the sentence, which emphasizes foundational storytelling rather than extraordinary plots.

The term "conventional" implies adherence to traditional storytelling methods, which may not fully encompass the simplicity of silent film narratives. While some plots may have been conventional, the focus here is on the elemental nature of the stories rather than their conformity to established norms.

While this choice indicates simplicity, it leans towards a negative connotation of being overly simplistic or lacking sophistication. The sentence highlights that these basic narratives still allow for emotional depth, making "elemental" a more appropriate choice.

This option suggests that the storylines are difficult to follow, which contradicts the notion of basic narrative outlines. Silent dramas typically presented clear, straightforward plots to facilitate emotional expression, making "confusing" unsuitable in this context.
