Answer the following question given this paragraph: The prevalence of cervical cancer in the United States is very low because of regular screening exams called pap smears. Pap smears sample cells of the cervix, allowing the detection of abnormal cells. If pre-cancerous cells are detected, there are several highly effective techniques that are currently in use to remove them before they pose a danger. However, women in developing countries often do not have access to regular pap smears. As a result, these women account for as many as 80 percent of the cases of cervical cancer worldwide. In 2006, the first vaccine against the high-risk types of HPV was approved. There are now two HPV vaccines available: Gardasil®️ and Cervarix®️. Whereas these vaccines were initially only targeted for women, because HPV is sexually transmitted, both men and women require vaccination for this approach to achieve its maximum efficacy. A recent study suggests that the HPV vaccine has cut the rates of HPV infection by the four targeted strains at least in half. Unfortunately, the high cost of manufacturing the vaccine is currently limiting access to many women worldwide. Q: The prevalence of cervical cancer in the united states is very low because of regular screening exams called what? Choices: - prostates exams - mammograms - Stavros smears - pap smears A:
**Answer**
pap smears

Lead sulfates and carbonates are very insoluble, so will precipitate out of solution very easily. Q: Is purifying water a simple or complicated process? Choices: - expensive - impossible - simple - complicated A:
**Answer**
complicated
