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_dnGL):
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_awu95N):
How many times does the letter "r" appear in the text: "well know everything"? Respond with an integer.

Question 2 (Question id: q_UBnw):
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"



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.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_dnGL": {"answer": "o", "answer_type": "string", "original_string": "to"}, "q_awu95N": {"answer": 1, "answer_type": "integer"}, "q_UBnw": {"answer": "d", "answer_type": "string", "original_string": "and"}}}
