OPINION
¶ 1 Kenneth Falcone seeks review of the trial court’s partial denial of post-conviction relief After a jury trial, Falcone was convicted of two counts of sexual conduct with a minor and one count each of attempted sexual conduct, public sexual indecency to a minor under fifteen, and luring a minor for sexual exploitation. The jury also found the state had proven its allegations that the attempted sexual conduct and luring a child were dangerous crimes against children. The court sentenced Falcone to consecutive, fifteen-year terms of imprisonment for attempted sexual conduct and luring a minor,
*169
to be served concurrently with lesser terms on his convictions for public sexual indecency and sexual conduct. We affirmed his convictions and sentences on appeal.
State v. Fal-cone,
No. 2 CA-CR 2007-0055, ¶ 18,
Background
¶ 2 We limit our recitation of the facts to those relevant to the issue on review. Fourteen-year-old E. and sixteen-year-old M. met Falcone at a YMCA, where Falcone touched M. on his “privates” while in the whirlpool bath. E. and M. then agreed to go home with Falcone, and, once they had arrived at his house, Falcone engaged in sexual contact with M., some of which E. witnessed. Although Falcone attempted to touch E. “under his pants,” E. resisted his overtures.
¶ 3 At the close of M.’s testimony, one of the jurors submitted the following question: “At any time did M[.] tell the man how old he was or how old E[.] was?” The state objected to the question, arguing, “[A]ge is an affirmative defense and no [related] questions have been asked of him, so I would [o]bjeet to that. It’s an affirmative defense. It hasn’t been raised. It hasn’t been disclosed.” Defense counsel did not oppose the state’s position on the issue, and the trial court did not allow the question. At the state’s request, the court added a sentence to its jury instruction defining the culpable mental state of “knowingly,” (Jury Instruction 26) and thus informed the jury, “ ‘Knowingly’ ... does not require any knowledge of the age of the alleged victim.” 1 Defense counsel did not object to the instruction.
¶4 In its closing argument, the state referred to this instruction as well as the juror’s question that had been submitted but precluded, telling the jury that proof of Fal-cone’s “knowledge of the victims’ age[s was] not required” for his conviction on the counts charged and was “a non issue, one that ought to be dismissed by you during this trial and during deliberations.”
¶ 5 In his petition for post-conviction relief, Falcone argued trial counsel had been ineffective in failing to object to Jury Instruction 26 and in failing to oppose the state’s objection to the juror’s question about his knowledge of the victims’ ages. He also claimed appellate counsel had been ineffective in failing to raise these issues on appeal. 2
¶ 6 In a ruling issued after an evidentiary hearing, the trial court found trial and appellate counsel both had been ineffective in failing to challenge Jury Instruction 26, but only as that instruction pertained to public sexual indecency,
3
count four of the indictment, and luring a minor,
4
count five, finding Jury Instruction 26 was “a clearly erroneous instruction of law” as to those counts. The court vacated Falcone’s convictions and sentences for counts four and five, concluding “the failure of either trial or appellate counsel to object or to appeal this issue is a departure from reasonable and acceptable norms of practice for this jurisdiction” and the resulting prejudice to Falcone was “clear and apparent.”

See Strickland v. Washington,
*170
¶ 7 In contrast, the trial court found Fal-cone had failed to demonstrate either a deficiency in counsel’s performance or prejudice with respect to his convictions for count one — his attempted sexual conduct with E.— and counts two and three — his sexual conduct offenses involving M. The court did not address Falcone’s argument that the definition of sexual conduct with a minor found in A.R.S. § 13-1405 requires the state to prove, as an element of that offense, that a defendant knew the age of his victim when he engaged in sexual conduct with him. Instead, the court found that, with respect to the sexual conduct charges, Falcone had not been prejudiced by either Jury Instruction 26 or the preclusion of evidence because he “did not advance or disclose a claimed defense pursuant to A.R.S. § 13-1407[ (B) ] ... [which] permits a defendant charged with Sexual Conduct to advance a claim of mistake of fact as to the ages of victims when they are alleged to be 15, 16 or 17.” The court reasoned such a defense would not have been available with respect to count one, because E. had been fourteen years of age, or on counts two and three, because Falcone had not advanced or disclosed an affirmative defense with respect to those counts.
¶ 8 In his petition for review, Falcone challenges the trial court’s denial of relief on counts one, two, and three. He maintains counsel’s failure to object to an erroneous jury instruction, which was found by the court to constitute ineffective assistance as to counts four and five, “also infected [his] convictions on the first three counts,” because, he contends, “knowledge of the [victim]’s age is an element” of § 13-1405, and “Jury Instruction # 26 misstated the law as it relates to all counts.”
Discussion
¶ 9 Generally, we review a trial court’s denial of post-conviction relief for an abuse of discretion.
State v. Bennett,
¶ 10 As he did below, Falcone relies on A.R.S. § 13-202(A) to argue that a defendant’s knowledge of a victim’s age is an element of the offense of sexual conduct with a minor that must be proven by the state. Section 13-202(A) provides:
If a statute defining an offense prescribes a culpable mental state that is sufficient for commission of the offense without distinguishing among the elements of such offense, the prescribed mental state shall apply to each such element unless a contrary legislative purpose plainly appears.
According to Falcone, § 13-1405’s definition of sexual conduct as “knowingly engaging in sexual intercourse ... with any person who is under eighteen years of age” requires the state to prove a defendant was aware of both his conduct and the victim’s age, because the definition does not distinguish between the “conduct” required for commission of the offense and the “circumstance” — the victim’s lack of majority — that renders the conduct criminal. 6 See § 13 — 105(10)(b) (“[knowingly,” with respect to “conduct” or “circumstance” in statute defining offense, means “person is aware or believes that the person’s *171 conduct is of that nature or that the circumstance exists”).
¶ 11 In other circumstances, we have applied § 13-202(A) to resolve an ambiguity created when a modifier precedes multiple terms or phrases in a statute, and we must determine, for example, “how far down the sentence the word ‘knowingly’ is intended to travel.”

§ 5.1(b) (4th ed. 2003);
State v. Rivera,
¶ 12 But in contrast to the legislature’s enactment of the statutes considered in those decisions, when it established the offense of sexual conduct with a minor in § 13-1405, it contemporaneously enacted § 13-1407, which establishes a defense to § 13-1405 when the victim was fifteen, sixteen, or seventeen years old and the defendant did not know, and could not reasonably have known, the victim was under eighteen years of age. 8 1977 Ariz. Sess. Laws, eh. 142, § 63. Thus, the legislature’s contemporaneous enactment of § 13-1407(B) may constitute its expression of “a contrary legislative purpose,” § 13-202(A), that forecloses the interpretation of § 13-1405 Falcone suggests.
¶ 13 In construing a statute, we must “determine and give effect to legislative intent.”
City of Phx. v. Phx. Emp’t Relations Bd.,
¶ 14 We agree with Division One of this court that §§ 13-1405 and 13-1407(B) must be read
in pari materia
and that requiring the state to establish a defendant’s knowledge of a victim’s age to convict him of sexual conduct with a minor would render § 13-1407 inoperable.
State v. Gamez,
¶ 15 In construing the predecessor to § 13-1405, former A.R.S. § 13-611, 1962 Ariz. Sess. Laws, ch. 52, § 1, our supreme court rejected an argument similar to the one Falcone makes here and reversed a trial court’s direction of acquittal that had been based on evidence of the defendant’s “good faith” — but mistaken — “belief that the prose-cutrix was over the age of eighteen years.”

State v. Superior Court,
The offense here is of that class which, by reason of an unbroken line of judicial holdings, it can be said that the statute denounces the mere doing of the act as criminal, regardless of whether the perpetrator had a bad mind, [requiring only] the generalized intent to engage in a course of criminal conduct.
State v. Superior Court,
¶ 16 When Arizona’s criminal code was revised in 1978, the legislature eliminated the constructs of specific and general intent that the court had applied in
State v. Superior Court
and, in their place, “adopted the use of the four culpable mental states of intention, knowledge, recklessness, and criminal negligence.”
State v. Bridgeforth,
¶ 17 In its commentary to chapter 14, the Commission described the state of the law before the 1978 code revisions, identifying former § 13-611(B) as the predecessor to § 13-1405. Report of Arizona Criminal Code Commission at xiii. Noting the supreme court’s holding in
State v. Superior Court
that, under former § 13-611(B), “[a] good faith belief that the prosecutrix was over the age of consent is no defense,” the Commission stated, “The code changes this law if the victim is 15, 16, or 17,” citing the defense provision enacted as § 13-1407(B). Report of Arizona Criminal Code Commission at 151,
citing State v. Superior Court,
¶ 18 Thus, we conclude the legislature intended these statutes, read together, to provide that, pursuant to § 13-1405, the state is required to prove a defendant had knowingly engaged in sexual conduct and had done so *173 with a person who was, in fact, under the age of eighteen. But, pursuant to § 13-1407(B), a defendant may present an affirmative defense, limited to cases in which the victim was fifteen or older, if he can show he “did not know and could not reasonably have known” the victim’s age. 10
¶ 19 Finally, we are not persuaded by Falcone’s suggestion that we should avoid reading these statutes
in pari materia
based on our supreme court’s decision in
State v. Getz,
¶ 20 We find no abuse of discretion in the trial court’s denial of post-conviction relief from Falcone’s convictions for sexual conduct with a minor and attempted sexual conduct with a minor. Accordingly, although we grant review, we deny relief.
Notes
. The full instruction given was:
"Knowingly” means, with respect to conduct or to a circumstance described by a statute defining an offense that a person is aware of or believes that his conduct is of that nature or that the circumstance exists. It does not require any knowledge of the unlawfulness of the act or omission. It does not require any knowledge of the age of the alleged victim.
With the exception of its last sentence, which Falcone has challenged in these post-conviction proceedings, this instruction essentially tracks the definition of “knowingly” found in A.R.S. § 13-105(10)(b).
. Although Falcone asserted additional claims of ineffective assistance of trial and appellate counsel, the trial court’s resolution of those claims is not an issue on review.
. Section 13-1403(B), A.R.S., provides: "A person commits public sexual indecency to a minor if the person intentionally or knowingly engages in any of the acts listed in subsection A of this section and such person is reckless about whether a minor who is under fifteen years of age is present.”
. Section 13-3554(A), A.R.S., provides: "A person commits luring a minor for sexual exploitation by offering or soliciting sexual conduct with another person knowing or having reason to know that the other person is a minor.”
. The state did not file a cross-petition for review. Accordingly, the trial court’s decision to vacate Falcone’s convictions for counts four and five is not before us.
. Section 13-1405 provides, in relevant part:
A. A person commits sexual conduct with a minor by intentionally or knowingly engaging in sexual intercourse or oral sexual contact with any person who is under eighteen years of age.
B. Sexual conduct with a minor who is under fifteen years of age is a class 2 felony and is punishable pursuant to [A.R.S.] § 13-705. Sexual conduct with a minor who is at least fifteen years of age is a class 6 felony.
. Although we agree with the result reached by Division One of this court in
State v. Gamez,
. Section 13-1407(B) now provides:
It is a defense to a prosecution pursuant to §§ 13-1404 and 13-1405 in which the victim’s lack of consent is based on incapacity to consent because the victim was fifteen, sixteen or seventeen years of age if at the time the defendant engaged in the conduct constituting the offense the defendant did not know and could not reasonably have known the age of the victim.
. Former § 13-611 had defined rape in the first degree as "an act of sexual intercourse accomplished with a female, not the wife of the perpetrator” under specified circumstances, including the use of force or threats of force to overcome the victim's resistance. 1962 Ariz. Sess. Laws, ch. 52, § 1. Rape in the second degree was defined as "an act of sexual intercourse with a female, not the wife of the perpetrator, under the age of eighteen years, under circumstances not amounting to rape in the first degree.” Id.
. Further support for our conclusion may be found in our longstanding interpretation of § 13-1405.
