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_oDo5):
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 2 lobsters, 3 crickets, 4 ducks, 4 dogs, 1 crab?
 Respond with an integer.

Question 1 (Question id: q_2agcvw):
How many times does the letter "m" appear in the text: "mirror of"? Respond with an integer.

Question 2 (Question id: q_0znS):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "this"

Question 3 (Question id: q_P1pA):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "evolution"



Produce a JSON object whose top-level keys are the question ids.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_oDo5": {"answer": 72, "answer_type": "integer", "half_answer": 36}, "q_2agcvw": {"answer": 1, "answer_type": "integer"}, "q_0znS": {"answer": "s", "answer_type": "string", "first_char": "s", "original_string": "this"}, "q_P1pA": {"answer": "n", "answer_type": "string", "first_char": "n", "original_string": "evolution"}}}
