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_aWWd5):
Find the value of a in the equation: 19*a - 20 = 170 Respond with an integer.

Question 1 (Question id: q_WewXmT):
How many times does the letter "a" appear in the text: "of this agreement"? Respond with an integer.

Question 2 (Question id: q_XWkm):
How many times does the letter "l" appear in the text: "only three"? Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_WewXmT": {"answer": 1, "task_type": "letter_counting", "answer_type": "integer"}, "q_aWWd5": {"answer": 10, "answer_type": "integer", "half_answer": 5}}}
