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_bsfM):
Solve for d: 378*d = 7560 Respond with an integer.

Question 1 (Question id: q_YQ18kwt):
How many times does the letter "b" appear in the text: "2889 This ebook"? Respond with an integer.

Question 2 (Question id: q_A10s3):
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: "cycle"

Question 3 (Question id: q_mVfmjX):
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 praying mantis, 3 elephants, 1 crab, 4 horses, 4 bees?
 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_bsfM": {"answer": 20, "half_answer": 10}, "q_YQ18kwt": {"answer": 1}, "q_A10s3": {"answer": "e", "original_string": "cycle"}, "q_mVfmjX": {"answer": 68, "half_answer": 34}}}
