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_7vKp5Lt):
Calculate 4 + 0 - -8.

Question 1 (Question id: q_CbjYdU7):
How many times does the letter "6" appear in the text: "64 6221541"? Respond with an integer.

Question 2 (Question id: q_C4Cqi9g):
Find the value of w in the equation: 16*w - 15 = 81 Respond with an integer.



Output JSON where all question ids are keys, omitting q_C4Cqi9g.

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.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Also include 'combined_results' consisting of:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
