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_Ekq3Fc):
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: "membrane"

Question 1 (Question id: q_8eFO):
How many times does the letter "m" appear in the text: "and Madrid but"? Respond with an integer.

Question 2 (Question id: q_ojrMDl):
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 giraffes, 1 sheep, 2 elephants, 4 tigers?
 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
