Sam and his friends, Tom and Vanessa, wanted to find out the conditions needed for mould to grow. They prepared the set-ups as shown in the diagram below.
The set-ups were kept at the locations and conditions as shown in the table below.
| Set-up A | Set-up B | Set-up C | |
| Location | kitchen | freezer | kitchen |
| Temperature of location | 30ºC | 0ºC | 30ºC |
Three days later, they found mould growing on the rice in Set-up C but not in Set-ups A and B.
Based on their observation, Sam and his friends suggested why mould did not grow in Set-ups A and B.
Sam: “There was a lack of moisture in Set-up A.”
Tom: “There was not enough warmth in Set-up B.”
Vanessa: “There was not enough air in Set-up B.”
