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_pzjMZ):
How many times does the letter "d" appear in the text: "editor and"? Respond with an integer.

Question 1 (Question id: q_aLkvJD):
Find the value of l in the equation: 168*l - 14 = 1498 Respond with an integer.

Question 2 (Question id: q_Ep0gC):
Determine the value of v that satisfies: 28*v = 420 Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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_pzjMZ": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_Ep0gC": {"answer": 15}}}
