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_YaVJQnq):
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: "give"

Question 1 (Question id: q_B7fc):
How many times does the letter "e" appear in the text: "whether as heat"? Respond with an integer.

Question 2 (Question id: q_o8m0v61x):
How many times does the letter "f" appear in the text: "about face"? Respond with an integer.

Question 3 (Question id: q_fH5FtcGV):
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: "is"

Question 4 (Question id: q_nSVQP5A):
How many times does the letter "u" appear in the text: "37 up"? 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'.
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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.
