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_aRIQipQ):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "how"

Question 1 (Question id: q_QSQv):
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 2 cockroachs, 4 grasshoppers, 2 ants?
 Respond with an integer.

Question 2 (Question id: q_rOx6UhcE):
How many times does the letter "e" appear in the text: "domestic kitchen and"? Respond with an integer.

Question 3 (Question id: q_jyNgf1):
Calculate ( ( 0 + 5 ) ).



Output JSON where all question ids are keys, omitting q_rOx6UhcE.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

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 – number you actually answered.

Now provide the result JSON using the described format.
