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_EADS2r4h):
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: "endangered"

Question 1 (Question id: q_lIxkW5):
Calculate -4 * -4.



Your output must be a JSON mapping every question id to its answer info.

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.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_EADS2r4h": {"answer": "d", "answer_type": "string"}, "q_lIxkW5": {"answer": 16, "answer_type": "integer", "additional_answer_info": {"half_answer": 8, "double_answer": 32}}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_lIxkW5"]}}}
