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_R4lAeLRp):
Solve for r: 18*r + 3 = 57 Respond with an integer.

Question 1 (Question id: q_9idO5):
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: "study"

Question 2 (Question id: q_nggpE0M):
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 deers, 1 lion, 2 horses?
 Respond with an integer.

Question 3 (Question id: q_5qSZ):
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: "quickly"



Return a JSON with each question id (except for q_9idO5) as a key.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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.

{"ground_truth": {"q_nggpE0M": {"answer": 24, "additional_answer_info": {"half_answer": 12, "double_answer": 48}}, "q_R4lAeLRp": {"answer": 3}, "q_5qSZ": {"answer": "y", "first_char": "y"}}}
