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_4MEImv):
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: "patterns"

Question 1 (Question id: q_UBxG7ao):
Solve for r: 11*r + 187 = 319 Respond with an integer.

Question 2 (Question id: q_Sftn):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 beetle, 4 sea slugs, 3 insects?
 Respond with an integer.

Question 3 (Question id: q_WCOR):
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: "sold"

Question 4 (Question id: q_aMol):
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: "problems"

Question 5 (Question id: q_WwpE):
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: "on"



Produce a JSON object whose top-level keys are the question ids.

The value for each key should be an object that contains the answer in the field 'answer'.
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.
