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_lCzKp):
How many times does the letter "n" appear in the text: "Do not"? Respond with an integer.

Question 1 (Question id: q_ZL0AlZ):
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: "compete"

Question 2 (Question id: q_KHUJm25):
How many times does the letter "n" appear in the text: "department and tell"? Respond with an integer.

Question 3 (Question id: q_1oAaFmt):
Calculate ( ( -5 + 0 ) * -2 ).

Question 4 (Question id: q_QfQW6):
Solve for d: 20 - 15*d = -160 Respond with an integer.



Output JSON where all question ids are keys, omitting q_QfQW6, q_1oAaFmt.

For every question id, supply an object whose 'answer' field stores the solution.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_lCzKp": {"answer": 1}, "q_ZL0AlZ": {"answer": "e", "first_char": "e"}, "q_KHUJm25": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}}}
