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_6RBSpU1):
Calculate -9 * -9.

Question 1 (Question id: q_7pWg):
How many times does the letter "r" appear in the text: "practical outcome"? Respond with an integer.

Question 2 (Question id: q_y27O):
How many times does the letter "e" appear in the text: "whether as heat"? Respond with an integer.

Question 3 (Question id: q_6vJ4yM):
How many times does the letter "l" appear in the text: "only three"? Respond with an integer.

Question 4 (Question id: q_yoZ6H):
Determine the value of c that satisfies: 12*c + 29 = 149 Respond with an integer.

Question 5 (Question id: q_OPNbQ):
Calculate 6 * 1 - 0.



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

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
Add 'num_questions_answered' showing how many questions you answered.

Now provide the result JSON using the described format.
