Model Answer

No, relying solely on oral contraceptive pills is not completely safe or sufficient.

What oral pills can do: They change the hormonal balance of the body so that eggs are not released, thus preventing fertilisation and pregnancy.

What oral pills cannot do: They do not provide any barrier protection. They cannot prevent sexually transmitted diseases (STDs) such as gonorrhoea, syphilis, warts, and HIV-AIDS. Only condoms help prevent transmission of such infections.

Additional concern: Oral pills can cause side-effects due to hormonal changes.

Therefore, the couple should also use condoms for protection against STDs.

Explanation

Examiners expect two distinct points here: (1) what pills can prevent (pregnancy, by stopping ovulation) and (2) what they cannot prevent (STDs — name at least two). The conclusion that pills alone are insufficient because they offer no protection against STDs is the key evaluative point earning the third mark. Always link back to condoms as the method that addresses STD transmission. Mentioning side-effects is a bonus but not the central focus.
