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_Zg4tk):
How many times does the letter "e" appear in the text: "and lets"? Respond with an integer.

Question 1 (Question id: q_jaUQDhQ):
Find the value of d in the equation: -2*d - 16 = -34 Respond with an integer.

Question 2 (Question id: q_kvk5ybU):
How many times does the letter "i" appear in the text: "of obtaining"? Respond with an integer.

Question 3 (Question id: q_PeHf5):
Find the value of d in the equation: 12*d + 2 = 98 Respond with an integer.



Output JSON where all question ids are keys, omitting q_PeHf5.

The value for each key should be an object that contains the answer in the field 'answer'.
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.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
• num_questions_answered: count of questions present in your JSON.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.
