Hi all,
Pls help me with this qns... Thks thks!
How should food be stored so that mould cannot grow on it too quickly and cause it to spoil?
A. Food should be kept in a fridge
B. Food should be kept in a well-ventilated cupboard
C. Food should be kept in an airtight container .
D. Food should be kept in under a netted food cover
E. Natural preservative such as vinegar should be added to the food.
(1) A and C
(2) B and D
(3) A, C and E
(4) B, D and E
- air ( kept in air-tight container)
- moisture
- warmth (food to be kept in fridge)
Not all things you want to add vinegar as a preservative right!
Please do share with us the answer when you have them. -
I think it 3 as just like you have said, not all but it is asking how and how got a lot of ways not only because not all do.

Concept Tested here: Mould needs air, warmth and water to grow.
Clearly, Option A: Food in refrigerator has no warmth.
Option
Food in air-tight container has no air.
Option E: Although this is not what the pupils have learnt about the conditions of growth for mould, but this is a common-sense solution to prevent mould from growing.
Answer for this question: Option 3 (A, C and E)
Increasingly, PSLE has shifted to test on common-sense questions rather than strictly text-book based syllabus. We have to adapt.
