This is absolutely spot on! Well done!
Reduced communicable disease = fewer children missing school = great access to education
Here are some more examples
• Promote employment= stable income= afford healthcare and nutritious foods= prevent deficiency disease
• Improve literacy= make better life decisions and practice basic health practices (e.g. washing hands after using the toilet, safe sex to prevent HIV/AIDS) = reduce incidence of communicable diseases
• Educated girls= girls better able to take care of their children and when to access healthcare= reduce U5MR
• Economic growth allows governments to invest in universal healthcare such as providing vaccination programs for children which helps to reduce communicable diseases (eg: measles, tuberculosis) (SDG 3).
• Educated girls (SDG 4) marry later, are more likely to space births and less likely to experience sexual violence which reduces the chance of HIV/AIDS (SDG 3).
• Educated people gain literacy skills (SDG 4) and are likely to learn about health promotion messages (eg: the importance of hand-washing) which can reduce morbidity from communicable diseases (SDG 3)
When answering a SAC / Exam question it is good to put in brackets where you have included a feature of the respective SDGs it makes marking easier, and therefore you're more likely to be awarded full marks. Read the examiner report to get a better understanding of this
All the best
