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_C1gt3):
Find the value of k in the equation: k = 1 Respond with an integer.

Question 1 (Question id: q_7TjW):
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"



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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.
Add 'num_questions_answered' showing how many questions you answered.
• 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_C1gt3": {"answer": 1}, "q_7TjW": {"answer": "s"}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": ["q_C1gt3"]}}}
