Question

what is hpv?
hpv is the most common sexually - transmitted infection (sti). hpv is a different virus than hiv and hsv (herpes). hpv is so common that nearly all sexually active men and women get it at some point in their lives. there are many different types of hpv. some types can cause health problems including genital warts and cancers. but there are vaccines that can stop those health problems from happening. how is hpv spread? you can get hpv by having oral, vaginal, or anal sex with someone who has the virus. it is most commonly spread during vaginal or anal sex. hpv can be passed even when an infected person has no signs or symptoms. anyone who is sexually active can get hpv, even if you have had sex with only one person. you also can develop symptoms years after you have sex with someone who is infected making it hard to know when you first became infected.
according to the passage, what evidence supports the argument that hpv is easily spread from person to person?
hpv can be spread even when a person with hpv has no symptoms.
a vaccine that prevents hpv infection is available.
a person confirms the presence of hpv when genital warts are found on the body.
limiting sexual behaviors to strictly vaginal sex reduces the transmission of hpv to others.

Explanation:

The passage states that HPV can be passed even when an infected person has no signs or symptoms. This means that a person may unknowingly spread the virus, making it easy for transmission as there is no visible indication to prevent contact. The other options do not directly support the ease of spread. The availability of a vaccine (option 2) is about prevention, not spread. Confirming HPV presence via genital warts (option 3) is a detection method, not evidence of easy spread. Limiting sexual behavior reducing transmission (option 4) is about prevention, not showing ease of spread.

Answer:

HPV can be spread even when a person with HPV has no symptoms.
