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_gdI0):
Calculate 5 / 1.

Question 1 (Question id: q_ugC23ACE):
Find the value of b in the equation: 6 - 2*b = -30 Respond with an integer.

Question 2 (Question id: q_xatK):
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: "and"

Question 3 (Question id: q_geKpwof):
How many times does the letter "t" appear in the text: "at the call"? Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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_gdI0": {"answer": 5}, "q_ugC23ACE": {"answer": 18, "half_answer": 9}, "q_xatK": {"answer": "d", "original_string": "and"}, "q_geKpwof": {"answer": 2, "half_answer": 1}}}
