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_dAriNC):
Solve for p: 12*p + 15 = 51 Respond with an integer.

Question 1 (Question id: q_yZTdw):
Calculate -7 - -8.

Question 2 (Question id: q_lI8v):
Solve for r: 6 - 4*r = -74 Respond with an integer.

Question 3 (Question id: q_WjK1JB3):
Calculate -6 - -3 * 9.

Question 4 (Question id: q_TllsMmZa):
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: "made"

Question 5 (Question id: q_8vEeZL):
Calculate 2 - -7.



Create a JSON object keyed by every question id except q_dAriNC, q_8vEeZL.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_TllsMmZa": {"answer": "e", "answer_type": "string", "first_char": "e"}, "q_WjK1JB3": {"answer": 21, "answer_type": "integer"}, "q_yZTdw": {"answer": 1, "answer_type": "integer"}, "q_lI8v": {"answer": 20, "answer_type": "integer", "half_answer": 10}}}
