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_jc6n):
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: "also"

Question 1 (Question id: q_qhTW0vo):
Calculate -4 + 6.

Question 2 (Question id: q_gTQLX0ky):
How many times does the letter "a" appear in the text: "a veritable"? Respond with an integer.

Question 3 (Question id: q_kKLhnHMK):
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: "challenging"

Question 4 (Question id: q_fAQpr92):
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 cricket, 1 wasp, 4 leechs, 3 lobsters?
 Respond with an integer.

Question 5 (Question id: q_UfUgaz):
Calculate ( -8 * -9 ).

Question 6 (Question id: q_NJmyb2):
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 giraffes, 4 woodlouses, 4 ducks, 4 snakes?
 Respond with an integer.

Question 7 (Question id: q_DC1WgPd):
Calculate ( ( 7 * 9 ) ).



Create a JSON object keyed by every question id except q_gTQLX0ky, q_fAQpr92.

For every question id, supply an object whose 'answer' field stores the solution.
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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.
For animal-leg questions, add 'animal_types': an alphabetically-sorted list of unique animal names in singular form.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.
