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_nyNLo9):
How many times does the letter "l" appear in the text: "faint rumbling was"? Respond with an integer.

Question 1 (Question id: q_HZmwmIH):
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: "important"

Question 2 (Question id: q_AAWtU2):
Solve for a: 155 - 8*a = 131 Respond with an integer.

Question 3 (Question id: q_IVsM):
How many times does the letter "h" appear in the text: "any of the"? Respond with an integer.

Question 4 (Question id: q_X96Mvf6):
How many times does the letter "o" appear in the text: "have answered Cooley"? Respond with an integer.

Question 5 (Question id: q_13hQr):
Calculate 5 + 1 * 7.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_nyNLo9": {"answer": 1}, "q_HZmwmIH": {"answer": "t", "original_string": "important"}, "q_AAWtU2": {"answer": 3}, "q_IVsM": {"answer": 1}, "q_X96Mvf6": {"answer": 2, "half_answer": 1}, "q_13hQr": {"answer": 12, "half_answer": 6}}}
