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_jZzVuJrS):
Solve for f: 19*f - 10 = 161 Respond with an integer.

Question 1 (Question id: q_qam7GCc):
Calculate 5 + 1 * 7.

Question 2 (Question id: q_vQ8Io9):
Calculate 0 * -9 * 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'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.
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 – total number of questions originally shown.
'num_questions_answered' must hold the number of answered questions.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.
