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_6ibmR0):
How many times does the letter "a" appear in the text: "on rails"? Respond with an integer.

Question 1 (Question id: q_ZMuM4h):
Calculate -8 * -7 + 2.

Question 2 (Question id: q_OWVmbD):
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 3 sheeps, 2 spiders, 1 elephant, 2 fireflys, 3 sea slugs?
 Respond with an integer.

Question 3 (Question id: q_pCAZ):
Calculate 7 + -8 / 2.

Question 4 (Question id: q_Z7sBmYo):
How many times does the letter "h" appear in the text: "in length"? Respond with an integer.

Question 5 (Question id: q_6KMJN0c):
Calculate -2 / 2 + 5.



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'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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.
