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_y8EnvI):
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: "explain"

Question 1 (Question id: q_vFX0):
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: "cup"

Question 2 (Question id: q_vp5KpB):
Calculate -9 * -9 + 3.

Question 3 (Question id: q_Sdv8iT):
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: "time"

Question 4 (Question id: q_R8IgrD):
Determine the value of u that satisfies: -19*u - 2 = -59 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'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered – number you actually answered.

Now provide the result JSON using the described format.
