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_EeW9w7te):
How many times does the letter "o" appear in the text: "donations to the"? Respond with an integer.

Question 1 (Question id: q_LDUz):
Determine the value of x that satisfies: 20 - 6*x = 2 Respond with an integer.

Question 2 (Question id: q_WosJotva):
Solve for f: 13 - 5*f = -22 Respond with an integer.

Question 3 (Question id: q_7xdtj3):
How many times does the letter "r" appear in the text: "the morning"? Respond with an integer.

Question 4 (Question id: q_2JnIEKKL):
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: "with"

Question 5 (Question id: q_PEyObs5):
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: "what"



Output JSON where all question ids are keys, omitting q_WosJotva.

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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
