In academic or formal writing, the choice between coordination (parataxis) and subordination (hypotaxis) significantly affects textual density and information hierarchy. Analyze the statements regarding these mechanisms:
I.Subordination creates a hierarchy of information, allowing the writer to background less important information (in the dependent clause) and foreground the main point (in the independent clause).
II.Heavy nominalization, often associated with subordination, tends to decrease lexical density, making the text resemble spoken language more closely.
III.Coordination links clauses of equal grammatical status, which can sometimes lead to ambiguity regarding the logical relationship between ideas if explicit connectors are not used.

Choose the alternative that indicates the correct statement(s).
