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_RKcKIjd):
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: "waiting"

Question 1 (Question id: q_6Oz3G):
How many times does the letter "e" appear in the text: "And there"? Respond with an integer.

Question 2 (Question id: q_9rTbs7M):
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: "and"



Create a JSON object keyed by every question id except q_6Oz3G.

The value for each key should be an object that contains the answer in the field 'answer'.
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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_RKcKIjd": {"answer": "g", "answer_type": "string", "original_string": "waiting"}, "q_9rTbs7M": {"answer": "d", "answer_type": "string", "original_string": "and"}}}
