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_E5KRf6mB):
How many times does the letter "a" appear in the text: "but can"? Respond with an integer.

Question 1 (Question id: q_arydPsb):
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: "subject"

Question 2 (Question id: q_8CI8Ha):
Calculate ( 3 - 3 ).

Question 3 (Question id: q_ApbCqgz):
Find the value of m in the equation: 240*m - 333 = 387 Respond with an integer.

Question 4 (Question id: q_800CrFsy):
How many times does the letter "b" appear in the text: "works by"? Respond with an integer.



Create a JSON object keyed by every question id except q_800CrFsy.

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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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_arydPsb": {"answer": "t", "original_string": "subject"}, "q_8CI8Ha": {"answer": 0, "half_answer": 0}, "q_ApbCqgz": {"answer": 3}, "q_E5KRf6mB": {"answer": 1}}}
