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_2tQ5m):
How many times does the letter "h" appear in the text: "not think of"? Respond with an integer.

Question 1 (Question id: q_GCbuc6Yu):
Determine the value of b that satisfies: 95*b + 1900 = 2090 Respond with an integer.

Question 2 (Question id: q_K88n):
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: "we"

Question 3 (Question id: q_7XKC8o):
Determine the value of d that satisfies: 11*d + 13 = 79 Respond with an integer.



Create a JSON object keyed by every question id except q_7XKC8o.

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.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.

{"ground_truth": {"q_K88n": {"answer": "e", "answer_type": "string", "first_char": "e", "original_string": "we"}, "q_2tQ5m": {"answer": 1, "answer_type": "integer"}, "q_GCbuc6Yu": {"answer": 2, "answer_type": "integer", "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "global_metadata": {"num_questions_asked": 4}}}
