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_bXLvYoa):
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: "other"

Question 1 (Question id: q_wWnge2Pz):
Calculate -2 - -8.

Question 2 (Question id: q_3MT3s0jp):
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: "patience"

Question 3 (Question id: q_C9BPh):
Calculate ( 3 - -3 ).

Question 4 (Question id: q_R873Z):
Calculate -7 * -5 * 1.

Question 5 (Question id: q_ScUq):
Determine the value of j that satisfies: -20*j - 7 = -67 Respond with an integer.

Question 6 (Question id: q_3L2QaI):
Calculate 0 * 6.



Output JSON where all question ids are keys, omitting q_R873Z.

For every question id, supply an object whose 'answer' field stores the solution. 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 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.
