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_f9Bp9):
Calculate 1 + 3.

Question 1 (Question id: q_h5Hic7i):
How many times does the letter "l" appear in the text: "death he unhesitatingly"? Respond with an integer.

Question 2 (Question id: q_Tto8v):
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 3 (Question id: q_aW30bS):
Calculate 8 - -1.

Question 4 (Question id: q_XUM5K7):
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: "to"

Question 5 (Question id: q_BKsmeRlF):
How many times does the letter "t" appear in the text: "a half interest"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_h5Hic7i, q_aW30bS.

The value for each key should be an object that contains the answer in the field 'answer'. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
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).
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.
