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_CEK8Lz):
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: "of"

Question 1 (Question id: q_SuDF):
Calculate ( 0 + 9 ).

Question 2 (Question id: q_2qlIk):
Calculate ( 9 + 4 ) - -1.

Question 3 (Question id: q_rXguewgV):
How many times does the letter "i" appear in the text: "binary compressed marked"? Respond with an integer.

Question 4 (Question id: q_V833cwCH):
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 scorpions, 4 elephants, 1 cricket, 1 chicken, 1 shrimp?
 Respond with an integer.



Return a JSON with each question id (except for q_V833cwCH, q_2qlIk) as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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 string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_SuDF": {"answer": 9, "answer_type": "integer"}, "q_rXguewgV": {"answer": 1, "answer_type": "integer"}, "q_CEK8Lz": {"answer": "f", "answer_type": "string", "first_char": "f"}}}
