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_aDF6jo):
Determine the value of q that satisfies: 171*q = 2394 Respond with an integer.

Question 1 (Question id: q_7S8m3):
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: "why"



Output JSON where all question ids are keys, omitting q_aDF6jo.

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_7S8m3": {"answer": "y", "original_string": "why"}}}
