Kinda pissed i got a couple of questions wrong from 2009 VCAA exam... help me out please

Question 17
In terms of participant selection, should these results be generalised?
Explain your answer.

Actual answer : No, these results should not be generalised.
Any of:
• participants were selected according to who volunteered in the first 100
• participants were not randomly selected
• not every Grade 4 child had an equal chance of being selected.


My Answer: No, the results are firstly not statistically significant. The sample size is also too small(100 participants) and may not be representative of the population to be generalized.

So why is my answer wrong?? T.T
My teacher told me if it's generalisation, you have to comment on how the participants were selected and the allocation. If participant's were not randomly selected/allocated, results cannot be generalised because it's not representative of the polulation. If it ask's for the conclusion, then you need to comment on the inferential statistics (statistically significant or not), if p-value is less than 0.05, than there is no conclusions.
