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_PXmxP8w):
Solve for t: 18*t + 28 = 226 Respond with an integer.

Question 1 (Question id: q_3wrwb):
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"



Output JSON where all question ids are keys, omitting q_3wrwb.

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.
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_PXmxP8w": {"answer": 11}}}
