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_3iXI):
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: "the"

Question 1 (Question id: q_SPCa2U):
Solve for d: 1170*d = 12870 Respond with an integer.

Question 2 (Question id: q_y9Prz):
How many times does the letter "h" appear in the text: "To this"? Respond with an integer.

Question 3 (Question id: q_rN580):
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: "push"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
