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_PLOE5):
Calculate ( 6 - 4 ).

Question 1 (Question id: q_sng5gxs):
Solve for o: -20*o - 23 = -83 Respond with an integer.

Question 2 (Question id: q_qGOW4V):
How many times does the letter "e" appear in the text: "people who"? Respond with an integer.

Question 3 (Question id: q_eBMBQq):

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: "and"



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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.

Now provide the result JSON using the described format.
