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_PyvbXgxo):
Calculate 3 / 3.

Question 1 (Question id: q_jM8LD):
Find the value of a in the equation: 20*a - 15 = 225 Respond with an integer.

Question 2 (Question id: q_IYQ4):
How many times does the letter "u" appear in the text: "industry Yes"? 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.
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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_PyvbXgxo": {"answer": 1, "answer_type": "integer"}, "q_jM8LD": {"answer": 12, "answer_type": "integer", "additional_answer_info": {"half_answer": 6, "double_answer": 24}}, "q_IYQ4": {"answer": 1, "answer_type": "integer"}}}
