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_rak7bAy):
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: "food"

Question 1 (Question id: q_6JJHIz):
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: "like"

Question 2 (Question id: q_tKEA):
Solve for z: -14*z - 3 = -213 Respond with an integer.

Question 3 (Question id: q_qHf1Dfn):
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: "talent"

Question 4 (Question id: q_3BCxshoc):

Find the value of o in the equation: 31 - o = 22 Respond with an integer.

Question 6 (Question id: q_8AeMCPb):
Calculate 0 * -5.



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.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
