The overall number of cases of STIs is:

Choice A reason: The HPV vaccine can help prevent cervical cancer, as it protects against the most common types of HPV that cause cervical cancer. HPV is a sexually transmitted infection that can infect the cervix and cause abnormal cell changes that may lead to cancer. The HPV vaccine is recommended for both males and females between the ages of 9 and 26.

Choice B reason: The HPV vaccine will not protect you from all types of the virus, as there are more than 100 types of HPV, and the vaccine only covers 9 of them. However, these 9 types are responsible for about 90% of cervical cancers and 80% of anal cancers. The vaccine also does not protect against other sexually transmitted infections, such as chlamydia, gonorrhea, or HIV.

Choice C reason: You will not need to have a booster vaccination each year, as the HPV vaccine is given in a series of 2 or 3 doses, depending on the age of the person. The vaccine provides long-lasting protection, and no additional doses are needed after completing the series.

Choice D reason: You will still need to get a routine cervical exam, as the HPV vaccine does not eliminate the risk of cervical cancer completely. The vaccine does not protect against all types of HPV, and some people may already be infected with HPV before getting the vaccine. Therefore, regular screening with a Pap test and/or an HPV test is still recommended for women aged 21 to 65 to detect any abnormal cells or HPV infection in the cervix.

Choice A reason: Fresh fruits are incorrect because they are not rich sources of iron. They are good sources of vitamin C, which can enhance iron absorption, but they do not provide enough iron by themselves.

Choice B reason: Milk and cheese are incorrect because they are not rich sources of iron. They are good sources of calcium, which is important for bone health, but they can interfere with iron absorption if consumed in excess.

Choice C reason: Whole grain breads are incorrect because they are not rich sources of iron. They are good sources of complex carbohydrates, which provide energy and fiber, but they contain phytates, which can inhibit iron absorption.

Choice D reason: Red meat and organ meats are correct because they are rich sources of iron. They contain heme iron, which is more easily absorbed by the body than non-heme iron from plant sources. They also provide protein, which is essential for tissue growth and repair.
