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_ABhS5):
Calculate 1 + 5.

Question 1 (Question id: q_QRv9TGF):
Solve for d: 3*d - 11 = 31 Respond with an integer.

Question 2 (Question id: q_zOrZD):
Determine the value of y that satisfies: 90*y - 270 = 1530 Respond with an integer.

Question 3 (Question id: q_6Xi6EX):
How many times does the letter "n" appear in the text: "Jules Verne"? 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.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the response to a question is a string, add a 'first_char' field containing its first character.
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.
