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_shPN7):
Find the value of d in the equation: -2*d - 16 = -34 Respond with an integer.

Question 1 (Question id: q_lkP0fUm0):
How many times does the letter "t" appear in the text: "of State"? Respond with an integer.



Return a JSON with each question id (except for q_lkP0fUm0) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.
