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_ODue):
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: "humans"

Question 1 (Question id: q_Vbafj):
Determine the value of q that satisfies: 54*q + 20 = 1046 Respond with an integer.

Question 2 (Question id: q_zXS1Cuc):
How many times does the letter "a" appear in the text: "men at once"? Respond with an integer.

Question 3 (Question id: q_vyPkoe):
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: "to"

Question 4 (Question id: q_On0Ve):
How many times does the letter "s" appear in the text: "himself As for"? Respond with an integer.

Question 5 (Question id: q_wfTMP):
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 horse, 4 fireflys, 4 crabs?
 Respond with an integer.

Question 6 (Question id: q_5x08):
Calculate -3 * ( 9 * -5 ).



Produce a JSON object whose top-level keys are the question ids.

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 question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered: count of questions present in your JSON.
• 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.
