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_PEWz1):
How many times does the letter "o" appear in the text: "Faithburn The doctor"? Respond with an integer.

Question 1 (Question id: q_vNhdz):
Solve for q: 260*q - 480 = 560 Respond with an integer.

Question 2 (Question id: q_marmwOuo):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 butterflys, 2 beetles, 3 deers?
 Respond with an integer.



Return a JSON with each question id as a key.

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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
