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

Question 1 (Question id: q_U00Z):
Calculate 9 / 3.

Question 2 (Question id: q_fpK9p8cK):
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: "competition"

Question 3 (Question id: q_KKZKyd):
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: "money"



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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_mZDnFniB": {"answer": 11}, "q_U00Z": {"answer": 3}, "q_fpK9p8cK": {"answer": "n", "first_char": "n", "original_string": "competition"}, "q_KKZKyd": {"answer": "y", "first_char": "y", "original_string": "money"}}}
