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_f7BcAhbK):
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: "rules"

Question 1 (Question id: q_WCUUKHn):
How many times does the letter "e" appear in the text: "not met"? Respond with an integer.

Question 2 (Question id: q_SqRX2w):
How many times does the letter "b" appear in the text: "being here I"? Respond with an integer.

Question 3 (Question id: q_bGfq8loV):
How many times does the letter "h" appear in the text: "turn the"? Respond with an integer.

Question 4 (Question id: q_g9Eff):
Solve for g: 11*g - 18 = 26 Respond with an integer.

Question 5 (Question id: q_tExMPC9):
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: "services"



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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
