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_PN1OPUl):
Calculate 0 - 2 - -5.

Question 1 (Question id: q_5AvlFD):
How many times does the letter "f" appear in the text: "Mars of any"? Respond with an integer.

Question 2 (Question id: q_Fftzn3f):
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 scorpions, 1 flatworm, 1 grasshopper?
 Respond with an integer.

Question 3 (Question id: q_1tMpZO):
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 elephant, 1 flatworm, 2 deers, 2 birds, 3 beetles?
 Respond with an integer.



Create a JSON object keyed by every question id except q_Fftzn3f.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to 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.

{"ground_truth": {"q_1tMpZO": {"answer": 34, "half_answer": 17}, "q_PN1OPUl": {"answer": 3}, "q_5AvlFD": {"answer": 1}}}
