Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_pNEhGO):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 jellyfishs, 2 butterflys, 2 insects, 4 deers?
 Respond with an integer.

Question 1 (Question id: q_eNq3MTXP):
How many times does the letter "s" appear in the text: "he was"? Respond with an integer.

Question 2 (Question id: q_O8Nc):
How many times does the letter "o" appear in the text: "to connect"? Respond with an integer.

Question 3 (Question id: q_usC5):
Calculate 5 - -1 - 1.



Output JSON where all question ids are keys, omitting q_pNEhGO.

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_eNq3MTXP": {"answer": 1}, "q_usC5": {"answer": 5}, "q_O8Nc": {"answer": 2, "half_answer": 1}}}
