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_yfJ1am):
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: "cells"

Question 1 (Question id: q_k8oK):
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 2 humans, 4 woodlouses, 2 chickens?
 Respond with an integer.

Question 2 (Question id: q_IoGCJE):
How many times does the letter "r" appear in the text: "or using"? Respond with an integer.

Question 3 (Question id: q_Nc6taeKD):
Calculate ( 2 - -6 ).



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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).
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
Record the answered-question count in the field 'num_questions_answered'.

Attach a 'combined_results' object that contains:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.
