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_FB8VoW):
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: "or"

Question 1 (Question id: q_pWg89j):
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, 3 woodlouses?
 Respond with an integer.

Question 2 (Question id: q_17h7Cl):
Calculate ( -3 + 5 ).



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

For every question id, supply an object whose 'answer' field stores the solution.
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 last-character tasks, provide 'original_string' alongside the answer.
When counting animal legs, include an 'animal_types' list of the distinct animal names (singular, sorted).

Now provide the result JSON using the described format.

{"ground_truth": {"q_FB8VoW": {"answer": "r", "original_string": "or"}, "q_pWg89j": {"answer": 70, "half_answer": 35, "animal_types": ["cat", "giraffe", "woodlouse"]}, "q_17h7Cl": {"answer": 2, "half_answer": 1}}}
