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_4Dxc):
Calculate -7 - 4 * -7.

Question 1 (Question id: q_dGOndL):
Solve for d: 8*d - 12 = 92 Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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.
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_4Dxc": {"answer": 21, "answer_type": "integer"}, "q_dGOndL": {"answer": 13, "answer_type": "integer"}}}
