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_si0s):
Calculate ( 7 + -4 ).

Question 1 (Question id: q_fSJA6u5):
How many times does the letter "w" appear in the text: "True answered the"? 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.
For string answers, include 'first_char' with the answer’s initial letter.
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_si0s": {"answer": 3}, "q_fSJA6u5": {"answer": 1}}}
