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_fWuao):
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: "and"

Question 1 (Question id: q_0wxej9yg):
Determine the value of k that satisfies: 2*k = 26 Respond with an integer.

Question 2 (Question id: q_tI8YfuT):
How many times does the letter "l" appear in the text: "all that we"? Respond with an integer.



Return a JSON with each question id as a key.

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'.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_fWuao": {"answer": "d", "first_char": "d"}, "q_0wxej9yg": {"answer": 13}, "q_tI8YfuT": {"answer": 2, "task_type": "letter_counting", "half_answer": 1}}}
