I did not mention anything about feathers trapping air for the bird question

My answer was:
Colder.The feathers is a poor conductor of heat so the swan loses heat slower, keeping the bird warm.
How many marks can i get?

[ZhenghuaParent]

Can I ask a question? Will the Mean of Science and Chinese be lower this year ? Since they are harder than last year’s? So there will be people scoring either very low or very high???

[PSLEYEAR]
