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_Zvdqf):
Calculate 9 - 7.

Question 1 (Question id: q_AKFXvu):
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: "and"

Question 2 (Question id: q_0iFMo):
Determine the value of i that satisfies: i - 12 = 4 Respond with an integer.

Question 3 (Question id: q_dFnqoOeu):
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 starfishs, 2 jellyfishs, 4 ants, 2 snakes?
 Respond with an integer.

Question 4 (Question id: q_FqHyxiD5):
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 lobsters, 2 jellyfishs, 3 horses, 3 insects, 1 bird?
 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.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
