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_X7BbZnIu):
Solve for w: 8 - 18*w = -208 Respond with an integer.

Question 1 (Question id: q_txSY):
Solve for q: -6*q - 12 = -108 Respond with an integer.

Question 2 (Question id: q_bVQg):
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 cows, 1 starfish, 3 wasps?
 Respond with an integer.

Question 3 (Question id: q_ufTvQe):
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: "grow"



Return a JSON with each question id (except for q_X7BbZnIu) as a key.

Each key’s value must be an object holding an 'answer' field. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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.
Add 'num_questions_answered' showing how many questions you answered.

Now provide the result JSON using the described format.

{"ground_truth": {"q_ufTvQe": {"answer": "w", "original_string": "grow"}, "q_bVQg": {"answer": 39, "task_type": "leg_counting"}, "q_txSY": {"answer": 16, "half_answer": 8}, "global_metadata": {"num_questions_asked": 4, "num_questions_answered": 3}}}
