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_Tw8Tm):
Find the value of v in the equation: 8 - 9*v = -10 Respond with an integer.

Question 1 (Question id: q_W1ZEf):
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: "economy"

Question 2 (Question id: q_lx3LjbVk):
Solve for w: 162*w + 1134 = 2916 Respond with an integer.

Question 3 (Question id: q_sebTQE6b):
Calculate ( -9 * -2 + -4 ).

Question 4 (Question id: q_lxFoG):
How many times does the letter "o" appear in the text: "days of"? Respond with an integer.



Create a JSON object keyed by every question id except q_W1ZEf, q_sebTQE6b.

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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_lx3LjbVk": {"answer": 11, "answer_type": "integer"}, "q_Tw8Tm": {"answer": 2, "answer_type": "integer", "half_answer": 1}, "q_lxFoG": {"answer": 1, "answer_type": "integer"}}}
