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_fyE92y):
How many times does the letter "u" appear in the text: "you do"? Respond with an integer.

Question 1 (Question id: q_lCgs7B):
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: "the"

Question 2 (Question id: q_VNEVeml):
Calculate ( ( ( -4 + 8 ) ) ).



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
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_fyE92y": {"answer": 1, "answer_type": "integer"}, "q_lCgs7B": {"answer": "e", "answer_type": "string", "first_char": "e"}, "q_VNEVeml": {"answer": 4, "answer_type": "integer", "half_answer": 2}}}
