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_9hC1):
How many times does the letter "b" appear in the text: "believed to"? Respond with an integer.

Question 1 (Question id: q_aHbw7):
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 2 (Question id: q_tRqR):
Determine the value of q that satisfies: 2*q + 8 = 22 Respond with an integer.

Question 3 (Question id: q_6C7T5r):
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 4 (Question id: q_WXFJm):
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: "compete"



Return a JSON with each question id (except for q_WXFJm, q_6C7T5r) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_tRqR": {"answer": 7, "answer_type": "integer"}, "q_aHbw7": {"answer": "o", "answer_type": "string", "first_char": "o"}, "q_9hC1": {"answer": 1, "answer_type": "integer"}}}
