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_X2RtDt0P):
How many times does the letter "e" appear in the text: "by horses were"? Respond with an integer.

Question 1 (Question id: q_cdCx):
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 cockroachs, 1 crab, 4 praying mantiss, 4 cats?
 Respond with an integer.

Question 2 (Question id: q_EpHpBP):
Calculate ( -5 * -3 ).



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'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_X2RtDt0P": {"answer": 3, "answer_type": "integer"}, "q_cdCx": {"answer": 62, "answer_type": "integer", "additional_answer_info": {"half_answer": 31, "double_answer": 124}}, "q_EpHpBP": {"answer": 15, "answer_type": "integer"}}}
