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_POJW):
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 woodlouses, 2 fireflys, 4 butterflys, 3 ducks?
 Respond with an integer.

Question 1 (Question id: q_Dnv29):
Find the value of m in the equation: 8*m + 13 = 53 Respond with an integer.

Question 2 (Question id: q_TVgLM2F):
Find the value of x in the equation: 60*x - 220 = 860 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_POJW": {"answer": 98, "half_answer": 49}, "q_Dnv29": {"answer": 5}, "q_TVgLM2F": {"answer": 18, "half_answer": 9}}}
