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_H4AmKl9x):
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: "do"

Question 1 (Question id: q_FQEMUuRL):
How many times does the letter "h" appear in the text: "said he addressing"? Respond with an integer.

Question 2 (Question id: q_anoLeOK):
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: "not"

Question 3 (Question id: q_iG0nJoqI):
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: "happen"



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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).

Now provide the result JSON using the described format.

{"ground_truth": {"q_H4AmKl9x": {"answer": "o"}, "q_FQEMUuRL": {"answer": 1}, "q_anoLeOK": {"answer": "t"}, "q_iG0nJoqI": {"answer": "n"}}}
