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_vfRh):
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: "and"

Question 1 (Question id: q_6MIY):
Calculate -4 / 4 + 8.

Question 2 (Question id: q_ZDGzqD):
How many times does the letter "d" appear in the text: "law The invalidity"? Respond with an integer.

Question 3 (Question id: q_56ijUkZI):
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: "sports"



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'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.
• num_questions_answered: count of questions present in your JSON.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.
