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_qOEF0R0):
How many times does the letter "t" appear in the text: "after the"? Respond with an integer.

Question 1 (Question id: q_FQv6RCm):
Find the value of l in the equation: 110*l - 7 = 1643 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'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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_qOEF0R0": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_FQv6RCm": {"answer": 15}}}
