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_E3VJ4E):
Find the value of x in the equation: 21 - 17*x = -149 Respond with an integer.

Question 1 (Question id: q_92om0d):
Calculate ( 3 * 9 ).

Question 2 (Question id: q_hHa7r):
How many times does the letter "h" appear in the text: "of each new"? Respond with an integer.

Question 3 (Question id: q_xqw472nE):
How many times does the letter "o" appear in the text: "E 7 Do"? Respond with an integer.

Question 4 (Question id: q_A4CSVtT):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 bird, 1 cricket, 4 sea slugs?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_E3VJ4E.

Each key’s value must be an object holding an 'answer' field.
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.
For string answers, include 'first_char' with the answer’s initial letter.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.
