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_sk9Lku3):
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: "country"

Question 1 (Question id: q_XuPhly1k):
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 sea slug, 2 cows, 2 giraffes, 4 lobsters?
 Respond with an integer.

Question 2 (Question id: q_6C7L):
Calculate 8 + -1.

Question 3 (Question id: q_CH4MVS):
How many times does the letter "u" appear in the text: "Furthermore each"? Respond with an integer.

Question 4 (Question id: q_2RD6O):
Calculate 7 - -5 + 7.



Output JSON where all question ids are keys, omitting q_6C7L.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
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: how many questions were asked in total.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.
