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_hFd4ZSHp):
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: "values"

Question 1 (Question id: q_nDqWE):
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: "those"

Question 2 (Question id: q_3zfeW5R):
Solve for n: 35 - 18*n = 17 Respond with an integer.

Question 3 (Question id: q_5O9hvon):
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 4 sheeps, 4 wasps, 4 tigers, 2 cockroachs?
 Respond with an integer.



Return a JSON with each question id (except for q_hFd4ZSHp) as a key.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.
When counting animal legs, include an 'animal_types' list of the distinct animal names (singular, sorted).

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
• num_questions_answered: count of questions present in your JSON.

Now provide the result JSON using the described format.
