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_lfnb):
How many times does the letter "i" appear in the text: "table furnished forth"? Respond with an integer.

Question 1 (Question id: q_TtEL):
Solve for f: 31 - 9*f = -104 Respond with an integer.

Question 2 (Question id: q_bYotK):
How many times does the letter "e" appear in the text: "access to"? Respond with an integer.

Question 3 (Question id: q_tod6):
How many times does the letter "s" appear in the text: "Here is a"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.
'num_questions_answered' must hold the number of answered questions.

Now provide the result JSON using the described format.
