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_5fIlP):
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 cats, 3 giraffes, 1 crab, 1 cow?
 Respond with an integer.

Question 1 (Question id: q_GOURZ3Lx):
Calculate ( 3 * 7 ).

Question 2 (Question id: q_1JQdlLz):
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 flatworms, 3 elephants, 1 snake, 3 woodlouses?
 Respond with an integer.

Question 3 (Question id: q_tbtlpHb):
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: "a"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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 question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.
