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_qsVhf):
Calculate 8 / 2.

Question 1 (Question id: q_GOvRa9):
Solve for r: 6 - 4*r = -74 Respond with an integer.

Question 2 (Question id: q_nNGTJ8k):
How many times does the letter "a" appear in the text: "any of"? Respond with an integer.

Question 3 (Question id: q_bUNeXz):
Calculate 8 / 4.

Question 4 (Question id: q_dCPi7):
How many times does the letter "w" appear in the text: "height with"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
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 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.
