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_dx9GXNB):
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: "to"

Question 1 (Question id: q_GXij53G):
How many times does the letter "m" appear in the text: "our modern towns"? Respond with an integer.



Create a JSON object keyed by every question id except q_dx9GXNB.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the response to a question is a string, add a 'first_char' field containing its first character.
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:
Include 'num_questions_asked' to record the total number of questions presented.
'num_questions_answered' must hold the number of answered questions.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.

{"ground_truth": {"q_GXij53G": {"answer": 1}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 1, "questions_with_integer_answers": ["q_GXij53G"]}}}
