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_RfmgvOj):
Calculate 6 / 6.

Question 1 (Question id: q_bHYd):
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: "in"

Question 2 (Question id: q_MSAx17):
Solve for w: 162*w + 1134 = 2916 Respond with an integer.

Question 3 (Question id: q_Hw0P):
How many times does the letter "e" appear in the text: "s EIN or"? Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

Each key’s value must be an object holding an 'answer' field.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
