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_wtKf):
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: "is"

Question 1 (Question id: q_f5ITu):
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 human, 4 crickets, 4 horses?
 Respond with an integer.

Question 2 (Question id: q_yIBcNttT):
How many times does the letter "g" appear in the text: "registered trademark"? Respond with an integer.

Question 3 (Question id: q_afKzKPcD):
Calculate 1 * 8 - 2.

Question 4 (Question id: q_co4T):
Calculate 3 - -9.



Create a JSON object keyed by every question id except q_co4T.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_afKzKPcD": {"answer": 6, "answer_type": "integer", "half_answer": 3}, "q_wtKf": {"answer": "s", "answer_type": "string", "first_char": "s"}, "q_f5ITu": {"answer": 42, "answer_type": "integer", "half_answer": 21}, "q_yIBcNttT": {"answer": 1, "answer_type": "integer"}}}
