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_CftC8):
How many times does the letter "d" appear in the text: "stupendous progress"? Respond with an integer.

Question 1 (Question id: q_buUSm5rt):
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 chicken, 2 scorpions, 4 insects, 4 elephants, 1 spider?
 Respond with an integer.

Question 2 (Question id: q_kPak9B):
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: "brains"

Question 3 (Question id: q_7Y7vy):
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: "know"



Produce a JSON object whose top-level keys are the question ids.

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.
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_CftC8": {"answer": 1}, "q_buUSm5rt": {"answer": 66, "half_answer": 33}, "q_kPak9B": {"answer": "s", "first_char": "s", "original_string": "brains"}, "q_7Y7vy": {"answer": "w", "first_char": "w", "original_string": "know"}}}
