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_DVbj3e):
Calculate ( -1 - -7 ).

Question 1 (Question id: q_B3YpVXu):
How many times does the letter "r" appear in the text: "him from"? Respond with an integer.



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.
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_DVbj3e": {"answer": 6, "half_answer": 3}, "q_B3YpVXu": {"answer": 1}}}
