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_rZRjguKH):
How many times does the letter "u" appear in the text: "in our day"? Respond with an integer.

Question 1 (Question id: q_ubHN4NHv):
Determine the value of i that satisfies: 4*i - 1 = 47 Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_rZRjguKH": {"answer": 1, "answer_type": "integer"}, "q_ubHN4NHv": {"answer": 12, "answer_type": "integer", "half_answer": 6}}}
