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_IDBDTr2):
How many times does the letter "t" appear in the text: "the winds etc"? Respond with an integer.

Question 1 (Question id: q_sBZ8WAw):
Calculate ( ( -1 - -9 ) + -2 ).

Question 2 (Question id: q_TdxS1):
Determine the value of u that satisfies: -19*u - 2 = -59 Respond with an integer.

Question 3 (Question id: q_LyUImG):
Determine the value of d that satisfies: 33 - 15*d = -27 Respond with an integer.



Return a JSON with each question id 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.
