heterosexual behavior.

having sex with multiple partners.

Explanation:

Analyze the question stem

The question asks for "One of the best predictors of getting an STI is". An STI is a Sexually Transmitted Infection. We need to evaluate which of the given behavioral options is most strongly associated with an increased risk of contracting an STI.

Evaluate the options

• homosexual behavior: While certain sexual practices within any group can carry different levels of risk, sexual orientation itself is not a direct behavioral predictor of getting an STI; risk is determined by specific behaviors rather than orientation.
• asking a partner about his or her sexual behavior: This is a protective communication behavior that typically helps reduce the risk of contracting STIs rather than predicting an infection.
• heterosexual behavior: Similar to homosexual behavior, heterosexual behavior in itself is not a direct predictor of contracting an STI; risk depends on specific sexual practices and safety measures.
• having sex with multiple partners: Engaging in sexual activity with multiple partners significantly increases the statistical probability of exposure to STIs, making it one of the strongest behavioral predictors of contracting an infection.

Formulate the conclusion

Having multiple sexual partners increases the network of potential exposure, which directly correlates with a higher risk of STI transmission. Therefore, "having sex with multiple partners" is the best predictor among the choices.

Answer:

• homosexual behavior.
• asking a partner about his or her sexual behavior.
• heterosexual behavior.
• having sex with multiple partners. (Correct answer)
