Explanation:

Question 5

Step1: Assume graph shows chlamydia rate for girls 15 - 19 is 2626 per 100,000.

Step2: Calculate cases in 1.5 million: $\frac{2626}{100000}×1500000 = 2626×15 = 39390$.

Question 6

Untreated STDs (like chlamydia/gonorrhea) can lead to pelvic inflammatory disease (PID) in females. Endometriosis is not STD - related, yeast infection/vaginitis have other causes.

Question 7

Untreated STDs (e.g., chlamydia) can damage reproductive organs, leading to infertility. Toxic shock is from tampons, premenstrual syndrome is hormonal, STDs don't cause pregnancy (they may complicate it but not cause it).

Question 8

Answer:

C. 39,390
