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_eLRT):
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"

Question 1 (Question id: q_XRedDRJc):
How many times does the letter "a" appear in the text: "at no"? Respond with an integer.

Question 2 (Question id: q_7z8o58t):
Find the value of b in the equation: 256*b + 144 = 1680 Respond with an integer.

Question 3 (Question id: q_LLNZYc):
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 bird, 1 sea slug, 2 scorpions, 4 lions, 4 shrimps?
 Respond with an integer.



Create a JSON object keyed by every question id except q_LLNZYc.

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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.
'num_questions_answered' must hold the number of answered questions.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Also include 'combined_results' consisting of:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.
