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_zISYUIm):
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_vOPowG):
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"

Question 2 (Question id: q_4TZvOwoh):
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: "the"



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

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_4TZvOwoh": {"answer": "e", "first_char": "e"}, "q_vOPowG": {"answer": "d", "first_char": "d"}}}
