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_PHkjPW):
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"

Question 1 (Question id: q_SpvCYw):
Solve for z: 19 - 6*z = 7 Respond with an integer.

Question 2 (Question id: q_qG5Wr):
How many times does the letter "v" appear in the text: "every day"? Respond with an integer.



Return a JSON with each question id as a key.

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.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_PHkjPW": {"answer": "e", "answer_type": "string", "first_char": "e"}, "q_SpvCYw": {"answer": 2, "answer_type": "integer", "half_answer": 1}, "q_qG5Wr": {"answer": 1, "answer_type": "integer"}}}
