What is the test for a jury to convict a defendant of a violation of a criminal statute?

"As a general rule, when violation of a criminal statute is charged and the evidence establishes several acts, any one of which could constitute the crime charged, either the state must select the particular act upon which it relied for the allegation of the information, or the jury must be instructed that it must agree unanimously upon which act to base a verdict of guilty." (People v. Jennings (2010) 50 Cal.4th 616, 679.) Unanimity is not necessary if both acts are part of a single course of conduct, or if the defendant offers the same defense or defenses to the various acts constituting the charged crime. (Ibid.)
