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_vKQiB):
Find the value of w in the equation: 15*w + 14 = 209 Respond with an integer.

Question 1 (Question id: q_DdTbjNN):
How many times does the letter "o" appear in the text: "for a little"? Respond with an integer.

Question 2 (Question id: q_4uaaLXQt):
Solve for h: 18 - 5*h = -67 Respond with an integer.

Question 3 (Question id: q_y8Ux):
Find the value of a in the equation: 19*a - 20 = 170 Respond with an integer.

Question 4 (Question id: q_5qQWUE):
Calculate 2 + 2 + 4.



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'.
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).
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.
