Model Answer
(i) Two non-surgical contraceptive methods Radha can use:
- Mechanical barrier method – Use of condom (on penis) or similar covering worn in the vagina, which prevents sperm from reaching the egg.
- Hormonal pills (oral pills) – These change the hormonal balance of the body so that eggs are not released and fertilisation cannot occur.
(She could also use copper-T / loop placed in the uterus to prevent pregnancy.)
(ii) Surgical methods to prevent pregnancy:
- Vasectomy – The vas deferens in the male is blocked, preventing sperm transfer.
- Tubectomy – The fallopian tube in the female is blocked, preventing the egg from reaching the uterus.
In both cases, fertilisation does not take place.
(iii) Examples of sexually transmitted diseases (STDs):
- Caused by bacteria: Gonorrhoea / Syphilis
- Caused by virus: HIV-AIDS / Warts

Explanation
- For part (i), name two methods clearly — barrier (condom/vaginal covering), hormonal pills, or copper-T/loop are all valid; pick any two.
- For part (ii), examiners expect the specific names vasectomy and tubectomy along with a one-line explanation of each.
- For part (iii), the passage directly names gonorrhoea and syphilis (bacterial) and warts and HIV-AIDS (viral) — use these exact examples for full marks.
- Avoid writing more than needed; crisp, labelled points score well in 5-mark questions.
