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_8oDbOfW):
How many times does the letter "d" appear in the text: "a day"? Respond with an integer.

Question 1 (Question id: q_Mq71Sn):
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: "opponents"

Question 2 (Question id: q_4bVVi9Z):
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: "their"

Question 3 (Question id: q_WHSwc3):
Calculate ( 5 + 2 ).

Question 4 (Question id: q_6IfyTMpy):
Calculate ( ( 2 + 3 ) ).

Question 5 (Question id: q_8bjDMjV):
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: "getting"

Question 6 (Question id: q_kK4cOXTh):
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: "machines"



Create a JSON object keyed by every question id except q_8bjDMjV, q_kK4cOXTh.

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
