What is the test of relevance, relevance and abuse of discretion in determining the admissibility of evidence at trial?

"Only relevant evidence is admissible [citations], and all relevant evidence is admissible unless excluded under the federal or state Constitutions or by statute. [Citations.] The test of relevance is whether the evidence 'tends "logically, naturally, and by reasonable inference" to establish material facts such as identity, intent, or motive.' [Citation.] The trial court has broad discretion in determining the relevance of evidence, but lacks discretion to admit irrelevant evidence. [Citation.] We review for abuse of discretion a trial court's rulings on the admissibility of evidence. [Citations.]" (People v. Benavides (2005) 35 Cal.4th 69, 90.)
