For questions like the first question in exercise 2.1, adding "(Write in n1; n2; n3 format)" to the question and enforcing it can make it easy for us to check the answer precisely. however, kids may not understand the significance of writing in n1; n2; n3 format. so, they may still write either n1;n2;n3 or n1,n2,n3 or n1 n2 n3 or n1, n2 and n3 etc.

Given that there are many questions like this where the answers will need a lot more processing to determine correctness precisely, let us make the following changes:

(i) Always, show "Here's an answer: <Answer>" after user has provided the answer.[We will make this more intelligent later by checking if answer is expected to be unique or whether users can answer differently as in the above example.]
(ii) Whether the user's answer is correct or not, we should provide the option of detailedQNAs and detailedAnswer if they exist.
