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_INaSG):
Solve for r: 18*r + 3 = 57 Respond with an integer.

Question 1 (Question id: q_VkAqiuX):
How many times does the letter "d" appear in the text: "building a vast"? Respond with an integer.

Question 2 (Question id: q_xsOQgm):
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 3 starfishs, 4 cows, 1 cat?
 Respond with an integer.



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

The value for each key should be an object that contains the answer in the field 'answer'. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_INaSG": {"answer": 3}, "q_VkAqiuX": {"answer": 1, "task_type": "letter_counting"}, "q_xsOQgm": {"answer": 35, "task_type": "leg_counting"}}}
