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_gq1aklz):
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: "ideas"

Question 1 (Question id: q_cSfN3):
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: "explain"



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'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.

Now provide the result JSON using the described format.

{"ground_truth": {"q_gq1aklz": {"answer": "s", "answer_type": "string", "original_string": "ideas"}, "q_cSfN3": {"answer": "n", "answer_type": "string", "original_string": "explain"}, "global_metadata": {"num_questions_asked": 2}}}
