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_DYBw):
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: "be"

Question 1 (Question id: q_zivoRr):
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: "those"

Question 2 (Question id: q_RJUI0):
How many times does the letter "o" appear in the text: "Sir John"? Respond with an integer.

Question 3 (Question id: q_npLemO):
Calculate ( ( -3 * -3 ) ) / 1.

Question 4 (Question id: q_g1UgTi4):
Solve for c: 13 - 19*c = -196 Respond with an integer.



Return a JSON with each question id (except for q_RJUI0) as a key.

Each key’s value must be an object holding an 'answer' field. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
