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_qxDSi7):
Solve for r: 30 - 4*r = -10 Respond with an integer.

Question 1 (Question id: q_A32e):
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: "things"

Question 2 (Question id: q_jfExeDXS):
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: "day"

Question 3 (Question id: q_2CTKVPr):
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 3 insects, 3 praying mantiss, 2 sheeps, 2 scorpions, 1 human?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_2CTKVPr.

For every question id, supply an object whose 'answer' field stores the solution.
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:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.

{"ground_truth": {"q_A32e": {"answer": "s", "original_string": "things"}, "q_jfExeDXS": {"answer": "y", "original_string": "day"}, "q_qxDSi7": {"answer": 10, "half_answer": 5}, "global_metadata": {"num_questions_asked": 4}}}
