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_EpejwTi2):
How many times does the letter "b" appear in the text: "must be mended"? Respond with an integer.

Question 1 (Question id: q_FYrybYq):
Calculate 7 * 4 - -7.

Question 2 (Question id: q_VJyZQi7):
How many times does the letter "e" appear in the text: "remained silent A"? Respond with an integer.

Question 3 (Question id: q_FP5bepH):
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: "makes"

Question 4 (Question id: q_PNDcPX):
Calculate 1 * 1.



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.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
