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_C1VH5):
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: "the"

Question 1 (Question id: q_fR8z8Qs):
How many times does the letter "e" appear in the text: "located before"? Respond with an integer.

Question 2 (Question id: q_C9G0Bji):
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: "move"



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

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

{"ground_truth": {"q_C1VH5": {"answer": "e", "first_char": "e"}, "q_fR8z8Qs": {"answer": 3}, "q_C9G0Bji": {"answer": "e", "first_char": "e"}}}
