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_Ud3n7gw):
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: "and"

Question 1 (Question id: q_xfume):
Find the value of z in the equation: 20 - 4*z = -36 Respond with an integer.

Question 2 (Question id: q_pGoq):
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: "environment"

Question 3 (Question id: q_B8Aij):
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 1 cricket, 2 flatworms, 1 cat, 3 snakes, 4 lobsters?
 Respond with an integer.

Question 4 (Question id: q_bXJq):
Find the value of x in the equation: 6*x + 208 = 274 Respond with an integer.

Question 5 (Question id: q_XpTa):
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 lion, 3 fireflys, 4 crabs, 2 bees?
 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).
For last-character tasks, provide 'original_string' alongside the answer.
For animal-leg questions, add 'animal_types': an alphabetically-sorted list of unique animal names in singular form.

Now provide the result JSON using the described format.
