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_vm5Y):
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 sheep, 2 lions, 2 tigers, 4 cats, 1 scorpion?
 Respond with an integer.

Question 1 (Question id: q_rQlz):
How many times does the letter "u" appear in the text: "house You must"? Respond with an integer.

Question 2 (Question id: q_eoQqw):
Calculate ( -4 + -4 - -9 ).

Question 3 (Question id: q_YynBq):
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"



Output JSON where all question ids are keys, omitting q_rQlz.

Each key’s value must be an object holding an 'answer' field.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_vm5Y": {"answer": 44, "half_answer": 22}, "q_eoQqw": {"answer": 1}, "q_YynBq": {"answer": "d"}}}
